The molecular mass for C2H4 should be: 2*12 + 4*1= 28 gram/mol. Then the amount of mol in 88.9 grams C2H4 should be: 88.9g/ (28g/mol)= 3.175 mol.
To answer this question, you need to know the reaction formula for the problem. The formula should be:
C2H4 + 3O2 --> 2CO2 + 2H2O
In the formula, every 1 C2H4 will be reacted with 3 O2. Then the amount of oxygen needed would be: 3/1 * 3.175 mol= 9.525 mol
Answer:
Electrons-negative
Protons-positive
Neutrons-neutral
Explanation:
Electrons have a negative charge, protons have a positive charge, and neutrons have no charge, so they have a neutral charge.
Phosphatase removes the phosphate groups from protein molecules during the dephosphorylation process. As a result, a phosphatase can deactivate a protein that has been activated by a kinase. Dephosphorylation, however, cannot be reversed.
<h2>What is Phosphorylation?</h2>
It is a process in which a molecule gets attached to a phosphoryl group.
The opposite of the phosphorylation is dephosphorylation in which the molecule looses a phosphoryl group.

Answer:
Auricle/pinna
Explanation:
The pinna is a flap of skin and cartilage which partially covers the opening to the external auditory meatus. It collects and concentrates sound waves into the auditory meatus. The pinna leads into the external auditory meatus which is a tube that directs sound waves to the eardrum also called the tympanic membrane.
Answer:
Mass is the measurement of matter an object contains while weight is the gravitational pull the earth has on an object.
Mass is important to measure because it will measure the amount of force it will take to move the object.
