Answer:
water dissolves carbon dioxide
Explanation
carbon dioxide is soluble in water therefore when water is present it is unstable because it will keep dissolving.
Just for more clarification, lowercase k is the rate constant. Uppercase K is the equilibrium constant. You can actually use k to find K (equilibrium constant). K=k/k' This means that the equilibrium constant is the rate constant of the forward reaction divided by the rate constant of the reverse reaction
Answer:
The standard potential, E cell, for this galvanic cell is 0.5670V
Explanation:
Ni²⁺(aq) + 2e⁻ → Ni(s) E red = - 0.23V ANODE
Cu²⁺(aq) + 2e- → Cu(s) E red = + 0.337V CATHODE
ΔE° = E cathode - E anode
ΔE° = 0.337V - (0.23V) = 0.5670 V
Answer:
e. H₂O
Explanation:
The specific heat capacity is defined as the amount of heat required to raise the temperature of the substance in 1 unit. If you have to warm your room, you have to choose the substance with the <u>highest</u> specific heat capacity value. This substance will retain the highest amount of heat. From the options, the highest value is 4.184 J/g°C (water, H₂O). Thus, 1 gram of water will retain 4.184 J when the temperature is raised to 1°C. That is a higher amount of heat in comparison with, for example, granite, which is able to retain 0.79 J per gram when the temperature is raised to 1°C.
However, you have to consider that the boiling point of water is 100°C, so the temperature at which you have to warm the room is the temperature at which water will be passing to the gas state.
