A gas cylinder contains exactly 15 moles of oxygen gas (O2). How many molecules of oxygen are in the cylinder? 4.01 × 1022 molec
Semmy [17]
The answer is 9.03 × 10²⁴<span> molecules.

</span><span>Avogadro's number is the number of units (atoms, molecules) in 1 mole of substance.
Make the proportion.
</span><span>6.02 × 10²³ molecules per 1 mol
</span>x per 15 mol

6.02 × 10²³ molecules : 1 mol = x : 15 mol
x = 6.02 × 10²³ molecules * 15 mol * 1 mol
x = 90.3 × 10²³ molecules
x = 9.03 × 10 × 10²³ molecules
x = 9.03 × 10²³⁺¹ molecules
x = 9.03 × 10²⁴ molecules

Show how water can serve as a base by showing the chemical equation of water reacting with hydrochloric acid. g
goldfiish [28.3K]
So, water reacts with hydrochloric acid in the following formula

H2O + HCl —-> H3O+ + Cl-

We can visualize that when the two react, the hydrogen ions is taken on by the water molecule. This satisfies one of the definitions for a base

Bronsted acids = anything that donates a proton (H+ ion)

Bronsted bases = anything that accepts a proton (H+ ion)

So, as we can see, that is exactly what is happening. The Cl- and H+ detach and then the water takes on that extra H+.

H3O+ is what we call a hydronium ion
