CaC2 + 2 H2O -> CA(OH)2 + C2H2

Chlorine is more electro-negative than SULPHUR because chlorine has only ONE valency. It can easily donate the electron or GAIN only one electron from any other element. But sulphur has 2 valency. It has to gain 2 electrons from any other element.

Because it is HARD and SHINY

Hello –--------–>>☺️ ☺️ ☺️☺️

➡️ The decaying animals are CALLED saprophytes....

➡️ DECOMPOSERS such as BACTERIA and fungi cause decay at a microscopic level.

➡️Other larger ORGANISMS called detritivores


➡️ help speed up decay by FEEDING on detritus.

➡️This is dead and decaying material.

When excess of co2 is passed through LIMEWATER caco3 ( calcium CARBONATE ) is formed which is WHITE in colour

Number of MOLES= given MASS /TOTAL mass
N= w/m
mass of HCl= 1+35.5=36.5

n= 109.5/36.5 = 3
There are three moles of HCL are PRESENT in 10 9.5 gram of HCL.

Large animals cannot maintain gas exchange by DIFFUSION across their outer surface dost gases can only cross cell MEMBRANE when they are dissolved in WATER or an aqueous solution , THUS respiratory ORGANS must be moist.

animal:

silk,wool..

mineral:

GOLD,silver..

2. Man made fiber(ARTIFICIAL fiber)

synthetic:

nylon, polyster..

regenerative:

Rayon

Answer:

Following are the characteristic features of PHANEROGAMS:

They have well-differentiated plants i.e. the plant body is divided into distinct ROOT, SHOOT, and leaves.

These are multicellular, eukaryotic and chlorophyll containing plants.

These are photoautotrophic and produce own food by photosynthesis.

These are flowering plants.

These have vascular system i.e. xylem and phloem tissues.

These are higher terrestrial plants and can be found in deserts, on mountains, and in rainforests.

Here the reproductive organs are found in the flowers and are visible.

The life cycle of phanerogams is completed in two generations sporophytic generation and gametophytic generation. This is ALSO known as alternation of generation.

The plant body is a sporophyte and diploid.

The gametophytic phase is much REDUCED in phanerogams.

Infectious diseases are illnesses that are CONTAGIOUS, meaning they can be spread from one person to ANOTHER. Infectious diseases are caused by microorganisms, CALLED pathogens, or what we commonly refer to as germs. Viral and bacterial infections are the most COMMON causes of infectious DISEASE.

Fern is a plant that GROWS WELL in RAINFOREST .they are an ornamental plant that can be grown in our homes also. Buds OPEN and Fern spread out to soak up the LIGHT.

Transmittance. When light MOVES through a transparent (or semi-transparent) MATERIAL, it can betransmitted, ABSORBED, or reflected. The transmittance of a material is the proportion of the incident (approaching) light that moves all the way through to the other side.

absorption - light absorption is the process by which light is absorbed and converted into energy.
reflection of light- when a light falls on a smooth surface it REFLECTS back making an 90° angle with incident light is called reflection of light

Diesel can obtain from petrol. The Diesel is one of the products that is CREATED from the crude oil.

REFINING PROCESS has viscous dark thick crude oil is turned into MUCH lighter diesel fuel.

Crude oil is produced by different METHOD and it is highly suitable for many number of process.

Pollination is the transfer of pollen from a male part of a plant to a female part of a plant.

Honeybees, The most well-known pollinator, honey BEES are credited with pollinating much of the FOOD we eat. They are considered the most important insect known to humans.

WILD bees: Wild bees in North America are responsible for pollinating both wild and AGRICULTURAL plants.

Birds

Some birds, especially hummingbirds, pollinate plants. The plants that attract birds are generally brightly coloured, with red, orange or yellow FLOWERS, but are often odourless, since birds have a poor sense of smell.

hope this helped :)

Answer:

characteristics of coal-

#Anthracite coal is a DENSE, hard rock with a jet-

#86% and 98% carbon by weight, & it burns.

#Bituminous coal (in Indiana), contains between.

#69% & 86% carbon by weight.

#Sub-bituminous coal contains less carbon, more.

#Lignite coal, or brown coal, is a very soft coal that.

contains up to 70% water by weight. Emits more.

uses of coal-

The most significant uses of coal are in electricity generation, steel production, cement MANUFACTURING and as a LIQUID FUEL. Steam coal - also known as thermal coal - is mainly used in power generation.

Because PRESENCE of MOISTURE

Let the DISTANCE from o to pay =x
Time TAKEN to cover x =18sec
We know, Average Speed = total distance /total time
i) distance =x, time =18
HENCE, speed =x/18 - - - - - (1)
Also, average velocity = total displacement /total time
Hence, displacement =x and time =18
Velocity =x/18

ii) distance =2X

Because to ATTRACT INSECTS for POLLINATION.

1.a) blue green algae and nostoc
b) 30° to 50°

2.a) penicillin

3.The percentage of nitrogen in atmosphere is kept constant through nitrogen cycle.The sequence in which nitrogen in the atmosphere is passed into the soil and lifeforms, and then released back into the atmosphere, is called the nitrogen cycle.

a) Nitrogen fixation: The process of conversion of atmospheric nitrogen into nitrogenous compounds and making it available for plants is called as nitrogen fixation. Nitrogen fixation can happen by biological processes or physical processes. Nitrogen is introduced to the soil by fertilisers or animal and plant residues.

b) AMMONIFICATION: The process of production of ammonia from organic compounds is called ammonification. Ammonification is the process CARRIED out by a variety of microorganisms that breakdown protein, amino acids, and othernitrogen-containing compounds of dead and waste organic matter to form ammonia.

c) Nitrification: It is the process by which ammonia is converted to nitrites (NO2-) and then to nitrates (NO3-). This process naturally occurs in the environment, whereit is carried out by SPECIALISED bacteria. Nitrosomonas and nitrobacter are the bacteria which bring about nitrification.


d) Denitrification: It is the biological conversion of nitrate to nitrogen gas, nitricoxide or nitrous oxide. These compounds are gaseous compounds and are not readily available for microbial growth. THEREFORE, they are typically released into atmosphere. This process is BROUGHT about by denitrifying bacteria.

The IUPAC NOMENCLATURE for N-heptyl-N-octylamine is
N-Heptyloctanamine.

Bhai baat BATAUNGA to aasaan shabdo mei........mere khayal SE na is ka answer kuch aisa hoga....

growth movement is a special type of movement in which cells in the organism body are subdivided due to which more number of cells are accumulated in body due to which growth I.e. enlargement of the body structures takes place.......

TURGOR movement is a movement in which large number of extracellular and intracellular material is accumulated inside the body causing the application of pressure on body wall due to which body gets stretched............it can be seen in the case of stomata of leaves.......

bhai pasand aaya ho toh mere wale brainliest option PE hit mar ke dekhna.....MATA Rani ashirvad degi.....

It can be SAID as a FLOW CHART .

It is a WHOLE PROCESS if U want you can TEXT me in COMMENTS section I'll send it a picture of it

Hey Guys,

NON METALS :- 1) Oxygen, 2) Iodine, 3) Chlorine.


Non metallic minerals are those which FOUND in liquid or GASEOUS states.

Thanks.

False
instead of DECANTATION it can be filtration
☺☺

The ANSWER is SIEVE as the METHOD of sieving TAKES place

1.Cell Type => Eukaryotic
2.Cell wall=> cell wall is present but without cellulose.
3. Nuclear membrane=> present
4. Body ORGANISATION=> multicellular/ LOOSE tissue
5.Mode of Nutrition=> HETEROTROPHIC (SAPROPHYTIC/ parasitic)

Methods to remove PESTS from field
1. crop rotation..
2. NON chemical.
3. mechanical..

D) IRON is the ANSWER.

no, we cannot. Different PEOPLE need different amounts of minerals and protein,

ex. 1 PERSON MAY lack protein and ANOTHER person may not. If we give them both the same diet. The first person will STILL have less protein then the second.

Hey mate
The mean difference (more correctly, 'difference in MEANS') is a STANDARD statistic that measures the absolutedifference between the mean VALUE in two groups in a clinical trial. It estimates the AMOUNT by which the experimental intervention changes the outcome on average compared with the control.

Pitcher plant has dual mode of nutrition. It has chlorophyll so it performs photosynthesis using CARBON dioxide, water, and SUNLIGHT and prepare carbohydrates.
But pitcher plant grows in swampy area in bogs where there is a deficiency of NITROGEN. In a pitcher plant, the leaf is modified into a pitcher like structure. The TIP of leaf forms a lid that can open and close the mouth of the pitcher. When an insect gets attracted towards the pitcher and lands on it, the lid close. The pitcher secretes digestive juices which digest the TRAPPED insect.
