Pavel [41]

Answer:

ΔH = +26.08 kJ/mol

Explanation:

The change in enthalpy (ΔH) is given in J/mol, and can be calculated for  dissolution by the equation:

ΔH = m(water)*Cp*ΔT/n(solute)

The mass of water is the density multiplied by the volume

m = 1g/mL * 25.0mL = 25.0 g

The number of the moles is the mass divided by the molar mass. Knowing the molar masses of the elements:

N = 14 g/mol x 2 = 28

H = 1 g/mol x 4 = 4

O = 16 g/mol x 3 = 48

NH₄NO₃ = 80 g/mol

n = 1.25/80 = 0.015625 mol

So,  

ΔH = 25*4.18*(25.8 - 21.9)/0.015625

ΔH = 26,083.2 J/mol

ΔH = +26.08 kJ/mol

Insoluble molecular compounds break apart into atoms when added to water.<br> True<br> O False
masha68 [24]

Answer:

False.

This is false because, no chemical reaction could possibly happen.

But in case of sodium it is highly reactive with water.......... so there will be a chemical reaction.

but as sodium is not a insoluble molecular compound this is not applicable to the situation.

A pool owner adds a compound containing chlorine to the pool to disinfect it. However, too much of the compound is added. As a r
MrMuchimi

Answer: He could add a base to the pool to neutralize the acid.

Explanation:

Chlorine is used to disinfect the pools as it produces hypochlorous acid in water. This hypochlorous acid is unstable and gives hydrochloric acid and nascent oxygen which is used to disinfect.

Cl_2+H_2O\rightarrow HOCl

HOCl\rightarrow HCl+O

The excess acid is neutralized by adding base which produces salt and water and thus decrease the acidity.

Acid+Base\rightarrow Salt+water

Adding more acid would increase the acidity further.
