Consider the balanced equation below. 8H2 + S8 Right arrow. 8H2S Based on the mole ratios, what can most likely be predicted? 1
Arte-miy333 [17]

Answer:

8 mol of hydrogen will react with 1 mol of sulfur.

Explanation:

We'll begin by writing the balanced equation for the reaction.

This is given below:

8H2 + S8 —> 8H2S

Now, let us carefully observe the mole ratio of the reactants.

This is illustrated:

The mole ratio of the reactants ( i.e H2 and S8) is 8 : 1

From the balanced equation above,

We can thus, concluded that:

8 moles of H2 will reacted with 1 mole of S8.

Refer to the reaction between magnesium and oxygen In the introduction. What elements is oxidizing?write the oxidation number fo
erica [24]

Answer:

Oxidizing element: Mg

Explanation:

Reaction of magnesium and oxygen can be written as:

2Mg +O_2 \rightarrow 2MgO

while writting chemical reaction between two atom or element then write their natural form i.e. how that atom or element exist in the nature.

eg. reaction of any element with Oxygen atom then we can not write directly O because oxygen exist in the nature in form of O_2

finding oxidation number each side:

Reactant side:

Mg=0;

O=0;

product side:

Mg=+2;

O=-2;

from above:

oxidation number of Mg is increasing hence this is oxidizing element
