Answer:
D
Explanation: Decreasing the temperature of the system would lower the reaction rate.
Neither of them are used in magnets they don’t attract metal
Answer:
None of the options are correct.
Explanation:
1) when the temperature of the solution is increased the solubility of the gas in the liquid decreases , hence option 1 is incorrect.
2)The heat released by the dissolution of an ionic compound in water is heat of hydration of the compound and is independent of the initial temperature of the solution.
3) The solubility of a liquid in water is not affected significantly by the pressure changes in the system as gases only have a significant cahne in solubility with change in pressure.
The reactants are all the formulas to the left of the arrow, which are:
hcI(aq) nahco3(aq)
