During neutralization reavtion does the temperature of contains increase and why

Answer»

In chemistry, neutralization or NEUTRALISATION(see spelling differences), is a chemical reaction in which an ACID and a base react quantitatively with each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions PRESENT in the solution. The pH of the neutralized solution depends on the acid strength of the reactants. Neutralization is USED in MANY applications.

Name the various type of silk with example

Answer»

There are four types of natural silk which are COMMERCIALLY known and produced in the world.  Among them MULBERRY silk is the most important and contributes as much as 90 per cent of world production, therefore, the term "silk" in general refers to the silk of the mulberry silkworm. Three other commercially important types fall into the CATEGORY of non mulberry silks namely: Erie silk; Tsar silk; and mulga silk.  There are also other types of non mulberry silk, which are mostly wild and EXPLOITED in AFRICA and Asia, are ayaphe silk, cane silk, Mussel silk and Spider silk.

In  a  bar  magnet  is  suspended  vertically  it  does  not  hangin  the  north-south  direction.MSCERT Class 8th General Science Ch4 Magnetism

Answer»

A freely suspended Bar magnet comes to  rest in the N_S direction because

--->The alignment of a freely suspended particles in magnet are influenced by EARTH's magnetic field.

---> Earth is ASSUMED to be a huge strong magnet with its SOUTH pole near its Geographical North pole and North pole at its Geographical south pole.

--> HENCE when suspended freely  the North pole of magnet points TOWARDS geographic north and south pole of bar magnet points Geographic south pole. 

If bar magnet is suspended vertically , then it remains at rest ... Because magnetic particles alignment will not come in effect of earth's magnetic field.

Two resistance when connected in parllel give resultant value of 2 ohm when connected in series the value become 9 ohms. Calculate the value of each resistane

Answer» LET R1 and R2 be the two resistances. When they are in parallel, resultant resistance Rp is given by

1/Rp = 1/R1 + 1/R2
Rp = R1R2/(R1 + R2)
2 = R1R2/(R1 + R2)
2(R1 + R2) = R1R2

When they are in series effective resistance 

Rs = R1 + R2
9 = R1 + R2 ⇒ R2 = 9 - R1

2 x 9 = R1 R2
          = R1 (9 - R1)
          = 9R1 - R12.
18 = 9R1 - R12.
R12 - 9R1 + 18 = 0

Solve this quadratic equation. You will get 

R1 = (9 ± √(81 - 4 x 1 x 18))/2
      = (9 ± √9)/2
      =  (9 ± 3)/2
R1 = 3 ohm or 6 ohm

If R1 = 3 ohm, R2 = 6 ohm and vice versa.

50 pointsBriefly explain phylum Annelida?

Answer»

✨Heya!!!!✌

✍Your answer⬇⬇⬇⬇

⭐Phylum Annelida⤵

⏩The phylum Annelida includes metametrically segmented animals with a true coelom

⏩Annelids are TRIPLOBLASTIC and bilaterally symmetrical animals with organ-system grade of organization. Annelids show true body segmentation: their bodies are divided into definite sections or segments. Annelids can control each SEGMENT separately and continue to add segments THROUGHOUT life

⏩The body is covered by definite cuticle secreted from the ectoderm. Body wall has both longitudinal and circular muscles. These contracts alternately against the fluid-filled septate coelom during locomotion. Bristles of chaetae(or setae) present on the lower side of the body help grip the ground during locomotion

⏩Annelids have a true coelom(a fluid-filled body CAVITY) and a gut. The coelom is important for the transport of body fluids and discharge of gametes, and it also acts as a hydrostatic skelton

Collect the information about importance of PH value in daily life to human being as well as plants

Answer»

Most life processes can occur within a narrow range of PH. For example, the PH of blood is tightly regulated in the range of 7.2 to 7.4. Similarly, the PH value of the soil is of great importance in agriculture. Most food crops grow BEST at a PH of 7-7.8. The growth of plants suffers when the PH value is outside this range. The PH of soil is usually tightly regulated by the microflora present in the GROUND. However, excessive use of ammonia-based fertilisers can make the soil acidic.

Have you heard of acid rain? The atmosphere contains gasses like nitrous oxide and sulphur oxide. When these dissolve in rain, they produce NITRIC and sulphuric acid. If the concentration of these acids in high in rainwater, it can lower the PH value. Acid rain has a value of less than 5.6 on the PH scale. ?Acid rain is another cause of the increase in soil acidity.

The PH scale plays a critical role in the human body. Different parts of the human body have different PH. The mouth has a SLIGHTLY alkaline PH while the stomach has a very acidic PH. The skin has a slightly acidic PH, and the PH in the Vagina is again very acidic. Why is this so?

The saliva in the oral cavity makes the PH of the mouth alkaline. The alkaline PH facilitates the action of salivary enzymes. It also prevents tooth decay. Why do we wash our mouth after eating anything? The sugars present in the food can ferment to produce acid. This acid can damage the enamel of the teeth, thus causing tooth decay.

The PH of the stomach is between 1.3 -2. The glands in the stomach secrete a hydrochloric acid that makes the PH of the stomach acidic. The acidic PH SERVES two functions- it kills any microorganisms, and it facilitates the action of enzymes like trypsin.

Similarly, the acidic PH of the skin and vagina prevent colonisation by bacteria, thus serving as a natural defence against infection.

How is water wasted in your surroundings everyday

Answer»

(1) Dishwasher- Dishwashers can waste so much water if you run it when it is not full. A way to prevent this is to wash your dishes without use of the dishwasher. If you do need to use a dishwasher, make sure it is completely full before you turn it on. If you can buy a new dishwasher, invest in an Energy Star or other energy efficient dishwashers.

(2) BRUSHING Teeth / Washing Dishes WITH the Water Running- DO NOT keep water running while brushing your teeth/ doing the dishes. When you brush your teeth, wet the toothbrush FIRST and turn the water off immediately. And use a natural toothpaste, like Tom’s of Maine.Only use the water to rinse. Same for dish washing. Scrub the dishes without the water on, and then turn the water on to rinse off the soap. I hope you are using a BIODEGRADABLE Soap, like Seventh Generation. These soaps are made %100 naturally, and help the petrolium levels in the air. This is what is used in my house, and it makes me feel good about doing the dishes.

(3) Shaving (Men)- Men, you do not need the water running when you shave. Fill the sink up a little less than halfway, and use that water to rinse your blade.

(4) Shaving (Women)- When you shave in the shower, do you really need the water running? Turn off the water while you shave your legs. I put conditioner in my hair, fill cup with water, sit in the bathtub and shave, with the water off, while my hair is being conditioned!

(5) If Its Yellow, Let it Mellow. If Its Brown, Flush it Down- Some people are bothered by this, but it is essential. Every time you flush the toilet, you waste 10 gallons of water. So why not just flush when necessary?

(6) Car Wash-This may be hard for us city folks, but if you have a lawn, Wash your car on it! Use Biodegradable soap, like Simple Green’s Car Wash , and a bucket of water. Only turn on the HOSE for the final rinse. Your car will be clean, your lawn will be fed, and by doing this you know you did a lot to help the environment.

(7) Leaky Toilets / Leaky Faucets-If you notice a leaky pipe, faucet, or toilet, get it fixed immediately. A leaky toilet, for example, can waste up to 200 gallons of water a DAY. So please, fix your water problems.

(8) Bathtime! Bathtime is no longer Funtime. It wastes an unnecessary amount of water. an average shower uses 1/5 the amount of water that is needed for a bath! Teach kids to take showers early on. It all really adds up. So please, take a shower not a bath.

(9) Using the Toilet as a Garbage Can-Do Not Do This! Throw out everything in a garbage can, even if it is tempting to just throw it in the toilet. Tissues, Hair, and Bugs are things that people generally throw away in the toilet, but they will be disposed if thrown away in the garbage can as well.

(10) Hot Water-Only use hot water when absolutely necessary. Hot water uses a lot more energy, and it isn’t always necessary. So think about what is needed before turning that hot water knob!

To know about the different method of prevention

Answer»

To prevent pregnancy naturally using Cycle Beads, a woman should avoid having unprotected intercourse on days 8-19 of her cycle, where the start of her cycle, Day 1, is the FIRST day of her period. This means that during the days when she is potentially fertile, she should EITHER abstain from intercourse or USE a back up family planning method such as a condom. She should also track that her cycles are between 26 and 32 days long.

Some Birth Control Method -

Birth control pills - Birth control pills, often referred to in shorthand as "the Pill," consist of synthetic estrogen and progestin hormones that keep a woman's eggs from leaving her ovaries, so that pregnancy can't happen. When taken properly, they are extremely effective.

The Pill must be taken every day, at the same time each day, to WORK properly. Skipping a few days could decrease its efficacy.he Pill causes some women to experience side effects. Different brands of pills have different levels of estrogen and progestin.

2. Other hormonal devices - The same hormones that make birth control pills effective can be DISTRIBUTED to the body by other means.

Depo-Provera, or the birth control shot. This shot is administered in the arm once every three months.The birth control patch. The patch is usually placed on the arm, back or thigh. It distributes hormones through the skin and has to be replaced every few weeks.The birth control ring. The ring is inserted into the vagina once a month. It releases hormones to prevent pregnancy from occurring.

3. Intrauterine Devices (IUD) -he IUD is a small metal device inserted in the uterus by a health care provider.
