Answer: 176 g N2O, 72 g H2O
Explanation:
1. 64g O2 * (1 mol O2)/(32 g O2) * (2 mol N2O)/(1 mol O2) * (44g N2O)/(1 mol N2O) = 176 g N2O
2. 32g CH4 * ( 1 mol CH4)/(16 g CH4) * (2 mol H2O)/(1 mol CH4) * (18 g H2O)/(1 mol H2O) = 72 g H2O
Answer:

Explanation:
Given that,
Mass of sample, m = 996.9 g
The change in temperature of the sample, 
Heat produced, Q = 62.9 calories = 263173.6 J
The heat released by a sample due to change in temperature is given by :

Where
c is the specific heat capacity
So,

So, the specific heat of ethanol is equal to
.
Answer:
12
Explanation:
The number of nearest neighbors (atoms that make contact) around each atom in a face-centered cubic lattice of a metal is
12.
This is because in a face centered cubic lattice ,there are ions found at the center of each of the six faces which are usually packed together and in close contact with one another.
Answer:
300 gr.
Explanation:
if 204gr/100gr=solubility, then according to the condition solubility=612/x.
It means, 204/100=612/x, where x=612*100/204=300 gr.
