The amount of grams of hydrogen that are in the water sample is;
3.985 g
<h3>Avogadro's number</h3>
We are given that;
Number of moles of oxygen in a sample of water = 12 × 10²³
- Now, the chemical formula of a molecule of water is H₂O. This means that for every 1 atom or molecule of oxygen, there must be 2 hydrogen atoms or molecules present.
Since Number of moles of oxygen in the sample is 12 × 10²³, then number of moles of hydrogen will be twice that = 2 × 12 × 10²³ = 24 × 10²³ moles
Now, molar mass of hydrogen is 1 g/mol and we know that;
Molar mass = Avogadro's number(6.023 × 10²³) moles
Thus;
6.023 × 10²³ moles = 1 g/mol
Thus; 24 × 10²³ moles of hydrogen = ( 24 × 10²³ × 1)/(6.023 × 10²³)
⇒ 3.985 g

Answer:
The answer is A.) Tranquil describes Torres as calm, which is the opposite of how the narrator feels.
Explanation:
The effect of wildfires on biodiversity is temporary decrease, but long-term increase.
The effect of wildfires also known as forest fire on biodiversity is wildfires break down organic material faster than decomposition, thus renewing soil nutrients more quickly.
Effect of wildfires is that the loss of biodiversity and extinction of plants and animals. Loss of wildlife habitat and depletion of wildlife. Loss of natural regeneration and reduction in forest cover, warming.
The smoke from wildfires causes pollution and is bad for your health regardless of where you reside. Wildfires release harmful pollutants including particulate and toxin gases like carbon monoxide, nitrogen oxides, and non-methane organic compounds into the atmosphere, wildfires have many acute and chronic effects on human health too.

The number of ways the skaters can finish the competition is 40,320 ways
The different ways 3 of the skaters finish first, second and third is 56 ways
Given the following
- Number of skaters featured = 8 skaters
If the skaters finish the competition, the number of different ways the skaters finish the competition is expressed as:
8! = 8*7*6*5*4*3*2
8! = 56*30*24
8! = 40,320.
The number of ways the skaters can finish the competition is 40,320 ways
If 3 of the skaters finish first, second and third, the number of ways this can be done is given as:
8C3 = 8!/(8-3)!3!
8C3 = 8!/5!3!
8C3 = 8*7*6*5!/5!3!
8C3 = 56 ways
Hence the different ways 3 of the skaters finish first, second and third is 56 ways
