How many moles of O2 molecules should be supplied to burn 1 mol of CH4 molecules in a domestic furnace?

1 answer:

4 0

The combustion of 1 mole of methane (CH4) in a domestic furnace requires 2 moles of O2 molecules, assuming the combustion was complete or ideal. To solve this problem, use stoichiometry of the reaction's balanced chemical equation:

CH4 + 2O2 --> CO2 + 2H2O

The ratio of CH4 to O2 in terms of moles is 1:2. So 1 mole of CH4 needs 2 moles of O2.

vfiekz [6]

Answer:

C. Its oxidation number increases.

Explanation:

Oxidation is defined as the loss of electrons by an atom while reduction is the gain of electrons by an atom.
Atoms of elements have an oxidation number of Zero in their elemental state.
When an atom looses electrons it undergoes oxidation and its oxidation number increases.
For example, an atom of sodium (Na) at its elemental state has an oxidation number of 0. When the sodium atom looses an electrons it becomes a cation, Na+, with an oxidation number of +1 , the loss of electron shows an increase in oxidation number from 0 to +1.

The table shows the number of reactants and products present during two separate chemical reactions.

aleksandr82 [10.1K]

Answer: Option (a) is the correct answer.

Explanation:

A decomposition reaction is defined as a reaction where a compound dissociates into two or more atoms.

For example, $A \rightarrow B + C + D$

Whereas a chemical reaction in which two reactants combine together to result in the formation of a compound is known as a synthesis reaction.

For example, $A + B \rightarrow C$ is a synthesis reaction.

Thus, we can conclude that the statement chemical reaction A, because the reactant is a compound identifies the decomposition reaction and describes a substance is involved.

(ii) When shale gas is burned, the hydrogen sulfide reacts with oxygen.

Elenna [48]

Answer:

See explanation

Explanation:

Now , we have the equation of the reaction as;

2H2S(g) + 302(g)------->2SO2(g) + 2H2O(g)

This equation shows that SO2 gas is produced in the process. Let us recall that this same SO2 gas is the anhydride of H2SO4. This means that it can dissolve in water to form H2SO4

So, when SO2 dissolve in rain droplets, then H2SO4 is formed thereby lowering the pH of rain water. This is acid rain.
