Answer: This a redoc reaction.

The total ionic equation in separated aqueous solution will be,

2H^+(aq)+2O^{-}(aq)+Mg^{2+}(aq)+SO_3^{2-}(aq)\rightarrow Mg^{2+}(aq)+SO_4^{2-}(aq)+H_2O(l)

Explanation :

The given reaction is a redox reaction in which the oxygen shows reduction and sulfur shows oxidation reaction.

In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The given balanced ionic equation will be,

H_2O_2(aq)+MgSO_3(aq)\rightarrow MgSO_4(aq)+H_2O(l)

The total ionic equation in separated aqueous solution will be,

2H^+(aq)+2O^{-}(aq)+Mg^{2+}(aq)+SO_3^{2-}(aq)\rightarrow Mg^{2+}(aq)+SO_4^{2-}(aq)+H_2O(l)

why would it not be necessary to heat the air in the balloon as much if the air outside the balloon is colder?
RUDIKE [14]

Hot-air balloons float because the air caught inside the balloon is heated up by a burner, making it less dense than the air outside. As the burner heats the air, it expands and some of the air escapes; that's what makes it less dense

How many grams of zinc phosphate are formed when 48.1 mL of 2.18 M zinc nitrate reacts with excess potassium phosphate?
Roman55 [17]

Answer:

15.4 g of Zn₃(PO₄)₂ are produced

Explanation:

Given data:

Mass of zinc phosphate formed = ?

Volume of zinc nitrate = 48.1 mL (0.05 L)

Molarity of zinc nitrate = 2.18 M

Solution:

Chemical equation:

3Zn(NO₃)₂ + 2K₃PO₄  →   Zn₃(PO₄)₂ + 6KNO₃

Moles of  zinc nitrate:

Molarity = number of moles / volume in litter

Number of moles =  2.18 M × 0.05 L

Number of moles = 0.109 mol

Now we will compare the moles of zinc phosphate with zinc nitrate from balanced chemical equation:

                     Zn(NO₃)₂           :            Zn₃(PO₄)₂

                         3                    :                 1

                       0.109               :               1/3×0.109 = 0.04 mol

0.04 moles of Zn₃(PO₄)₂ are produced.

Mass of Zn₃(PO₄)₂:

Mass = number of moles × molar mass

Mass = 0.04 mol × 386.1 g/mol

Mass = 15.4 g
