Why is rain water always somewhat acidic?

2 answers:

8 0

Answer: a. Because the carbon dioxide in the air mixes with it to form carbonic acid and d. Because sulfur dioxide released from burning petroleum mixes with it to form sulfuric acid.

Explanation:

$CO_2+H_2O\rightarrow H_2CO_3$

$SO_2+H_2O\rightarrow H_2SO_3$ , which oxides in air to form $H_2SO_4$

Thus carbonic acid $H_2CO_3$ and sulphuric acid $H_2SO_4$ mixes with rain to form acid rain.

Nitrogen monoxide $NO$ and not nitrous oxide $N_2O$ forms nitric acid.

How much heat, in joules and in calories, must be added to a 75.0Â–g iron block with a specific heat of 0.449 j/g Â°c to increas

lianna [129]

Answer:

$Q=50,849.25J\\\\Q=12,153.3cal$

Explanation:

Hello!

In this case, given the mass, temperature change and specific heat, it is possible to compute the required heat in joules as shown below:

$Q=mC(T_2-T_1)\\\\Q=75.0g*0.449\frac{J}{g\°C}(1535\°C-25\°C)\\\\Q=50,849.25J$

Now, since 1 cal =4.184 J, this result in calories is:

$Q=50,849.25J*\frac{1cal}{4.184J}\\\\Q=12,153.3cal$

Best regards!
