NARA [144]3 years ago
7 0

Answer: Magnesium hydroxide, Mg(OH)2

Explanation:

2HC2H3O2(aq) + Mg(OH)2(aq) → Mg(C2H2O2)2(aq) + 2H2O(l)

Acid + base → Salt + Water.

The equation above is an example of an acid-base reaction where the acid, aqeous 2HC2H3O2 reacts completely with an appropriate amount of the base, aqueous Mg(OH)2 to produce salt, aqueous Mg(C2H2O2)2 and water, liquid H2O only.

This acid-base reaction is also known as neutralization reaction.

The pH of a solution is measured as 4.5. What is the hydrogen ion concentration of the solution?
Bond [772]

Answer:

[H⁺] =  3.16 × 10⁻⁵ mol/L

Explanation:

Given data:

pH of solution = 4.5

Hydrogen ion concentration = ?

Solution;

pH = -log [H⁺]

we will rearrange this formula:

[H⁺] =  10∧-pH

[H⁺] = 10⁻⁴°⁵

[H⁺] =  3.16 × 10⁻⁵ mol/L

How many liters of hydrogen gas are formed from the complete reaction of 1.04 mol of C? Assume that the hydrogen gas is collecte
Alisiya [41]

The volume is 2.23 liters of hydrogen gas.

<u>Explanation</u>:

                  moles of C = grams / molecular mass of C

                                     = 1.04 g / 12.011 g/mol.

                                     = 0.086

        The ratio between C and H2 is 1 : 1

                 moles H2 = 0.086

                               V = nRT / p

                                  = 0.086 x 0.08206 x 316 K / 1.0 atm

                              V  = 2.23 L.
