Answer:
A. Calorimeter
Explanation:
A calorimeter is an apparatus that can be used to measure the quantity oh heat in a chemical reaction or the amount of heat that accompanies a physical change and also determine the specific heat capacity of a substance.
It is used extensively in physics, chemistry and the study of thermodynamics. In its simplest form, a calorimeter contains a thermometer which is attached to a container filled with water and suspended above a combustion chamber.
A mixture of calcium acetate and sodium phosphate would produce as a precipitate.
<h3>Precipitation reaction</h3>
Precipitates are insoluble salt formed from the reaction of two soluble salts.
The equation of the reaction between calcium acetate and sodium phosphate is represented by the equation below:
The produced in the reaction is an insoluble salt and, hence, a precipitate.

Answer:
Molarity = 0.5 M
Osmolarity = 0.5 x 2 = 1 Osmpl.
Molecules of Cl2 = 6.02 x / 4= 1.505 x no. of molecules
Explanation:
If we add half mole in 1L volume than molarity will obviously be 0.5 M.
The osmolarity is molarity multiplies by number of dissociates of solute that for CaCl2 are 2. So, 2 x 0.5 = 1
Half will be molecules of Ca and half will be of Cl2 for 0.5M.
Are there choices? Probably speeding, drunk driving, ice, or rain.
Speeding and drunk driving would be the top answers though if you don't have choices.
