There are three things you can do to dissolve the salt in water:
1) Stir the solution - you increase the rate at which water molecules will come in contact with the salt crystals
2) Grind the salt - the surface area of the salt will increase thus the contact area between ionic lattice of the crystal that can interact with water, is bigger
3) Increase the temperature - this will increase even more the rate of the solvation by increasing the kinetic energy of the particles
Explanation:
Equation of the reaction:
H2X(aq) + 2NaOH(aq) --> Na2X + 2H2O
Mass of acid = 0.178 g
Number of moles = molar concentration * volume
= 0.095 * 25.20 mL⋅1 L/1000 mL
= 0.00239 mol
From the equation of reaction,
2 moles of NaOH neutralises in 1 mole of H2X.
Therefore,
0.00239 mole of NaOH, number of koles of H2X = 2 * 0.00239 mol
= 0.0012 mole.
Molar mass = mass/number of moles
= 0.178/0.0012
= 148.7 g/mol.
Answer: A resource which we get naturally from the enviornment such as, air water, soil etc. is known as natural resources. Natural resources can be categories on the basis of renewability and it is of two types; renewable and non-renewable.
A natural capital is the stock of natural resources; which includes soil, air and all the living organisms present on this planet
