Which of the following is the correct word equation for the reaction described below? Methanol (CH3OH) forms when carbon monoxide reacts with hydrogen.
carbon monoxide + methanol - hydrogen
methanol - carbon monoxide + hydrogen
carbon monoxide + hydrogen - methanol
methanol + hydrogen - carbon dioxide

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

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.
