Answer:
The Mole-Volume Relationship: Avogadro's Law. A plot of the effect of temperature on the volume of a gas at constant pressure shows that the volume of a gas is directly proportional to the number of moles of that gas. This is stated as Avogadro's law.

Answer:
C
Explanation:
it breaks down a simple sugar into a type of energy their cells can use
Answer:
Assume that 100 grams of C2H4 is present. This means that there are 85.7 grams of carbon and 14.3 grams of hydrogen.
Convert these weights to moles of each element:
85.7 grams carbon/12 grams per mole = 7 moles of carbon.
14.3 grams hydrogen/1 gram per mole = 14 moles of hydrogen.
Divide by the lowest number of moles to obtain one mole of carbon and two moles of hydrogen.
Since we know that there cannot be a stable CH2 molecule, multiply by two and you have C2H4 which is ethylene - a known molecule.
The secret is to convert the percentages to moles and find the ration of the constituents.
Answer:
Kj/mol
Its an endothermic reaction
Explanation:
Enthalpy can be evaluated by using following formula -
where
q is the enthalpy or change in internal energy
m is the mass in kg
c is the specific heat
and 
is the change in temperature
Mass of HCl is equal to 
g/mol
or
Mass of HCl is equal to 
Kg/mol
Substituting the given values in above equation, we get-
Kj/mol
Enthalpy is positive thus it is an endothermic reaction
