Answer:
20L is the new volume
Explanation:
In this case, moles and T° from the gas remain constant. This is the formula we must apply, to solve this:
P₁ . V₁ = P₂ . V₂
5 atm . 10 L = P₂ . 2.5L
P₂ = (5 atm . 10 L) / 2.5L →20L
Hello!
The answer is Evaporation
When you add heat to water, it boils, releasing gas into the air. This is called Evaporation. The water changes from a liquid to a gas.
Hope this helped!
Answer:
Option A = 17.03 g/mol
Explanation:
Given data:
Atomic mass of nitrogen = 14.01 g/mol
Atomic mass of hydrogen = 1.008 g/mol
Molecular mass of NH₃ = ?
Solution:
Molecular mass of NH₃ = (14.01 g/mol × 1) + (1.008 g/mol × 3)
Molecular mass of NH₃ = 14.01 g/mol + 3.024 g/mol
Molecular mass of NH₃ = 17.03 g/mol
Ammonia consist of hydrogen and nitrogen both are nonmetals that's why ammonia is an covalent compound.
The net ionic equation of the reaction is:
- Pb²⁺ (aq) +2 I⁻ (aq) → PbI2(s)
<h3>What are net ionic equations?</h3>
Net ionic equations are equations where ions which remain in solution known as spectator ions are not shown in the equation. Only ions involved in formation of product are shown.
In the given equation, sodium and nitrate ions are spectator ions.
The net ionic equation of the given reaction is as follows:
- Pb²⁺ (aq) +2 I⁻ (aq) → PbI2(s)
In conclusion, spectator ions are not shown in net ionic equation.
