Chapter 4, Problem 5RQ
Summary Introduction
Introduction: The process, in which one or more molecules react with each other to form new molecules, is known as a reaction. The rate of the reactions can be increased by the enzymes that act as biocatalyst and participate in reactions to lower down its activation energy.

SITUATION:You are a chemist in a manufacturing company which produces acetaldehyde, CH3CHO. This is prepared by the reaction of ethanol with copper (II) oxide according to the following equation: CH3CH2OH + CuO → CH3CHO + H2O + CuIf there are 1620 g of ethanol and 1020 g of CuO readily available in the laboratory, what mass of acetaldehyde can be produced?
QUESTIONS: 1. Would you recommend the company to buy more ethanol or copper (II) oxide? Why?2. How many grams of acetaldehyde will be produced from the readily available materials?3. How many grams of the excess reactant will be left after the reaction?4. If your actual yield is 552.6 g, what is its percent yield?
The 2-carbon alcohol called ethanol is most common because it's made from
something else very common: sugar! (this is also why ethanol is the one alcohol
that's not toxic, our bodies can metabolize it). Ethanol is mass-produced in
factories on an industrial scale, and is commonly used as a fuel (or mixed as an
additive into other fuels). The combustion reaction below shows that 6 molecules
of oxygen is required to completely burn two molecules of ethanol. How many
molecules of carbon dioxide are produced after burning ethanol?
ethanol + oxygen
carbon dioxide + water
20,H OH + 60,
+ 6H,0

- This reaction is exergonic because the reactants have more potential energy than the products.arrow_forwardendothermic reactions absorb energy from their surroundings. If chemicals for an endothermic reaction are added to water, the water's temperature drops (the water gets colder! Ever use a first aid "cold pack", where you squeeze a pouch to release chemicals inside and the pouch becomes ice cold? That's an endothermic reaction!) For endothermic reactions, when you use the equation Q = m x C x (delta T), the "Q" is a negative number because the water LOSES energy. The answer is negative because the water temperature drops, the CHANGE registered on the thermometer is negative. Type a negative number to answer this question: if your water starts at 19 degrees Celsius, and a couple of minutes after adding chemicals the water temperature becomes 15 degrees, the value of "delta T" is degrees Celsius. *arrow_forwardWhen you eat starchy foods resulting in a breakdown to give glucose to the body, you have induced a(n): Group of answer choices ion combustion oxidation-reduction reaction oxygen combustion Ion-reduction reactionarrow_forward
