A particular Ci atom has a mass number of 37. Which statements about the atom are correct? Check all that apply.
It contains 37 protons.
It contains 20 neutrons.
It has an atomic number of 17.
It contains 37 neutrons.

It contains 20 neutrons

It has an atomic number of 17.

Explanation:

According to this question involving chlorine atom (Cl), the mass number (A) is said to be 37. The mass number of an element is calculated by adding the proton number and the neutron number i.e.

Mass no. = Proton no. + Neutron no.

The proton number is also called atomic number, and in this case as it is on the periodic table, the atomic number of Chlorine is 17. This means that chlorine atom has 17 protons. To calculate the number of neutrons in 37Cl, we say:

neutron no. = 37 - 17

neutron no = 20

From the above calculation, the following are true of 37 Cl:

- It contains 20 neutrons

- It has an atomic number of 17.

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen

explanation:

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
