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

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

Find a total pressure of the gas mixture that contains forecast is with partial pressure of 5.00 kPa, 4.56 kPa 356 kPa and 678KP

Orlov [11]

Answer: 1044 kPa

Explanation: To find the total pressure of a system, you add up all the partial pressures. 5.00+4.56+356+678=1043.56, but since you need to account for significant figures it is 1044.

In addition, the amount of significant figures is the number with the smallest amount of decimal places. In this case you have no decimal places, since 356 and 678 have no decimal places. Remember that for the numbers 0-4 you round down and 5-9 you round up.
