<span>The natural source of acidity in rain water is all of the above. This is due to presence and abundance of carbon dioxide, nitrogen oxide, and sulfur dioxide in the atmosphere that can dissolve in rain water. Unpolluted rain water is made acidic due to CO2 and H2O in the air that forms carbonic acid.

Nitrogen oxide is mainly present due to the nitrogen fixation caused by lightning, while sulfur dioxide is mainly present due to volcanic eruptions. Other sources such as human activity can also contribute to acid rain. </span>

What are the empirical formulas of a) ethylene glycol, a radiator antifreeze, molecular formula C2H6O2 b) peroxodisulfuric acid,

Temka [501]

<h2>The answers are $CH_3O$ and $HSO_4$ </h2>

Explanation:

Given -

a) The molecular formula of ethylene glycol -

$C_2H_6O_2$

∴ The empirical formula of ethylene glycol will be -

$CH_3O$

Given -

b) The molecular formula of per-oxo-disulfuric acid (a compound used in bleaching agents) -

$H_2S_2O_8$

∴ The empirical formula of per-oxo-disulfuric acid will be -

$HSO_4$

Hence, the answers are $CH_3O$ and $HSO_4$ .

Danny sails a boat downstream. The wind pushes the boat along at 21 km/hr. The current runs downstream at 15 km/hr. What is the

deff fn [24]

Answer: D) 36.0 km/hr, downstream

Explanation:

For downstream motion of the boat, the actual velocity of the boat is the sum of velocity of the water current and the velocity of the boat due to pushed by wind.

Velocity of water current, v = 15 km/h

Velocity of the boat going downstream, u = 21 km/h

Actual velocity of the boat = v'

v' = v + u

⇒v' = 15 km/h + 21 km/h

⇒u = 21 km/h +15 km/h = 36.0 km/h downstream

Thus, the correct answer is option D.
