Answer:
Volume in L = 0.028 L
Explanation:
Given data:
Mass of copper phosphate = 27.6 g
Molarity solution = 6.03 M
Volume of solution = ?
Solution:
First of all we will calculate the number of moles of copper phosphate.
Number of moles = mass/molar mass
Number of moles = 27.6 g/ 159.61 g/mol
Number of moles = 0.17 mol
Volume of solution:
Molarity = number of moles / volume in L
By putting values,
6.03 M = 0.17 mol / volume in L
Volume in L = 0.17 mol / 6.03 M
Volume in L = 0.028 L
Water is amphoteric with both the acidic and basic characters.
<u>Explanation:</u>
As per the Bronsted Lowry theory of acids and bases,
Water has its own ability to either donate or accept hydrogen ions or protons.
- If it accepts a proton then it is termed as basic
- To accept a proton it should have a lone pair of electrons.
- If it donates a proton then it is termed as acidic
- If the water has the ability to accept as well as donating proton then it has both the acidic and basic characters and so it is termed as amphoteric in nature.
An endothermic reaction is the opposite. This is when a reaction starts colder and ends up hotter, taking in energy from start to finish. In an endothermic reaction, the system gains heat as the surroundings cool down. In an exothermic reaction, the system loses heat as the surroundings heat up.
It is either a proton or a neutron . B

How to identify the particle</h3>
The particle labeled with an X is a neutral atom or a proton which is symbolically represented as :
AZX
where,
Z = atomic number of the element and is known as the number of protons and number of electron (in the particle)
A = Mass number of the element which is represented as the sum of the protons and neutrons (in the nucleus)
Thus, the statement that best identifies the particle X is that it is either a proton or a neutron
