Answer:

The correct option is A.

Explanation:

A disaccharide refers to a sugar that is formed by the chemical bonding of two monosaccharides which are joined together via glycosidic bond.

A monosaccharide refers to any sugar that can not be reduced further to give a simpler sugar. When two monosaccharides residue come together they form a disaccharide ('Di' means two).

One good example of monosaccharide is glucose. When two glucose molecules or glucose and another monosaccharide join together they give rise to disaccharide such as surcose, lactose and maltose. The components of these disaccharides are given below:

1. Sucrose (Table sugar): Glucose + fructose.

2. Lactose (Milk sugar): Glucose + galactose.

3. Maltose: Glucose + glucose.

What could you do to change the volume of a gas
Jet001 [13]
Solids and liquids have volumes thatdo not change easily. A gas, on the other hand, has a vol- ume thatchanges to match the volume of its container. The molecules in a gas are very far apart compared with the molecules in a solid or a liquid. The amount of space between the molecules in a gas can change easily.

Incomplete question. The remaining part reads;

Choose the correct words or phrases to complete the sentences.

Global winds occur due to

<u>1. Choose...</u>

a. solar currents

b. convection currents

c. sea breezes

d. uneven heating

over a large area and this forms

2. Choose...

a. solar currents

b. convection currents

c. sea breezes

d. uneven heating

caused by cool and warm air.

Answer:

<u>1. d. uneven heating</u>

<u>2. b. convection currents</u>

Explanation:

1. What Beto should know is that as the earth moves and rotates around the sun, some parts of the Earth receive more sunlight and others less, which then leads to uneven heating over a large area of the earth.

2. This uneven heat then forms a convection current containing varying patterns of air spreading to various parts of the globe.

If the reaction of 9.87 moles of potassium with excess hydrobromic acid produced a 79.8% yield of hydrogen gas, what was the act
Fed [463]
Answer is: 3,94 of hydrogen gas.
Chemical reaction: 2K + 2HBr → 2KBr + H₂.
n(K) = 9,87 mol.
n(H₂) = ?.
from reaction: n(K) : n(H₂) = 2 : 1.
9,87 mol : n(H₂) = 2 : 1
n(H₂) = 4,935 mol for 100% yield of reaction
n(H₂) = 4,935 · 0,798 = 3,94 mol for 78,9 % yield of reaction.
