Answer:
1.0 × 10⁻⁵ mol/L
Explanation:
The concentration of a gas (C) in a liquid depends on its partial pressure (P), as expressed in Henry's law.
C = k × P
where,
k is the henry's law constant
When the partial pressure of the gas equilibrates at 3.0 × 10⁻⁴ atm, its concentration in the liquid is:
C = k × P
C = 3.4 × 10⁻² mol/L.atm × 3.0 × 10⁻⁴ atm
C = 1.0 × 10⁻⁵ mol/L
Answer:
is an aqueous reactant
is a liquid product
is a gaseous product
Explanation:
⇔
Hydrogen carbonate dissocates to form carbon dioxide and water. The acid (hydrogen carbonate) is in aqueous form and it dissociates to water (liquid) and carbon dioxide (a gas). It is also seen that the hydrogen carbonate is on the reactant side and it dissociates to produce water and carbon dioxide.
W<u> is an aqueous reactant</u> (a reactant undergoes changes in a chemical reaction
<u /><u> is a liquid product</u> (product refers to the species produced from chemical reaction)
<u /><u> is a gaseous product</u>

Based on atomic properties and structure:
- Isotopes have the same proton number(atomic number) but different neutron numbers.
- An atom of barium has 56 protons and 56 neutrons in order to maintain electrical neutrality.
- The mass number of an atom is determined by the sum of protons and neutrons.
<h3>What are isotopes?</h3>
Isotopes are atoms of an element having the same atomic number but different mass numbers.
The difference in mass number is dues to different neutron numbers.
However, because they have the same proton number, they are atoms of the same element.
Neutral atoms contains equal number of protons and electrons.
An atom of barium has 56 protons and 56 neutrons in order to maintain electrical neutrality.
The mass number of an atom is determined by the sum of protons and neutrons.
