The answer is c because of going left to right
The main atomic partilces are electrons, protons and neutrons.
Electrons are around the nuclei and have negative charge.
Protons and neutrons are in the nulei of the atoms. Protons are positive and their charge balance the charge of the electrons, so the atom is neutral.
Neutrons have no charge.
So, the answer is:
the charge of electrons is negative, the charge of the protons is positive and the neutrons have no charge.
The scale used to measure the basicity of a substance is called the pH Scale. A base which when measured on a pH scale obtains a value greater than 7 but less than or equal to 10 is weak base and from 10-14 is strong base
<h3>Meaning of Base and basicity</h3>
A base is any substance that has the ability to accept hydrogen ion in water and also netralize an acid when mixed together.
Basicity is an attribute associated with the pH scale measurement of values above 7 to 14.
Basicity increases on the scale from 7 to 14. On the pH scale 7 is neutral. So the higher we go the more basic a solution becomes until it gets to its highest point which is 14.
In conclusion, The scale used to measure the basicity of a substance is called the pH Scale. A base which when measured on a pH scale obtains a value greater than 7 but less than or equal to 10 is weak base and from 10-14 is strong base

Answer:
2,500,000 litres or 2.5 megalitres of water.
Olympic size pools measure: 50 metres long, 25 metres wide, and a minimum of 2
metres deep.
(25m x 50m x 2m = 2,500m3; 1L = 0.001m3 so 2,500 x 1000 = 2,500,000L)
660,430 gallons of water.
50 meters = 164.041995 feet (a)
25 meters = 82.0209975 feet (b)
2 meters = 6.5616798 feet (c)
Volume = (a) * (b) * (c) = 88,286.66721 cubic feet Explanation:
