Answer : The amount of carbon dioxide produced is, 197.12 grams.
Explanation : Given,
Moles of ethanol = 2.24 mole
Molar mass of carbon dioxide = 44 g/mole
The balanced chemical reaction will be,

First we have to calculate the moles carbon dioxide.
From the balanced chemical reaction, we conclude that
As, 1 mole of ethanol react to give 2 moles of carbon dioxide
So, 2.24 mole of ethanol react to give
moles of carbon dioxide
Now we have to calculate the mass of carbon dioxide.


Therefore, the amount of carbon dioxide produced is 197.12 grams.
Answer:
0.59 g
Explanation:
The reaction at the first cathode;
Ag^+(aq) + e -----> Ag
if Q = It = 1.5 * 10 * 60 = 900C
According to Faraday's second law of electolysis; if we pass the same quantity of electricity through different electrolytes, the mass of substances deposited on each cathode is proportional to the equivalent weights.
Equivalent weight E = Atomic mass/valency
For Ag = 108/1 = 108
For Ni = 59/2 = 29.5
Hence
Let m1 = mass of Ag deposited =2.16
Let m2 = mass of Ni deposited
Let E1 = equivalent weight of Ag
Let E2 = equivalent weight of Ni
m1/m2 = E1/E2
2.16/m2 = 108/29.5
m2 = 2.16 * 29.5/108
m2 = 0.59 g
Use the state equation for ideal gases: pV = nRT
Data:
V = 88.89 liter
n = 17 mol
T = 67 + 273.15 = 340.15 K
R = 0.0821 atm * liter / (K*mol)
=> p = nRT / V = 17 mol * 0.0821 (atm*liter / K*mol) * 340.15 K / 88.89 liter
p = 5.34 atm
Answer: p = 5.34 atm
Answer:
Option A. Gases are compressible and have a variable shape.
Explanation:
From the knowledge of kinetic theory of matter, we understood that the force of attraction between gases molecules are negligible and this makes the gas molecules to be far apart. With this character, they can easily be compressed. Since the molecules of gas are far apart, they have no fixed shape, but tends to assume the shape of the container they are placed.
