Ground sources such as groundwater, springs, hyporheic zones and AQUIFERS. Precipitation which includes rain, hail, snow, FOG, etc. SURFACE water such as rivers, streams, glaciers. BIOLOGICAL sources such as plants.these are all sources of consumable water.

When the system moves from 2E level to E level, aphoton of WAVELENGTH 2 is EMITTED. The wavelength of4Ephoton PRODUCED during the transition from to Elevel isExplanation:I will give you the answer of this question LETTER

The oils and fats react with oxygen and BECOME oxidised or TURN RANCID. This PROCESS is called rancidity.the substances that FORMED are called RANCID SUBSTANCE.

dation number of P changes from +1 to +3 and -3. Thus, the CHANGE in the OXIDATION number is 4. Hence, in the disproportionation reaction is, Equivalent massChange in the oxidation numberFormula mass=4M.

all are CORRECT ANSWER

(C) BECOME INFUSIBLE on MOLDING so cannot be REFUSED .

(C)neopreneNEOPRENE

So the CORRECT ANSWER is (C) POOR CONDUCTOR of electricity Explanation:They show excellent Electrical PROPERTIES.

The CORRECT ANSWER of this QUESTION is OPTION (d)

2.58 KG/ litreExplanation:density = mass/ VOLUME = 15.5/6.01 = 2.579 = 2.579 GM/ ML = 2.579 kg/ litre

>2FeO+Al>>2Fe+AlO2

Explanation:   a}  When non metal react with air, it forms non-metal OXIDE which is acidic in NATURE. Thus, when carbon(charcoal) burns in air, it forms an acidic oxide called carbon dioxide. The nature of the gas can be FOUND by adding water to the gas in the test tube. And then PUT some blue LITMUS solution in the jar.b}  It will turn blue litmus red. Thus, the gas is acidic in nature. Charcoal reacts with oxygen to form carbon dioxide gas

(B) =CALCIUM carbonateExplanation:

Diammine dichlorido COPPER (II)

Ethanol, also called ethyl alcohol, grain alcohol, or alcohol, a member of a class of organic compounds that are given the general name alcohols; its molecular FORMULA is C2H5OH. Ethanol is an important industrial chemical; it is USED as a solvent, in the synthesis of other organic CHEMICALS, and as an additive to automotive gasoline (forming a mixture known as a GASOHOL). Ethanol is also the intoxicating INGREDIENT of many alcoholic beverages such as beer, wine, and distilled spirits.

the ANS US polystyreneExplanation:FOLLOW me

A polymer that can be decomposed by bacteria is called a biodegradable polymer. ... The COMMON examples of aliphatic biodegradable polymers are polyglycolic acid(PGA), Polyhydroxy butyrate (PHB), Polyhydroxy butyrates-co-beta hydroxyl valerate( PHBV), Polycaprolactone(PCL), Nylon-2-nylon-6.

er !!ANSWER:(d) Nylon 6, 6Explanation:Thus, the polymer containing strong INTERMOLECULAR FORCES (e.g. hydrogen BONDING) is Nylon - 6,6.

a)BENZOYL PEROXIDE is CORRECT

cw-polyisoprene is the FINAL ANSWER

The ANSWER is LOW DENSITY POLYTHENE.

ill produce more severe BURNS than boiling water because steam has more heat energy than water DUE to its LATENT heat of vaporisation. Steam and boiling water can EXIST at varying temperatures but it is only correct to assume here that both are at the same temperature.

I don't KNOW this ANSWEREXPLANATION: OPTION d is the CORRECT ANSWER

If the hydrogen ion concentration is 0.00000001 moles per liter, this would be a solution with a pH of 8, which would be a basic solution. Here is how this was determined: By definition, using [H+] to represent the concentration of the hydrogen ions in moles per liter, p H = − l o g 10 [ H + ] If we take the equation for pH and fill it in with the H+ concentration, we can then CALCULATE the pH: p H = − l o g 10 [ H + ] p H = − l o g 10 0.00000001 p H = 8 Thus, the pH would be 8. Examples of solutions with pH 8 would be SEAWATER or baking soda solution. A solution with pH 8 is a base since the pH is above 7. Solutions with pH exactly 7 would be neutral, and those with a pH below 7 would be acidic, and those with a pH above 7 would be basic. Let's take a look at another example. Let's say that the hydrogen ion concentration of a solution was 0.001 moles per liter. What would the pH be for that solution? We can use the same equation, just filling in the hydrogen ion concentration with 0.001: p H = − l o g 10 [ H + ] p H = − l o g 10 0.001 p H = 3 This would be a very acidic solution, similar to what we might FIND in a carbonated beverage or in the gastric juices in our stomach.Explanation:

gaseous PARTICLES have HIGH kinetic energy and therefore diffuse FASTER . therefore OXYGEN will diffuse fasterExplanation:

Explanation:In order to make the agriculture SOIL fertile, EARTHWORMS and ORGANIC WASTES are included with the BASIC salts. The organic wastes and earthworm are highly acidic so they neutralize the salt.
