Answer:

Explanation:
-Specific heat capacity is given by the formula:

Where:
is the heat gained or loosed by the substance
is the mass of the substance
is the specific heat of the substance
is the change in temperature
#We make c the subject of the formula and substitute to solve for it:

Hence, the specific heat capacity of the ice is 
Remember velocity = distance/time so that mean you would do 60/3 which equals 20 so the speed(velocity) equals 20
The information given in the question is not enough to determine the acidity of the solution. This is because, acidity can only be found with the equation: pH = -log [H+].
In order to determine the acidity of the solution, the half titration point value is needed, this will make it possible to determine the value of H30+. If the half point titration value is known, then Ka will be equivalent to pH and the value will be evaluated using the equation: - log (1.6 * 10^-10).
Answer:
Decreased because the method can not distinguish oxygen from the gas added
