Antioxidants are the substance that prevent oxidation process in a cell, oxidation produce free radical, and free radicals harm the cell. The oxidation number is the count of electrons present in an atom.
<h3>What is ascorbic acid?</h3>
Ascorbic acid (vitamin C) is a water-soluble vitamin that is present in the citrus fruits and vegetables.
Ascorbic acid act as an antioxidant and prevent the production of free radicals in a cell.
Thus, Antioxidants are the substance that prevent oxidation process in a cell, oxidation produce free radical, and free radicals harm the cell. The oxidation number is the count of electrons present in an atom.

Answer:
Carbon monoxide + hydrogen ------> methanol
Explanation:
In writing a chemical equation, the substances which react together to form other substances are known as products and are usually placed on the left side of a the equation, whereas the substances that are formed by the reactants are known as products and are usually written on the right side of the equation. A forward pointing arrow is usually placed between the reactants and and products to show how the reaction proceeds from reactants to formation of products.
From the given equation, methanol is the product formed from the reactants carbon monoxide and hydrogen. Therefore, the equation will be:
carbon monoxide + hydrogen -----> methanol
First let us compute for the number of moles of butane
(molar mass = 58.12 g/mol)
number of moles = 145 g / (58.12 g/mol) = 2.49 mol
<span>We use the ideal
gas equation to calculate the volume:</span>
<span> V = n R T / P</span>
V = 2.49 mol * 62.36367 L torr / mol K * 308.15 K / 745
torr
<span>V = 64.35 L</span>
It’s C because is covalent
