You have three molecules of glucose (3C6H12O6). How many carbon atoms do you have?. . A. 3. . B. 6. . C. 18. . D. 36. 2. Which of the following is a homogenous mixture of two or more pure substances? . A. oxygen. B. water. C. air. D. alcohol.

One molecule of glucose has 6 carbon atoms. So if you have three molecules of glucose, simply multiply 3 by 6 carbon atoms. The correct answer is C. 18 Carbon atoms.

The correct answer for the second questions is C. Air. A homogenous mixture is a mixture in which its components are uniformly distributed throughout the mixture. It has a sigle phase.

Answer:

1. C. 18 atoms of carbon

2. C. Air

Explanation:

1. The formula of one molecule of glucose is

\(C_{6}H_{12}O_{6}\)

In this formula we have:

Carbon: 6 atoms

Hydrogen: 12 atoms

Oxygen: 6 atoms

if we have three glucose molecules, we have to multiply the formula (\(C_{6}H_{12}O_{6}\)) by three

\(3(C_{6}H_{12}O_{6})\\C_{18}H_{36}O_{18}\)

In this formula we have:

Carbon: 18 atoms

Hydrogen: 36 atoms

Oxygen: 18 atoms

2. A homogeneous mixture is the combination of 2 or more unidentifiable elements or substances within the solution.

Homogeneous mixtures are characterized by being uniform, this means that the elements that compose it are not distinguishable.

A. Oxygen is molecule \(O_{2}\)

B. Water is molecule compose by 2 elements \(H_{2}O\)

C. Air is a mixture of several gases.

D. Alcohol is compound of carbon, hydrogen and oxygen.\(C_{2}H{5}OH\)
