If the prefix mega is added to the unit of the quantity being described, the magnitude of quantity increases by 10^{6} times i.e. 1 million times.
For Example- 1 MW = 1000000 watts
Explanation:
Al(OH)4-(aq) plus 4H plus (aq) and Al3 plus (aq) plus 4H20(I)
<u>Answer:</u> The atom with 6 protons and 6 neutrons and an atom with 6 protons and 7 neutrons are the isotopes of same element.
<u>Explanation:</u>
Isotopes are defined as the chemical species that belong to the same element but differ in their mass number.
This also means that the chemical species have same number of protons and electrons but different number of neutrons.
Atomic number is defined as the number of protons or electrons that are present in a neutral atom.
Atomic number = number of protons = number of electrons
Mass number is defined as the sum of number of protons and neutrons that are present in an atom.
Mass number = Number of protons + Number of neutrons
From the given options:
The elements having same number of protons will be the isotopes of same element.
Hence, the atom with 6 protons and 6 neutrons and an atom with 6 protons and 7 neutrons are the isotopes of same element.
Answer:
V/V% = 8.2%
Explanation:
Given data:
Volume of methanol = 37.5 mL
Volume of solution = 456 mL
V/V% = ?
Solution:
V/V% = [volume of solute / volume of solution ]×100
V/V% = 37.5 mL / 456 mL × 100
V/V% = 0.08× 100
V/V% = 8.2%
