Write balanced ionic equations and net ionic equations for the following reactions.
Kipish [7]
The ionic equation will be: 
<span>Mg2+(aq) + 2OH-(aq) + 2H+(aq) + 2NO3-(aq) → Mg2+(aq) + 2NO3-(aq) + 2H2O(l) 
</span>And the net ionic: 
<span>2OH-(aq) + 2H+(aq) → 2H2O(l) 
</span>a Balanced equation would be:
<span>Mg(OH)2(aq) + 2HNO3(aq) → Mg(NO3)2 (aq) + 2H2O(l) 
</span>Now  thsi si so because of the standard equation which is base plus acid=Salt plus water. We need to have in mindo that Mg(OH)2 is sparingly soluble in water and is aqueous mos of the times

Alcohol is poured into a beaker that contains 2% saltwater. Which are the solutes in the new solution?
Vadim26 [7]
A 2% saltwater is a dilute solution in which the solvent is water and the solute is salt. The solvent is the component of the solution which comprise a large percentage while the solute comprise the smaller part. When alcohol is added, the solute still is salt and the solvent is the mixture of water and alcohol.

Calculate the amount of heat energy required to convert 55.0 g of water at 62.5°C to steam at 124.0°C. (Cwater = 4.18 J/g°C; Cst
Grace [21]

Answer:

= 135,647.65 Joules or 135.65 kJ

Explanation:

Heat require to raise the temperature of 55 g water from 62.5°C  to 124.0°C will be calculated in steps;

Step 1; heat required to raise water from 62.5°C to 100 °C

Heat = 55 g × 4.18 J/g°C × (100 -62.5)

        = 8,621.25 Joules

Step 2; Heat required to convert water to steam without change in temperature;

Heat = moles × Molar Latent heat of vaporization.

        = (55g / 18 g/mol)× 4.07 ✕ 104 J/mol

        = 12.436 × 10^4 Joules

Step 3: Heat required to raise the temperature of steam from 100°C to 124 °C.

Heat = mass × specific heat capacity × ΔT

        = 55 g × 2.02 J/g°C × (124-100)

        = 2,666.4 Joules

Therefore; total amount of heat required is;

 = 8,621.25 J + 124360 J + 2,666.4 J

<u> = 135,647.65 Joules or 135.65 kJ</u>
