Answer:
F. 2NO + 02 —> 2NO
H. 4NH3 + 502 —> 4NO + 6H20
Explanation:
The law of conservation of mass states that matter can neither be created nor destroyed during a chemical reaction but can be convert from one form to another.
2NO + 02 —> 2NO
From the above, the total number of N on the left balance the total number on the right i.e 2 atoms of N on both side of the equation.
The total number of O on the left balance the total number on the right i.e 2 atoms of O on both side of the equation. This is certified by the law of conservation of mass.
4NH3 + 502 —> 4NO + 6H20
From the above, the total number of N on the left balance the total number on the right i.e 4 atoms of N on both side of the equation.
The total number of O on the left balance the total number on the right i.e 10 atoms of O on both side of the equation.
The total number of H on the left balance the total number on the right i.e 12 atoms of O on both side of the equation.
This is certified by the law of conservation of mass.
The rest equation did not conform to the law of conservation of mass as the atoms on the left side did not balance those on the right side
Answer: skeletal equation : 
The products are sodium nitrate and barium sulphate.
balanced equation : 
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
The skeletal equation is:
The balanced chemical equation is:
Ga₂O₃ + 2NaOH + 3H₂O = 2Na[Ga(OH)₄]
[Ga(OH)]⁻ + 3e⁻ = Ga + 4OH⁻
n(Ga)=It/(zF)
I=0.200 A
t=40.0 min=2400 s
z=3
F=96485.33 Kl/mol
n(Ga)=0.200*2400/(3*96485.33)=0.00166 =1.66*10⁻³ mol
<span>Carbon dioxide diffuses 20 times faster than oxygen gas
It is estimated, however, that the diffusing capacity of carbon dioxide is from 400 ml to 450 ml per minute under resting conditions and the diffusion capacity for oxygen under resting conditions is 21 ml per minute.</span>
