HCl + NaOH → NaCl + H2O.
H2SO4 + 2 NaOH → Na2SO4 + H2O.
HCl + NH3 → NH4Cl + H2O.
HCN + NaOH → NaCN + H2O.
Explanation:
Hey there!
Molarity = 4.8/850 x 1000 =5.647mol/lit or 5.65M
Hope this helps you dear :)
Have a good day :)
Answer:
Reduction
Explanation:
Reduction:
Reduction involve the gain of electron and oxidation number is decreased.
Mn⁺⁷ +3e⁻ → Mn⁴⁺
Mn gets three electrons , its oxidation state reduced from +7 to +4 so Mn gets reduced.
Examples:
Consider the following reactions.
4KI + 2CuCl₂ → 2CuI + I₂ + 4KCl
the oxidation state of copper is changed from +2 to +1 so copper get reduced.
CO + H₂O → CO₂ + H₂
the oxidation state of carbon is +2 on reactant side and on product side it becomes +4 so carbon get oxidized.
H₂S + 2NaOH → Na₂S + 2H₂O
The oxidation sate of sulfur is -2 on reactant side and in product side it is also -2 so it neither oxidized nor reduced.
Answer:
The answer is
<h2>5.0 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 35 g
volume = 7 cm³
The density is

We have the final answer as
<h3>5.0 g/cm³</h3>
