Mass is the quantity of matter present in a substance. The masses of the most abundant molecule of are 85.9325, 87.9296, and 89.9267 amu.
What are isotopes?
Isotopes are the elements of the same species with the same atomic number but differ in atomic mass and physical properties.
% abundance and mass of chlorine are:
Cl-35 = 34.9688 amu
Cl-37 = 36.9659 amu
% abundance and mass of oxygen are:
O-16 = 15.9949 amu
O-17 = 16.9991 amu
O-18 = 17.9991 amu
O -16 is the most abundant form of the oxygen isotope and Cl -35 of chlorine.
The masses of the most abundant molecule are given as:
Cl-35, Cl-35, O-16:
Cl-35, Cl-37, O-16:
Cl-37, Cl-37, O-16:
Therefore, 85.9325, 87.9296, and 89.9267 amu are the masses of the most abundant form of the molecule.

Chlorine has the following % abundance and mass:
Cl-35 = 75.76 %, 34.9688 amu
Cl-37 = 24.24 %, 36.9659 amu
Oxygen has the following % abundance and mass:
O-16 = 99.757 %, 15.9949 amu
O-17 = 0.038 %, 16.9991 amu
O-18 = 0.205 %, 17.9991 amu
Based in the % abundance O-16 is the most abundant oxygen isotope and Cl-35 is the most abundant chlorine isotope
So the most abundant molecule of Cl2O and their respective mass are as follows:
1) Cl-35, Cl-35, O-16
Mass = 34.9688 amu + 34.9688 amu + 15.9949 amu = 85.9325 amu
2) Cl-35, Cl-37, O-16
Mass = 34.9688 amu + 36.9659 amu + 15.9949 amu = 87.9296 amu
3) Cl-37, Cl-37, O-16
Mass = 36.9659 amu + 36.9659 amu + 15.9949 amu = 89.9267 amu

Plants need energy for Reproduction, Photosynthesis, Growth, and Development amongst others.
Required Energy in Plants
To produce their own food energy, which is referred to as "photosynthesis," plants need water and sunlight. They need energy because they are living things.
Photosynthesis is the process by which plants turn solar energy into sugar. Light energy is utilized by photosynthesis to transform carbon dioxide and water.
Numerous biological functions, such as growth and reproduction, require energy. Therefore, energy is absolutely essential.

B The oxygen in the air forms ozone in presence of UV rays
C Dust and soot particles being suspended in the air
D Sulphur dioxide being released in the air
Answers
the answer is B not A
let me explain why see a says water vapor in the air turns to liquid water in the form of rain see that is a physical change not a chemical change it is B because it is undergoing a chemical change by the uv rays for that reason it is not D because that is just releasing sulfur dioxide in the air that is not a chemical change nor a physical change so then i leaves us with C so C is wrong because it just being suspended in the air not physical or chemical change
can i also have brainlyest i never had it before
B) one Neutron
C) six Electrons
D) These masses are too tiny to measure
Answers
Answer:
C
Explanation:
Answer:
six electrons
Explanation:
Electrons have almost virtually no mass and much less than a proton and neutron.
(a neutron and electron have about 1 amu while electrons have 0.000548 amu)
B. As particles travel in straight lines, their paths sometimes meet, and then they bounce apart with no gain or loss of energy.
C. When particles pass close enough to one another, their attractions pull them together, and then they bounce apart with a loss of energy.
D. As particles travel in straight lines, their paths sometimes meet, and then they bounce apart with a loss of energy.
Answers
Answer: option B. As particles travel in straight lines, their paths sometimes meet, and then they bounce apart with no gain or loss of energy.
Explanation:
The kinetic-molecular theory explains the the properties and behavior of the gases in terms of the energy, size, and motion of the particles that form the gases.
According to this model, the gas particles are in constant random motion. The particles travel in straight line until they collide either with other particles or with the walls of the vessel. Such collisions are elastic, meaning that energy is not either gain or loss. Therefore, this theory does not consider either attractions or repulsions between the particles. The particles bounce apart and the total kinetic energy is conserved.
