Answer : No
Explanation: The chemical compounds are formed from their elements in a fixed ratio of masses, for example, in water (H2O), always Hydrogen and oxygen are combined in 1:8 by mass, i.e. with 1 g Hydrogen the Oxygen is 8 g, with 2 g Hydrogen the oxygen would be 16 g. So, there is a fixed ratio by masses.
If we were to react hydrogen with oxygen then it would again combine in 1:8 always. If we use 1 g Hydrogen with 10 g oxygen, all of the 1 g hydrogen would still react with 8 g oxygen and the third chemical formed water is 1+8 = 9 g and not 1+10 =11 g.
So, its generally not possible.
Also not all chemical reactions proceed to completion, i.e. there are always few reactant molecules left unreacted, for example the burning of candle is a chemical process where some of the lower part of wax is left behind. so, not always all of the reactants get converted to products.
Only if we have a special case where reactants react completely and you chose the masses of reactant exactly in the ratio they combine, then only the third chemica will have mass exactly equal to the sum of masses of all reactants taken at the start, like if we take hydogen 2g and oxygen 16 g then water is 2+16 = 18, because 2 will combine exactly with 16.
Hope the answer helps.
Answer:
The final pressure of a gas is inversely proportional to the volume change and directly proportional to temperature
Explanation:
Given
Required
Interpret
Multiply both sides by T1
Divide both sides by V1
This can be rewritten as:
In the above expression; k is a constant of proportionality.
So, the equation can be written as variation as follows:
To interpret:
<em>P varies directly to T (the numerator) and inversely to V (the denominator).</em>

Answer:
For Covalent bonds, atoms tend to share their electrons with each other to satisfy the Octet Rule. It requires 8 electrons because that is the amount of electrons needed to fill a s- and p- orbital (electron configuration); also known as a noble gas configuration
Explanation:
Answer:
Intensive properties do not depend on the quantity of matter. Examples include density, state of matter, and temperature. Extensive properties do depend on sample size. Examples include volume, mass, and size.
