Answer:
Clouds are formed when water warms up and changes into a gas called water vapor, which rises up into the air.
Explanation:
The Ksp of cobalt(II) hydroxide is equal to [OH-]2[Co2+]=5.92*10-15. And [OH-]=2[Co2+]=2*[Co(OH)2](dissolved). So the molar solubility of this compound is 1.14*10-5 M.
Answer:
Energy of the Reactant: increases
Energy of the product: not at all
Rate of reaction: increases
Enthalpy: not at all
Activation energy: decreases
Explanation:
Catalyst is a substance that increases the rate of reaction than normal to form a product.
Catalyst affect differently to different factors of reaction. A catalyst is meant to increase rate of reaction by lowering the activation energy, so that collision between reactant increase and that passes the energy barrier to form the product faster.
Catalyst has no effect on Enthalpy as change in enthalpy only depends on the chemical compositions of the reactants and products.
Catalyst also increases energy of reactant so that they can collide faster than before and do not affect the energy of product at all.
Hence, the correct answer is:
Energy of the Reactant: increases
Energy of the product: not at all
Rate of reaction: increases
Enthalpy: not at all
Activation energy: decreases
