Answer:Hydrogen gas is prepared in laboratory by the action of dilute HCl upon granulated zinc. Note: This is a redox reaction since Zn is oxidized and H+ ions is reduced here. Procedure: ... Some crystals of copper sulphate are added to increase the rate of reaction.
Explanation:
Answer : The concentration of ion is, 0.00371 M
Explanation :
First we have to calculate the concentration of ion.
The solubility equilibrium reaction of will be:
The expression for solubility constant for this reaction will be,
Now we have to calculate the concentration of ion.
The solubility equilibrium reaction of will be:
The expression for solubility constant for this reaction will be,
Thus, the concentration of ion is, 0.00371 M
Answer:
The particles moves faster thus Expanding the liquid
The price would not be a physical property
Answer:
It causes light to slow down significantly
Explanation:
The index of refraction of a substance describes the speed of light in that substance, as a ratio of the speed of light in vacuum to its speed in that substance.
