i really dont know i just need points bad sorry bud
Answer:
It is made up of two elements.
Explanation:
To answer the question given above,
We shall determine the number of elements present in CaCl₂. This can be obtained as follow:
CaCl₂ contains calcium (Ca) and chlorine gas (Cl₂).
This implies that CaCl₂ contains two different elements.
Now, considering the options given in the question above, CaCl₂ is made up of two elements.
Well , first you write the formulas of the reactants and the reaction products. and then you balance the equation, making sure the number of atoms of each substance that appear among the reactants is the same that is in the reaction products.

Answer: 0.040 mol/l
Explanation: Molarity c = n/V (Concentration)
c = 0.060 mol / 1,5 l = 0,040 mol/l
