Answer:
We actually output other gases like methane lol
Explanation:
Well since most of the air we breathe is made up of nitrogen we also breathe out nitrogen

<h2>T
he mass of a liquid substance affected after it boils : C it stays the same</h2>
Explanation:
Matter
Anything that occupies space and has mass .
The states of matter are :
Solids
Liquids
gases
Interconversion of state of matter
Solid ------liquid -----------Gas
(on heating ) (on heating )
- One state can be changed in to another by changing the condition of temperature , pressure etc .
- When liquid is boiled , it gets converted to gaseous form on heating .The heat supplied to change the state of matter is called latent heat .
- This latent heat , just helps in increasing the spaces between particles and decreasing the forces between them Hence we can say that it helps in changing the state .But it doesn't change the mass .Hence mass of substance remains the same .
- Similarly , gas -----> liquid -----> solid
(on cooling ) (on cooling )
It stays a solid at room temperature . hope this helps you ☺
First we divide the masses by molar masses:
0.62 g carbon / (12.01 g/mol carbon) = 0.0516 mol C
0.10 g hydrogen / (1.01 g/mol H) = 0.099 mol H
0.28 g oxygen / (14 g/mol O) = 0.02 mol O
Since O has the smallest amount, we divide the other values by it:
0.0516 mol C / 0.02 mol O = 2.58 ~ 2.5
0.099 mol H / 0.02 mol O = 4.95 ~ 5
Therefore we have a ratio of C2.5, H5, and O. Since an empirical formula must only contain integers, we multiply everything by two to get:
C5H10O2
