Answer:
A
Explanation:
a heterogeneous mixture is one that is not uniform in composition.It is made up of non-uniform mix of smaller constituent parts that could be separated from one another using various means.
Specific heat capacity is the energy needed to raise the temrature of a substance of mass of 1kg by 1kelvin Q= Mc (delta) T delta T = change in temprature M = mass c= specific heat capacity q = energy if you take everything except C to be one Q will get bigger as C gets bigger

Explanation:
Answer:
This question appears incomplete
Explanation:
However, it should be noted that addition of soluble salts generally lowers the freezing point of water hence after the addition, water will no longer freeze at 0°C but lower.
Soluble salts tend to form more ions in water, it is these ions that are responsible for interfering with the hydrogen bonds hence lowering the freezing. Thus, (since each bag are of the same weight) <u>the bag that contains the salt that ionizes more in water will lower the freezing point by the greatest amount</u>.
NOTE: Different weight of the salts could lead to more ions been formed in the water by some salts as against the other.
