Answer : The coefficient used for the oxygen in balanced chemical reaction is, 3.

Explanation :

Balanced chemical reaction : It is defined as the number of atoms of individual elements present on reactant side must be equal to the product side.

When methanol is burned in air then it react to give carbon dioxide and water as a products.

The balanced chemical reaction will be,

2CH_3OH(l)+3O_2(g)\rightarrow 2CO_2(s)+4H_2O(g)

This reaction is a combustion reaction in which a hydrocarbon react with oxygen to given carbon dioxide and water as a products.

By stoichiometry we can say that, 2 mole of methanol react with 3 moles of oxygen to give 2 moles of carbon dioxide and 4 moles of water.

Hence, from the balanced chemical reaction we conclude that the coefficient used for the oxygen is 3.

In a neutral atom, the number of protons is always equal to what other part of the atom?
Licemer1 [7]

Answer:

b. The number of electrons

Explanation:

A "neutral atom" has a <u>neutral charge</u>. This means that <em>its charge is equal to </em><em>zero. </em>In order for the charges to cancel out each other, the atom's <em>positive charge should be equal to the negative charge. </em>These being said, the number of electrons<em> (negatively-charged)</em> is then equal to the number of protons <em>(positively-charged). </em>Those atoms which are not neutral are called <em>"ions."</em> This means that they either have more or less electrons than the protons.

Bogdan [553]

Answer:

Functional groups.

Explanation:

Functional groups are the specific substituents present within the molecules which are responsible for characteristic chemical properties the molecule shows.

Glucose contains alcohol and aldehyde group while hexanoic acid contains carboxylic acid group. <u>The presence different types of the functional groups in both the compounds results in the difference in the properties of both the compounds.</u>
