Answer:
Forces inside the atom
The atom is comprised of three major particles—protons, neutrons and electrons. There are four forces (Electromagnetic, Strong, Weak, and Gravity) that are responsible for the behavior of the particles and thus keep the atom together.
Scientific knowledge is constantly being refined and changed as scientists perform studies using the scientific method. New discoveries such as the recent discovoery of water on Mars, cause scientists to re-evaluate their previously held theories.
I think the awnser to your question is C
The formula for beryllium chlorite is Be(ClO2)2.
The beryllium cation has a charge of 2+ and a chlorite ion has a charge of 1-. Using the crisscross method, we move the charge of the beryllium cation to the subscript position of the chlorite ion and the charge of the chlorite ion to the subscript position of the beryllium cation. So, we get Be1(ClO2)2. The ratio one-to-two cannot be reduced further. Since the subscript of Be is 1, we drop it and get Be(ClO2)2.
Answer:
A
Explanation:
The formula used is
PV = P1 * V1
P = x
P1 = 4x
V1 = 1
V2 = ?
x * 1 = 4x * V2 Divide both sides by x
x/x = 4x /x * V2
1 = 4*V2 Divide by 4
1/4 = 4*V2/4
1/4 = V2
The answer is A
