Liono4ka [1.6K]

Answer:

law of multiple proportions

Explanation:

The law of multiple proportions states that, if two elements A and B, combine to form more than one chemical compound. Then the various masses of one element A, which combine separately with a fixed mass of element B are in  simple multiple ratio.

We can see that the ratio of oxygen that combines with carbon in the two compounds( A and B) is 1:2. This demonstrates the law of multiple proportions.

The substances A and B must be CO and CO2 respectively.

Describe the number of protons, neutrons, and electrons in the atom, where each type of particle is located, and how the terms a
Igoryamba
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).

Protons and neutrons are in the center of the atom, making up the nucleus. Electrons surround the nucleus. Protons have a positive charge.

Each element has a specific mass number and a specific atomic number. These two numbers are fixed for an element. The mass number tells us the number (the sum of nucleons) of protons and neutrons in the nucleus of an atom. it has mass number 235 , it means that the sum of neutrons and protons in a carbon atom is 235.3

<h2>ANSWER:</h2>

Yes, in this group both events "Oddems Family" and "Thirteenth Night" are mutually exclusive.

<h3>Explanation:</h3>

Mutually exclusive is an statistical term which means the probability of occurrence of two separate event at the same time is zero. It means two events can not be occurred simultaneously.

For example, if we roll the deck ant the probability of coming 1 and 6 at the same time is zero and both events do not depends upon each others occurrence.

Hence only one drama can run in theater at one time. So they are mutually exclusive events.
