When’s I would like to say that it may be B because
Answer:
Ammonia acts as an Arrhenius base because it increases the concentration of OH⁻ in aqueous solution.
Explanation:
The acid-base theory of Arrhenius explains that in aqueous solutions both acid and base dissociate, releasing ions in the solution. The acid release the ion H⁺ and some anion, and the base release the ion OH⁻ and some cation.
In water, the reaction of ammonia is:
NH₃ + H₂O ⇄ NH₄⁺ + OH⁻
Because of that, ammonia is an Arrhenius base.
Answer:
It's true.
Explanation:
In sub-energy level : number of orbitals
One is b, through the logic that group one can only lose or gain one electron and group 18 which is the noble gases and 132 doesn't make sense.
number two is ionic because they are metals who usually form bonds with non metals, covalent bonds are nonmetals and nonmetal bonding.
for three if the charge is a positive then yes because the atom then becomes neutral. True.
B
B
A
Use this equation:
q = mc∆T
q is the heat energy your trying to find out
m is the mass of water (150g)
c is the specific heat capacity of water (4.18)
∆T is the temperature change (96.3-38.8)
so just multiply m c and ∆T to find q in joules
