Answer:
A. 1.50 M
Explanation:
Concentration is the number of moles of solute dissolved in a volume of 1 L of solution
Mass of LiBr - 97.7 g
Number of moles of LiBr - 97.7 g /87 g/mol = 1.12 mol
Equation for concentration is as follows
Concentration = number of moles / volume of solution in L
Substituting the values
Concentration = 1.12 mol / 0.7500 L
Concentration of LiBr is 1.50 mol/L
Answer:
Chemical weathering.
Explanation:
Chemical weathering has more to do with weathering things with acid, water, and air. Mechanical weathering happens without water most of the time. Yes they both have water weathering but Chemical weathering has a higher rate of impact.
Energy in a chemical reaction is not created nor destroyed, it's always conserved based on the law of conservation of energy.
Answer:
Clayey soil is rich in humus and very fertile, so it is suitable for growing cereals like wheat and gram. Such soil is good at retaining water.Clayey is known to be useful for crops. Because the particle size in this soil is very fine, it has the ability to retain more amounts of water. - This makes it easy for crops to access water as it is very essential for the growth of the plant. - Some of the crops need a high amount of water in order to grow.Clayey soil is made up of fine particles that are tightly packed and increases soil density and strength. It is rich in nutrient content in the form of organic matter or humus so, it is very fertile soil. It has excellent water retaining a capacity.
Thermal expansion is the tendency of matter to change its shape, area, volume, and density in response to a change in temperature, usually not including phase transitions. Temperature is a monotonic function of the average molecular kinetic energy of a substance.
