Calcium Chloride's chemical formula is CaCl2.
Answer: The students should take 49.67 g acid acetic in benzene solution. With significant digits 4.967X10 g.
Explanation: If 220 g solution 30.2% w/w acetic acid has 66.44 g acid acetic (220 g solution * 30.2%), 49.67 g solution 30.2% acetic acid has 15 g acetic acid (with a simple three rule, 15 g acetic acid*220 g solution/66.44 g acetic acid)
Answer:
Option B. The equilibrium of the reaction would shift to the right.
Explanation:
According to Le Chatelier's principle, when an external constrain such as change in concentration, temperature or pressure is imposed on a chemical system in equilibrium, the equilibrium position will shift in order to neutralize the effect.
Now, let us answer the question above.
From the question given above, the equation is:
A + B <===> C + D
Increasing the concentration of A will shift the equilibrium position to the right.
This is true because increasing the concentration of A means having more reactants in the system. So the reactants react to produce more product thereby shifting the equilibrium position to the right.
<span>The solubility of a gas decreases with increasing temperature. This is the opposite of water whose solubility increases with increasing temperature. Gases are generally more soluble in colder temperatures. For example, oxygen is more soluble in hot water than cold water. This is why hot water can kill fish due to low oxygen.</span>
