Answer:
exothermic entropy is increased
Explanation:
An exothermic process is one whose rate increases when the temperature is decreased. Hence if a decrease in temperature favours the dissolution of more solute at equilibrium, then the process is exothermic.
Similarly, the dissolution of a solute in a solvent increases the disorderliness (entropy) of the system because of the increase in the number of particles present. Hence once a solute in dissolved, the entropy of the system increases.
Answer:
They are oxoanions of chromium in the 6+ oxidation state and are moderately strong oxidizing agents. In an aqueous solution, chromate and dichromate ions can be interconvertible.
Chemical formula: CrO2−; 4 and Cr; 2O2−; 7
Conjugate acid: Chromic acid
Molar mass: 115.994 g mol−1 and 215.988 g mol−1
Answer:
If a one kilogram block of lead absorbs 2,000 J of energy then the temperature rise will be larger. If 1,000 J of heat is absorbed by a 2 kg block of lead then the temperature of the block doesn't rise as much since the energy is shared between more particles.
