)write the balanced equation for the reaction that occurs when methanol, ch3oh (l), is burned in air. what is the coefficient of oxygen in the balanced equation

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,

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.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
