Explanation

a.

-Collect healthy cassava stem cuttings of about 25cm long each with a good number of buds/nodes

-Plant the stem cuttings in slanting position or at an angle of 45°

-Bury about 2/3 of the stem cuttings in the soil with the buds facing upwards

-Observe the buds above the soil surface which develop new shoots while the buds buried in the soil develop new roots

b.

-Can be processed into Garri/flakes/chips/flour/tapioca/consumed as food

-Cassava flour is used in baking

-Cassava meal/chips/peels are used as animal feed

-Alcohol can be extracted from the tubers

-Can be processed into starch

-Dextrose can be extracted from the tuber/pharmaceutical uses

-Can be processed into adhesive/glue

ci.

Spacing = 100 cm x 100 cm

1 m = 100 cm

Spacing =1m x 1m =1m2.

Area of farmland = 1.5 ha

1 ha = 10,000 m2

Area of farmland = 1.5 x 10,000 m2

15,000 m2

Expected number of yam plants on the farmland

= Area of farmland/Spacing

15,000 m2 / 1 m2

=15,000 yam plants

cii. Average weight of one yam tuber = 3.5 kg

Total weight of yam tubers harvested 3.5 kg x 15,000=52,500 kg

d. Diet is the amount of feed regularly given or consumed by a farm animal

While

Ration is the amount of feed that is given to a farm animal daily/over a 24 hour period

Correct Answer: D. information management

Correct Answer: D. N14 000

Correct Answer: B. prayed for the cup to pass from him

Correct Answer: B. trivial subject-matter by using the style of the classical epic

Correct Answer: A. A constant change in price

Explanation

The quantity theory of money assumes that the velocity of money is constant. This also means that the inflation rate is equal to the growth rate of the money supply minus the growth rate of output. If the money supply grows at the same rate as output, the price level will be stable.

Correct Answer: A. neutralization

Explanation

The given chemical equation is:

H₃O⁺(aq) + OH⁻(aq) → 2H₂O(l)

Let's analyze the components of the reaction:

• H₃O⁺(aq): This is the hydronium ion, which is characteristic of an acid in an aqueous solution. It represents the proton (H⁺) hydrated by water.

• OH⁻(aq): This is the hydroxide ion, which is characteristic of a base in an aqueous solution.

• H₂O(l): This is liquid water.

The reaction describes the combination of a hydronium ion (from an acid) and a hydroxide ion (from a base) to form water. This is the fundamental reaction that occurs during an acid-base neutralization process in aqueous solution.

Let's evaluate the options:

• A. Neutralization: A neutralization reaction is the reaction between an acid and a base, typically resulting in the formation of water and a salt. The given equation is the net ionic equation for the neutralization of any strong acid by any strong base, or specifically the reaction of the acidic species with the basic species to form water. The heat change accompanying this process is indeed the heat of neutralization.

• B. Formation: The heat of formation is the enthalpy change when one mole of a compound is formed from its constituent elements in their standard states. The given reaction is not forming water from hydrogen gas and oxygen gas, nor is it forming the ions from their elements.

• C. Solution: The heat of solution is the enthalpy change when a solute dissolves in a solvent. The given equation represents a chemical reaction between dissolved ions, not a dissolution process.

• D. Dilution: The heat of dilution is the enthalpy change when more solvent is added to a solution, changing its concentration. The given equation represents a chemical reaction, not a dilution process.

Therefore, the heat change accompanying the reaction H₃O⁺(aq) + OH⁻(aq) → 2H₂O(l) is the heat of neutralization.
