A gold nugget has a volume of 20.0 cm3 and its density is 19.3 g/cm3. What is the mass of the gold nugget?
salantis [7]
Density * Volume = Mass

Now we substitute the values in.

19.3 g/cm^3 + 20 cm^3 = 386 g

Mass = 386 g

A. Reaction with what gas in the atmosphere makes natural rain water slightly acidic? (2 points)
Vlada [557]

Answer:

See explanation

Explanation:

On the pH scale acidity ranges from pH values of 0-6.9. Natural rain water is slightly acidic due to the presence of carbon dioxide in the atmosphere which is an anhydride of carbonic acid.

CO2(g) + H2O(l) -------> H2CO3(aq)

B. The equations that turn sulfur to sulfuric acid are;

S(l) + O2(g) -----> SO2(g)

2SO2(l) + O2(g) -----> 2SO3(g)

SO3(g) + H2SO4(l) -----> H2S2O7(l)

H2S2O7(l) + H2O(l) ----> 2H2SO4(l)

-

At pH 6, H^+ concentration = 1 * 10^-6 M

At pH 2, H^+ concentration = 1 * 10^-2 M

Hence;

1 * 10^-2/1 * 10^-6

= 10^4 times more acidic
