The decreasing order of the mass of the molecules are:
Fe2O3>C6H14>CaCO>NO2
Explanation:
Let us calculate the atomic mass of the molecules given:
C6H14 Atomic mass of 1 carbon atom =12.01 amu
so, 6*12+1*14 Atomic mass of hydrogen=1.007
= 86 g/mol
Atomic mass of NO2
= 14+ (2*15.9)
= 14+ 31.8
= 45.8 g/mol
Atomic mass of Fe203
( 2*55.845)+ (3*15.9)
= 159.69 g/mol
Atomic mass of CaCO
40.07+12.0107+15.99
= 68.07g/mol
The decreasing order of the mass of the molecules are:
Fe2O3>C6H14>CaCO>NO2
Answer:
At equilibrium the rate of the forward reaction is equal to the rate of the backward reaction.
When the product of a reaction at equilibrium is increased the equilibrium will shift left or to the reactant side. As a result the excess product will get converted to reactant. This is in accordance to Le Chatelier's principle.
Le Chatelier's principle states that when a system is subjected to stress the equilibrium will shift in a direction to minimize effect of the stress.
Thus the products added to the system at equilibrium will make the equilibrium shift to the reactant side, the rate of the reverse or backward reaction will increase.

Mass is a newtons and it will not be weight because it’s mass
Answer:
58.94 mL
Explanation:
V1 = 48.3 mL V2 = v mL
T1 = 22 degree celsius OR 295 k T2 = 87 degree celsius OR 360 k
We will use the gas equation:
PV = nRT
Since the Pressure (p) , number of moles (n) and the universal gas constant(R) are all constants in this given scenario,
we can say that
V / T = k , (where k is a constant)
Since this is the first case,
V1 / T1 = k --------------------(1)
For case 2:
Since we have the same constants, the equation will be the same
V / T = k (where k is the same constant from before)
V2 / T2 = k (Since this is the second case) ------------------(2)
From (1) and (2):
V1 / T1 = V2 / T2
Now, replacing the variables with the given values
48.3 / 295 = v / 360
v = 48.3*360 / 295
v = 58.94 mL
Therefore, the final volume of the gas is 58.94 mL
