Answer:
magnesium+ hydrochloric acid is the reactants
Explanation:
the reactants are always in the left and the products are always in the right by
magnesium+hydrochloric acid ⇒ magnesium chloride + hydrogen
by combining magnesium and hydrochloric acid it produces magnesium chloride and hydrogen.
hope this helps..
Answer:
23 g of Zn will produce 0.352 mole of zinc chloride.
Explanation:
Given data:
mass of Zn = 23 g
Moles of ZnCl = ?
Solution:
Chemical equation:
2Zn + CuCl₂ → 2ZnCl + Cu
Number of moles of Zn:
<em>Number of moles of Zn = mass/ molar mass</em>
Number of moles of Zn = 23 g / 65.38 g/mol
Number of moles of Zn = 0.352 mol
now we will compare the moles of ZnCl with Zn because it is limiting reactant.
Zn : ZnCl
2 : 2
0.352 : 0.352
So 23 g of Zn will produce 0.352 mole of zinc chloride.
Answer: oh i thought i knew it nvm im sorry love
Explanation:
Because the decomposition is the reverse process of the formation.
Enthalpy is a function of state, which means that the value dependes only on the state and not the pathway.
Then the change of enthalpy is the same in magnitude for both cases but in formation the change is netavie (releases energy) and in the other is postive (absorbs energy).
