Acid rain has a higher than normal pH. a. True b. False

Chemistry

False.  Since acids are proton donors and pH=-log[H⁺], acids lower the pH of the solution that they are put into.  Therefore acid rain will have a lower pH than normal.
I hope this helps.

How much energy must be absorbed by 45.0g of water to increase its temperature from 83 0°C to 303.0°C?
mrs_skeptik [129]

Answer: There will be 41382 J energy must be absorbed by 45.0g of water to increase its temperature from 83.0^{o}C to 303.0^{o}C.

Explanation:

Given: Mass = 45.0 g

Initial temperature = 83.0^{o}C

Final temperature = 303.0^{o}C

Formula used to calculate heat energy is as follows.

q = m \times C \times (T_{2} - T_{1})

where,

q = heat energy

m = mass of substance

C = specific heat = 4.18 J/g^{o}C (here, for water)

T_{1} = initial temperature

T_{2} = final temperature

Substitute the values into above formula as follows.

q = m \times C \times (T_{2} - T_{1})\\= 45.0 g \times 4.18 J/g^{o}C \times (303.0 - 83.0)^{o}C\\= 41382 J

Thus, we can conclude that there will be 41382 J energy must be absorbed by 45.0g of water to increase its temperature from 83.0^{o}C to 303.0^{o}C.

A solution of H2SO4 (90.08 g/mol) has 785.6 g of H2SO4 and 359 g of H2O. What is the molal concentration (molality)?
tekilochka [14]

The molality of H₂SO₄ solution is 24.2 m.

<u>Explanation:</u>

We need to find the molality of sulfuric acid.

Mass of sulfuric acid = 785.6 g

Mass of water = 359 g

We have to find the moles of H₂SO₄ by using its mass and molar mass as,

Moles of H₂SO₄ = $\frac{785.6g}{90.08 g/mol}

                         = 8.7 moles

Mass of the solution in kg =$\frac{359}{1000} =  0.359 kg

Molality = $\frac{moles}{solvent (kg)}

           = $\frac{8.7 mol }{0.359 kg}\\

          = 24.2 m

So molality of the H₂SO₄ solution is 24.2 m.
