Answer:
2) less
3) more
4) higher
5) slower (I’m not sure about this one sorry)
6) decreases
1) Molar mass C5H12= 5*12 +1 *12=60+12=72 g/mol
2) 40g C5H12 * 1 mol C5H12/72 g C5H12 = 40/72 mol C5H12
3) C5H12 + 8O2 ------> 5CO2 + 6H2O
by reaction 1 mol 8 mol
from problem 40/72 mol x mol
x=(40/72) * 8/1=(40*8)/72=(40)/9 mol O2
4) M(O2)=2*16 g/mol =32 g/mol
5) (40)/9 mol O2 *(32 g O2/ 1 mol )=(40 * 32)/9 =142.2 g O2
Answer:
The rate of the forward reaction and the rate of the reverse reaction are equal
The concentrations of the reactants and products no longer change.
Explanation:
The equilibrium state is a state of rest or motion of chemical system.
These are some of the condition for dynamic equilibrium of a system:
the systems must be involved in reversible chemical reactions.
the rate of forward reaction is equal to that of the reverse process.
the system offers no resistance to any change in any of the factors.
there is no change in concentration of each of the species in equilibrium with respect to time.
We can see that a system in equilibrium clearly identifies with the chosen options.
The number of protons in the nucleus of the atom is equal to the atomic number. So the number of atomic number is equal to the number of protons. hope it helped (:
