Answer:
The answer to your question is A. Decomposition
Explanation:
In the picture, we can observe that there is only one reactant that after the reaction are formed two products.
We observe that this is a decomposition reaction.
It is not a synthesis reaction, this reaction is the opposite of a decomposition reaction.
In a single-replacement and double-replacement reaction, there is an interchange of cations between the reactants, this does not happen in the picture.
The element that has the least is na
Answer is: mass od zinc is 392,28 g.
N(Zn) = 3,6·10²⁴.
n(Zn) = N(Zn) ÷ Na.
n(Zn) = 3,6·10²⁴ ÷ 6·10²³ 1/mol.
n(Zn) = 6 mol.
m(Zn) = n(Zn) · M(Zn).
m(Zn) = 6 mol · 65,38 g/mol.
m(Zn) = 392,28 g.
Na - Avogadro number.
n - amount of substance.
M - molar mass.
Answer: Nuclei combine to form a heavier nucleus, releasing energy.
Explanation: e.g two deuterium nucleus (Hydrogen-2 isotopes) forms an He nucleus and energy is released.
