Answer:
0.0125mol
Explanation:
Molarity (M) = number of moles (n) ÷ volume (V)
n = Molarity × Volume
According to this question, a 0.05M solution contains 250 mL of NaOH. The volume in litres is as follows:
1000mL = 1L
250mL = 250/1000
= 0.250L
n = 0.05 × 0.250
n = 0.0125
The number of moles of NaOH is 0.0125mol.
Explanation:
The reaction rate decreases with a decrease in temperature. Catalysts can lower the activation energy and increase the reaction rate without being consumed in the reaction. Differences in the inherent structures of reactants can lead to differences in reaction rates.
when the waves pass from the deeper water to the shallower water its speed will decrease.
<h3>
What is refraction of wave?</h3>
Refraction of wave is the change in direction of a wave passing from one medium to another caused by its change in speed.
For example, waves travel faster in deep water than in shallower water.
Thus, we can conclude that when the waves pass from the deeper water to the shallower water its speed will decrease.
