The answer is 3. As 5 * 3 = 15.
Is there any other equations I may be able to help you with? :)

Answer:
robbery
Explanation:
The elements of robbery are 1) the felonious taking of personal property, 2) from the person or immediate presence of another, 3) against the will of the victim, and 4) accomplished by means of force or by putting the victim in fear.
Action of taking property by unlawfully from a person or place by force or threat of force is called robbery and all above condition satisfies the term robbery hence robbery is correct match.
Some physical properties change, but the substance keeps its identity.
When dealing with these kind of questions, understand that the keyword here is physical change. Thus, all options that says no physical properties change are WRONG. So this leaves us with only 2 answers left. However, this is a physical change, no chemical change. Thus, the substance will keep its identity and not change.
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
