_Cuo +H, → _Cu + _H,0

Chemistry
1 answer:
Elena-2011 [213]3 years ago
3 0
<h3>Answer:</h3>

CuO(s) + H₂(g) →  Cu(s) + H₂O(l)

<h3>Explanation:</h3>
  • Assuming the reaction is the reduction of CuO by H₂
  • Then the balanced equation for the reaction is;

CuO(s) + H₂(g) →  Cu(s) + H₂O(l)

  • The equation shows the reducing property of hydrogen gas, such that hydrogen reduces metal oxides such as copper(ii)oxide to the respective metals.
  • The law of conservation requires chemical equations to be balanced so as the mass of reactants will be equal to that of products.
  • In this case; there is 1 copper atom, 1 oxygen atom and 2 hydrogen atoms on both side of the equation and thus the equation is balanced.

The following reaction is an example of what type of equilibrium reaction?
Mrac [35]

Hello, Brainly User!

A heterogeneous equilibrium reaction is when there are different phases in the reaction. An equilibrium reaction is a reaction that can go in both the forward and reverse directions, and the concentrations of the reactants and products remain the same.

So therefore, your answer is A. Heterogeneous!

Hope i helped and i was honored to answer your question!

Have a great day..

Mention any two factors that determines Cis/Trans Isomerization​
kenny6666 [7]

Answer:

1. There most not be rotation within the molecule.

2. Two non identical group must be present in the double bonded carbon atom.

Explanation:

This is because cis/ trans isomerism are that exhibit different structural configurations where the atoms are spartially arranged. They are also refered to as geometric isomers. They cannot be interconverted at room temperature because it requires the bonds to be broken and restructured.

Cis shows that the functional groups on present in the same side which trans isomerism show that the functional groups are on opposite sides.
