procedure:1. ALWAYS add ACID to the water, not the other way around. ...2. When mixing two acids, always add the stronger acid to the weaker.3. It is possible to add half the required amount of water, diluting it FULLY, then slowly mixing in the REMAINING water.

Gases, liquids and solids are all made up of atoms, MOLECULES, and/or ions, but the BEHAVIORS of these particles differ in the three phases. ... GAS are well SEPARATED with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, USUALLY in a regular pattern

Explanation:FARMERS store food grains in JUTE or gunny bags after harvesting. Gunny bags are easy to transport collective of grains from ONE place to ANOTHER. The primary reason is that gunny bags prevents grains from exposure to moisture and protects it from insects and BACTERIA's.

1) the smell of food being CLOCKED in the kitchen reaches us even from a considerable distance2) the smell of perfume SPREADS DUE to the diffusion of perfume vapour into the air

move our hand FREELY through AIR but not through WOOD because air has atoms far AWAY and they have huge SPACES between them Hope this helps.

We can easily move our HANDS in air because the particles of air have LARGE SPACES between them and less force of attraction.Whether, in a plank of wood, the particles are CLOSELY packed and the force of attraction is also high.Due to this reason we can easily move our HAND in air but not in a plank of wood.

The particles of matter are very small.To PROVE this TAKE a BEAKER with water inside it and mark the water level.Now add a spoon of SUGAR or salt and then mix it well.Can you see any rise in the water level in the beaker?The answer is no.This is because all the sugar or salt molecules gets inside the small intermolecular spaces present between the water molecules.HOPE IT HELPSMARK AS BRAINLIEST

Polymer is a SUBSTANCE made up of a large number of smaller MOLECULES that link together to form larger molecules. An EXAMPLE of a synthetic polymer is plastic. An example of a NATURAL polymer is rubber.

Malleability is a substance's ability to deform under PRESSURE (compressive stress). If malleable, a material may be flattened into THIN SHEETS by hammering or rolling. ... Examples of malleable metals are gold, iron, aluminum, copper, SILVER, and lead.HOPE THIS HELPS YOU ✌️

Most of the materials are there in our surrounding which are the mixtures of two or more components. For example, when we need to OBTAIN PURE water from dirty water then, we have to purify the substances i.e. dirty water or we might filter it or distil it.heterogeneous mixture are mixtures of two or more substance with non uniform compositioneg SAND and saltis solution is a heterogeneous mixture of two or more non reacting substances whose composition can be varied within certain limits iron fillings , ammonium chloride, sandkerosene oil, water , sandthe reason is that the process of seperating these substances in above mentioned ORDER is much easier than TAKING each one of them

Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they UNDERGO during a reaction with other substances.[1][2]In the scope of its subject, chemistry occupies an intermediate position between physics and biology.[3] It is sometimes called the central science because it provides a foundation for understanding both basic and applied scientific disciplines at a fundamental level.[4] For example, chemistry explains aspects of plant chemistry (BOTANY), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology), the properties of the soil on the moon (astrophysics), how medications work (PHARMACOLOGY), and how to collect DNA evidence at a crime scene (forensics).Chemistry addresses topics such as how atoms and molecules interact via chemical bonds to form new chemical compounds. There are four types of chemical bonds: covalent bonds, in which compounds share one or more electron(s); ionic bonds, in which a compound donates one or more electrons to another compound to produce ions (cations and anions); hydrogen bonds; and Van DER Waals force bonds.Explanation:I hope this helps you

Humidity is the amount of moisture or water vapour PRESENT in air at any moment in TIME. On a rainy day, the air is full of water vapour. As the air gets warmer, its CAPACITY to hold the water vapour increases. ... Hence, WET clothes take LONGER time to dry on a rainy day

E!!❤Spontaneous combustion or spontaneous ignition is a type of combustion which occurs by self-heating (INCREASE in temperature DUE to exothermic internal REACTIONS), FOLLOWED by thermal runaway (self heating which rapidly accelerates to HIGH temperatures) and finally, autoignition.[1]HOPE IT HELPS!!❤☺@BRAINLY.IN♡♡SRITI♡♡

Chemical Change: ... BOILING of EGG a chemical change.In CASE of boiling egg the composition of egg is IRREVERSIBLE. New substance is formed so it irreversible. Boiling of water is a PHYSICAL change.

SWER IS pottasium and sodium are stored in KEROSENE oil because if we STORE them in WATER then they will react with water and therefore we KEEP them in kerosene0il.Hope it helps YOUMARK my answer as brasinliest

as a responsible CITIZEN what measures do you suggest to keep public PLACES clean and FREE from PLASTIC. Plastic material such as polythene bags, plastic discard should not be THROWN in open places. Also, we should keep two dustbins in our house, one for organic garbage and other for plastic waste

re !! here is your answer!! Hope it helped !please mark it as the brainliest answer! Answer:Hey there!! Chemistry is very fun and interesting !!I have learnt this last year, so let me help you!! Please mark as the brainliest answer!! Explanation:c. Litmus, since it is  a natural indicator obtained from the plant lichen. d. FORMIC Acid, Since that is the acid that is injected into the skin when an ant bites, which is why it swells. So, we need to add a base( baking soda) to neutralize the acid , and give relief. e. Pink, as different indicators have different colours in order to differentiate between an acid and a base. Phenolphtalein is colourless in acids and pink in bases. 2. Match the following: 1. Acere- Sour( as it is the LATIN WORD for acid which means sour)2. Lime water- calcium hydroxide( as it is the dilute (which means it is dissolved in water) version of calcium hydroxide. )3. Anthocyanin- china rose, ( as the petals of china rose are red due to the presence of Anthocyanin in it. )4.Caustic soda- Sodium hydroxide,( as it is the liquid version of Sodium hydroxide, and it is used for cleaning. )5.Acetic acid-Vinegar, (as vinegar contains acetic acid. )6.Methyl Orange - synthetic indicator, as it is an indicator that is madd by humans and is not obtained naturally, thus it is a synthetic indicator. )3. State WHETHER true or false: a. True, as acids turn blue litmus paper red, and bases turn blue litmus paper blue. b. False. They only detect wheter a GIVEN substance is acidic or basic. c. True, a strong acids can burn hands and corrode paper and metal easily, so they should be handled with care. d. False, this is because phenolphthalein is a synthetic indicator and not a natural one. 4. Find the odd one out. a. Vinegar, as it is the only acid, rest all are bases. b. Methyl Orange, as it is the only synthetic indicator, rest all Are organic indicators. c. Citric acid, as it is the only origanic acid found in citrus fruits like oranges, whereas all others are mineral acids. 5. What do you understand by the term organic acids? name the origanic acids present in curd and vinegar. ANS. Origanic acids are acids that are obtained naturally from the earth or from a food product. They are very weak acids and dont corrode the skin, and are not corrosive. These are usually weak acids. origanic acids present in curd and vinegar: Curd- Lactic acidVinegar- Acetic acid. 6. what are mineral acids? give few examples of mineral acids. Ans. Mineral acids are those that are not obtained naturally from nature. these acids can corrode skin easily, and are usually corrosive , and are strong acids. For eg: sulfuric acid, hydrochloric acid.
