The fact that you want to yes is funny
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: Mass number

It all starts from Carbondioxide. This Carbondioxide is dissolved in the blood and taken by red blood cell and converted into carbonic acid. It then dissociates to form a bicarbonate ion 
and a hydrogen ion 
This <--> means that the whole process is reversible. It is a buffer system to maintain the pH in the blood and duodenum. And also to support proper metabolic function.
I think the correct answer from the choices listed above is the second option. A way that the elements are grouped on the periodic table would be that elements with similar bonding properties are in the same column. <span>Each column is called a </span>group<span>. The elements in each </span>group<span> have the same number of electrons in the outer orbital.</span>
