Answer:
See the answer below
Explanation:
Ethane will burn in oxygen to form carbon dioxide and water according to the following balanced equation:

<em>From the equation, it means that for every one mole of ethane, three and a half moles of oxygen gas are required for complete combustion into carbon dioxide and water. Two and three moles of carbon dioxide and water would be produced respectively for every one mole of ethane that burns in three and a half moles of oxygen gas. </em>
The R-COOH. Unbranched hydrocarbon chain with carboxyl at one end.
The number indicates the number of atoms of each element in a molecule of a substance is the script number to the right of the element indicates the number of atoms. Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.
The four systems that describe the functions of the circulatory systems are:
- oxygen is delivered to cells throughout the body by this system
- This system removes carbon dioxide from organs & delivers it to the lungs.
- Carbon dioxide exits the body through this systems
- This system's organs pass oxygen into the bloodstream.

Answer:
False
Explanation:
The papillary muscles of both right and left ventricles began to contract shortly before the other ventricular muscles (systole) so that they can take up the slack on the chordae tendineae as the full force of ventricular contractions sends blood against the atrioventricular (AV) valve flaps.
They prevent the backward flow of blood to atria from ventricles. So if they contract after the ventricle systole they would not be able to perform their job.
