When molten material hardens and cools, what type of rock is formed?

B

Gemiola [76]

Answer: 1. magnesium hydroxide + sulfuric acid = magnesium sulphate + water

2. calcium hydroxide + hydrochloric acid = calcium chloride + water

3. lead hydroxide + nitric acid = lead nitrate + water

4. sodium hydroxide + sulfuric acid = sodium sulphate + water

5. potassium hydroxide + citric acid = potassium citrate + water

6. silver hydroxide + hydrochloric acid = silver chloride + water

7. aluminium hydroxide + phosphoric acid = aluminium phosphate + water

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 balanced chemical equations are :

1. magnesium hydroxide + sulfuric acid = magnesium sulphate + water

$Mg(OH)_2(aq)+H_2SO_4(aq)\rightarrow MgSO_4(aq)+2H_2O(l)$

2. calcium hydroxide + hydrochloric acid = calcium chloride + water

$Ca(OH)_2(aq)+2HCl(aq)\rightarrow CaCl_2(aq)+2H_2O(l)$

3. lead hydroxide + nitric acid = lead nitrate + water

$Pb(OH)_2(aq)+2HNO_3(aq)\rightarrow Pb(NO_3)_2(aq)+2H_2O(aq)$

4. sodium hydroxide + sulfuric acid = sodium sulphate + water

$NaOH(aq)+H_2SO_4(aq)\rightarrow Na_2SO_4(aq)+H_2O(l)$

5. potassium hydroxide + citric acid = potassium citrate + water

$KOH(aq)+C_6H_8O_7(aq)\rightarrow C_6H_7O_7K(aq)+H_2O(l)$

6. silver hydroxide + hydrochloric acid = silver chloride + water

$AgOH(aq)+HCl(aq)\rightarrow AgCl(s)+H_2O(l)$

7. aluminium hydroxide + phosphoric acid = aluminium phosphate + water

$Al(OH)_3(aq)+H_3PO_4(aq)\rightarrow AlPO_4(aq)+3H_2O(l)$

Hydrochloric acid and sodium hydroxide can be combined to form sodium chloride and water. Which best explains the reaction? The

Bogdan [553]

Answer:

The statement "The total mass of hydrochloric acid and sodium hydroxide will result in the same total mass of sodium chloride and water." is true due to the Law of Conservation of Mass which states that matter cannot be created nor destroyed.

Why do you move the .0100 - x to the left side of the equal sign?

dlinn [17]

Because negatives are on the left and positives are on the right , if it was .0100 +x it would move to the right since +x implies that the x is positive.

saw5 [17]

The area where she is flying in windless conditions along the equator is called doldrums. Doldrums is a windless zone at the equator caused by warm rising air. The zone experience bands of showers and storms due to the hot air that rises and cools.
