Answer:
1 ethanol is right answer
Explanation:
CH3- CH2-OH
Answer:
O₈¹⁷
Explanation:
An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.
All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other.
In given statement there are 8 electrons it means the atomic number of given atom is 8 so it would oxygen. The atomic mass of oxygen is 16 while in given statement mass is 17 it means it is the isotope of oxygen that have one more neutron than oxygen 16.
Isotope of an element have same atomic number but different atomic mass due to different number of neutrons.
<span>Density is a value for
mass, such as kg, divided by a value for volume, such as m^3. Density is a
physical property of a substance that represents the mass of that substance per
unit volume. We calculate as follows:
Density = (130.278 - 20.550) / (142.419 - 130.278)/0.7918 = 7.16 g/mL</span>
I would think the answer would be C. Based off of what I've learned and heard. Sorry if it's not the correct answer though.
