When a reactant is removed based on a reaction at equilibrium, the condition favors the backward reaction. This obeys the Le Chatelier's principle which states that any disturbance in the system shall be dealt in a way that the system counters that disturbance.
Answer: 0.03798 kilograms
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 
of particles.
To calculate the moles, we use the equation:
1 mole of chlorine gas 
weighs = 71 g
Thus 0.535 moles of chlorine gas will weigh = 
(1kg=1000g)
Thus there are 0.03798 kilograms in 12 L of chlorine gas.
Answer:
<h2>2.6 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question we have
We have the final answer as
<h3>2.6 g/mL</h3>
Hope this helps you
Answer:
The Cl⁻ and K⁺ are spectator ions.
Explanation:
Balanced Chemical equation:
BaCl₂(aq) + K₂CrO₄(aq) → BaCrO₄(s) + 2KCl (aq)
Ionic equation:
Ba²⁺(aq) + 2Cl⁻(aq) + 2K⁺(aq) + CrO₄²⁻(aq) → BaCrO₄(s) + 2k⁺(aq) + 2Cl⁻ (aq)
Net ionic equation:
Ba²⁺(aq) + CrO₄²⁻(aq) → BaCrO₄(s)
The Cl⁻ and K⁺ are spectator ions that's why these are not written in net ionic equation. The BaCrO₄ can not be splitted into ions because it is present in solid form.
Spectator ions:
These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equation.
