The most appropriate answer is A !!
As solvent temp is increased the solubility of solute increases !!
Answer:
Ocean
Explanation:
The maximum salinity is about 35 parts per mille. Among other terms, around 3.5 per cent of seawater weight is produced from salts dissolved.
So a lot of salt water in oceans

Answer:
The reducing agent is Hg (mercury) and the oxidixing agent is Cl (chlorine)
Explanation:
first find the oxidation charges of each of the different ions. All elements that are alone have a charge of 0. As you compare the reactants and products we can see that the chargers of Hg and Cl have changed.
Hg went from a charge of 0 to a charge of +1
Cl went from a charge of 0 to a charge of -1
remember when a substance gains electrons it is reducing and when a substance is losing electrons it is oxidizing.
use the acryonm

Answer:
132.94 kilo joules
Explanation:
We are given;
- Mass of benzene solution is 850 g
- Temperature change from 95°C to 3° C = 92° C or 92 K
We are required to determine the energy released by the cooling of benzene.
Taking the specific heat capacity of liquid benzene as 1.7 kJ/kg/K
Then we can determine the amount of heat energy released by using the formula;
Heat = Mass × specific heat × change in temperature
= 0.85 kg × 1.7 kJ/kg/K × 92 K
= 132.94 kilo joules
Therefore, the heat released by cooling benzene is 132.94 kilo joules
