Explanation:
Pressure is the constant in Charles' law. If the pressure is constant, then this law upholds as being true.
Answer:
B. increase the distance between the objects
Explanation:
A) increase the mass of one of the objects
Answer:
The formula would be: C₆H₈O
Explanation:
The mass of carbon dioxide formed = 627.4 mg
The percentage of carbon in the sample would be:
% carbon =
Where
44 is the molar mass of carbon dioxide.
The percentage of hydrogen in the sample would be:
% Hydrogen =
Rest will be oxygen = 100 -[74.92+8.33]=16.75
Let us calculate the moles of each of the elements present:
moles of carbon =
moles of hydrogen =
moles of oxygen =
The mole ration of carbon, hydrogen and oxygen = C:H:O = 6 : 8 : 1
so the formula would be:
C₆H₈O
