mass h
<h3>
</h3>
Explanation:
molar mass is equal to number of mass over moles we take 14.19 over17 molar mass of ammammonium equals 0.8347 incase of moles. 1H=1Nh3 ,so. n.H=0.8347 Mr=2 ,M.H=? Mr=m/n. 0.8347x2=1.669grams
This is held together by the charges of anions and cations that are attracted to each other, which is the reason why crystal lattice is being formed beside the fct that it has tightly packed network. The crystal lattice are the crystals which has an arrangement that could be describe with its three dimensional feature.
Answer:
E. The ratio of [HNO2] / [NO2-] will increase
D. The pH will decrease.
Explanation:
Nitrous acid ( HNO₂ ) is a weak acid and NaNO₂ is its salt . The mixture makes a buffer solution .
pH = pka + log [ salt] / [ Acid ]
= 3.4 + log .32 / .42
= 3.4 - .118
= 3.282 .
Now .16 moles of nitric acid is added which will react with salt to form acid
HNO₃ + NaNO₂ = HNO₂ + NaNO₃
concentration of nitrous acid will be increased and concentration of sodium nitrite ( salt will decrease )
concentration of nitrous acid = .42 + .16 = .58 M
concentration of salt = .32 - .16 = .16 M
ratio of [HNO₂ ] / NO₂⁻]
= .42 / .32 = 1.3125
ratio of [HNO₂ ] / NO₂⁻] after reaction
= .42 + .16 / .32 - .16
= 58 / 16
= 3.625 .
ratio will increase.
Option E is the answer .
pH after reaction
= 3.4 + log .16 / .58
= 2.84
pH will decrease.
Answer:
The ice cube would sink, as the density of ice is greater than that of water. Hope this helps! =) pls give me brainilest! =)
Answer:
More reactants will be produced
Explanation:
Le Chatelier's principle; adding additional product or reactant will move the equilibrium left or right to compensate and come back to equilibrium
By adding more product to your system at equilibrium, the equilibrium will shift towards reactants, more reactants will be produced
