Atoms are the thing that make up molecules and compounds. Molecules contain two or more atoms and are held together by covalent bonds
The reaction of sodium bromide with chlorine gas is Cl₂(aq) + 2Na + 2Br? 2Na + 2Cl⁻ + Br²(aq).
<h3>What is sodium bromide?</h3>
Sodium bromide is an inorganic compound, white, crystalline with high melting point.
The reaction between halogens is redox reaction
Oxidation – 2Br⁻ ? Br₂ + 2e⁻ loss of electron.
Reduction – Cl₂ + 2e⁻ ? 2Cl⁻ gains of electron.
Thus, the correct option is Cl₂(aq) + 2Na + 2Br? 2Na + 2Cl⁻ + Br²(aq).

Answer:
[H+] =5.62*10⁻¹⁰
Explanation:
pH = 9.25
The formula to find pH of a solution is
pH = -Log[H+]
9.25 = -Log[H+]
Take the anti log of both sides
[H+] = 10⁻⁹.²⁵
[H+] = 5.62*10⁻¹⁰
The concentration of Lithium Hydroxide is 5.62*10⁻¹⁰
Answer:
3L
Explanation:
The following data were obtained from the question:
V1 (original volume) = 6L
P1 (original pressure) = 1.5 atm
P2 (new pressure) = 2 x P1 ( since the new pressure is doubled)
P2 = 2 x 1.5
P2 = 3 atm
V2 (new volume) =?
Using the Boyle's law equation P1V1 = P2V2, the new volume can be obtain as follow:
P1V1 = P2V2
1.5 x 6 = 3 x V2
Divide both side by 3
V2 = (1.5 x 6)/3
V2 = 3L
From our calculations, the new volume will be half the original volume and this will be 3L
