Chemistry
1 answer:
borishaifa [10]3 years ago
6 0

<u>Answer:</u> The student must add 2 infront of both H_2O and SO_2 to make the equation balanced.

<u>Explanation:</u>

A balanced chemical equation is one where all the individual atoms are equal on both sides of the reaction. It follows the law of conservation of mass.

For the given unbalanced chemical equation:

2H_2S+3O_2\rightarrow H_2O+SO_2

<u>On the reactant side:</u>

Atoms of H = 4

Atoms of S = 2

Atoms of O = 6

<u>On the product side:</u>

Atoms of H = 2

Atoms of S = 1

Atoms of O = 3

To balance the equation, a student must balance the atoms by adding 2 infront of both H_2O and SO_2

For the balanced chemical equation:

2H_2S+3O_2\rightarrow 2H_2O+2SO_2

Explain the similarities and differences between putting a beaker of ethanoic acid in the refrigerator and mixing it with sodium
frez [133]

Answer:

See explanation

Explanation:

When a beaker of ethanoic acid is placed in the refrigerator, its temperature drops and the vessel feels cool.

Now, when we mix ethanoic acid and sodium carbonate, an endothermic reaction occurs, fizzing is observed as carbon dioxide is given off and heat is lost to the surroundings causing the reaction vessel to feel cool to touch.

The difference between putting ethanoic acid in the refrigerator and adding  sodium carbonate to the solution is that, in the former, no new substance is formed. The substance remains ethanoic acid when retrieved from the refrigerator. In the later case, new substances are formed. The substance is no more ethanoic acid because a chemical reaction has taken place.
