<h3><u>Answer;</u></h3>
3.4 kJ
<h3><u>Explanation</u>;</h3>
Taking the mass of water as 10.0 g
Moles of water = Mass /molar mass
Moles of water in 10.0 g;
= 10g H2O x 1mol/18g
=0.56mol
But, 1 mole of water = 6.01 kJ
Hence;
6.01kJ/1mol H2O= x kJ/.56mol,
x = <u>3.4kJ</u>

Joshua Tree suffers from air pollution and smog blowing into the park. Increased warming from climate change worsens the visibility from smog and air pollution, due to the chemistry of how smog reacts to heat.
Answer:
Explanation:
Hello there!
In this case, according to the given information derived from the combustion analysis, it turns out possible for us to realize that all the carbon comes from the CO2 and all the hydrogen from the H2O, it means we can calculate their moles in the vitamin C as shown below:
Next, we calculate the grams and moles of oxygen from the grams of C and H in the sample:
Then, we divide the moles of C, H, O by 0.0165 as the fewest moles in order to calculate the correct mole ratios:
Finally, we turn them into whole number by multiplying by 3 so that the empirical formula is:

The name of the acid that is formed when hydrogen sulfide is dissolved in water would be hydrosulfuric acid. It has the same chemical formula as hydrogen sulfide which is H2S. It is classified as a weak acid which partially ionizes into hydrogen sulfide ions and hydronium ions. It is a very toxic substance and is distinguished by its strong odor which is compared to an egg that is rotting. It can be found in high concentrations in the crust of the Earth, in volcanic emissions and in many fossil fuels. To produce this acid, the gas hydrogen sulfide is dissolved into the water. However, this acid is not produced since it does not have any industrial application.
