Theory- <span>a supposition or a system of ideas intended to explain something, especially one based on general principles independent of the thing to be explained.
Scientific law- </span>a statement based on repeated experimental observations that describes some aspect of the universe.
Answer:
The molarity of the formed CaBr2 solution is 0.48 M
Explanation:
Step 1: Data given
Number of moles CaBr2 = 0.72 moles
Volume of water = 1.50 L
Step 2: Calculate the molarity of the solution
Molarity of CaBr2 solution = moles CaBr2 / volume water
Molarity of CaBr2 solution = 0.72 moles / 1.50 L
Molarity of CaBr2 solution = 0.48 mol / = 0.48 M
The molarity of the formed CaBr2 solution is 0.48 M
Answer: Gas pressure is employed in a variety of industrial operations, and it was the catalyst for the industrial revolution. Many industrial machines were powered by steam in the early twentieth century. To heat the water molecules inside massive boilers, wood was burned.
Answer:
Kj/mol
Its an endothermic reaction
Explanation:
Enthalpy can be evaluated by using following formula -
where
q is the enthalpy or change in internal energy
m is the mass in kg
c is the specific heat
and 
is the change in temperature
Mass of HCl is equal to 
g/mol
or
Mass of HCl is equal to 
Kg/mol
Substituting the given values in above equation, we get-
Kj/mol
Enthalpy is positive thus it is an endothermic reaction
