its not B because it donates and releases OH- ions
hope this helps
Sorry I skate and usually the smaller wheel rolls faster. Try C. then It's like longboard wheels they roll pretty fast.
Answer: Keq= [CO2]^6[H2O]^6/ [O2]^6
Explanation:
Answer:
I think it would be at 0.7 kg mass of the sun
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
