Answer:

Explanation:
= Initial pressure = 931 torr = 
= Final pressure = 113 kPa
= Initial volume = 350 mL
= Final volume
From the Boyle's law we have

The volume the gas would occupy is
.

Answer:
0.225 mol = 0.23 mol to 2 significant figures
Explanation:
Calculate the moles of oxygen needed to produce 0.090 mol of water
The equation of the reaction is given as;
2 C2H2 + 5 O2 --> 4 CO2 + 2 H2O
From the equation of the reaction;
5 mol of O2 produces 2 mol of H2O
x mol of O2 produces 0.090 mol of H2O
5 = 2
x = 0.090
x = 0.090 * 5 / 2
x = 0.225 mol
Answer:
True
Explanation:
The more of each substanse that you add to the bag will cause it to produce faster and more gas.
Answer:-
b. compound b will show an nh absorption while compound a will not.
Explanation:-
For compound B CH3CH2CH2NH2 there are two N-H bonds present. So it will show NH absorption.
But in compound A CH3CH2CH2N(CH3)2 there are no N-H bonds. So it will not show NH absorption.
