Answer:
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).

Answer:
The correct answer is "two".
Explanation:
The main bondings that has an effect in a Lewis structure in NO2Cl are the double bondings occurring between the Oxygen atoms and the Nitrogen atom. Since the NO2Cl compound has two oxygen atoms attached to the nitrogen atom, two equivalent lewis structures will be necessary to describe it. I attached an example of two equivalent Lewis structure corresponding to a NO2 molecule.
Answer:
<h2>The answer is 100 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
<h3>Force = mass × acceleration</h3>
From the question
mass = 10 kg
acceleration = 10 m/s²
We have
Force = 10 × 10
We have the final answer as
<h3>100 N</h3>
Hope this helps you
Answer: increase pressure and decrease temperature.
Explanation:
Increasing pressure uses force to make the gas molecules come closer together. (Decreasing pressure allows the molecules to spread out) Decreasing temperature will also cause the molecules of gas to come together closer. (Heat excites molecules causing them to spread out and therefore expand)
