Answer:

B) Thomson's Model

Explanation:

Dalton's Model simply consisted of small spheres that represented atoms, and Bohr's model had a nucleus in the center with electrons orbiting in strict orbits, not randomly spread throughout. Thomson's plum pudding model, however, had an overall positively charged atom with many electrons spread throughout. If you search up "Plum Pudding Model" you can visually understand this.

Answer:

the answer is 70.906 g/mol

Explanation:

Answer:

214.12 g

Explanation:

mass = no. of moles x molar mass

molar mass of Cl2 = atomic mass of Cl x 2

= 35.453 x 2

=70.906

so the mass of 3.02 mol Cl2 = 3.02 x 70.906

=214.12 g

Answer:

Explanation:

This question describes Charles law, which shows the direct relationship of the absolute temperature to its volume when the pressure is kept constant. The Charles' law equation is:

V1/T1 = V2/T2

Where; V1 is the volume of the gas at an initial state

V2 is the volume of the gas at a final state

T1 is the absolute temperature of the gas at an initial state

T2 is the absolute temperature of the gas at a final state.

According to the question, V1 = 2.33L, V2 = ?, T1 = 10°C, T2 = 100°C

The absolute temperature unit, which is Kelvin, need to be used. Hence, we convert °C to Kelvin using:

T(K) = T(°C) + 273.15

T1 (K) = 10°C + 273.15 = 283.15K

T2 (K) = 100°C + 273.15 = 373.15K

To solve for V2 in the above Charles law equation, we make V2 the subject of the formula by saying:

V2 = V1 × T2 / T1

V2 = 2.33 × 373.15 / 283.15

V2 = 869.4395/ 283.15

V2 = 3.0705

Hence, the gas will be expanded to a volume of 3.07L when heated from 10.0°C to 100.0°C.

The statement that is true from the following is catalysts are important to the industry to increase product yields. The correct option is C.

Catalysts are substances that speed up or increase the rate of reaction. The biological catalysts are enzymes. Enzymes are made up of proteins, and they are used in the reaction to increase the yield in less time. Catalyst does not mix with the process and after the reaction.

There are many chemical catalysts like nickel and iron. These catalysts are used in chemical and manufacturing processes. They impact, accelerate, and promote the reaction to get different yields.

Thus, the correct option is C. Catalysts are significant to industry to increase product yields.

Answer:

A carbon–carbon bond is a covalent bond between two carbon atoms.

Explanation:

Answer:

A) open switch

Explanation:

it is an open switch, seeing that when the switch is open, there is a gap between the wire and switch preventing any electric current from flowing. A closed switch is the opposite.

The flow of current is needed to be circuit closed. The electrons are starts following form one end to other end. The lack of current in the circuit is due to open switch.

Current is said to be the flow of electrons in an electric circuit. The electrons starts flow is mainly due to potential difference.

Current is represented by I.

SI unit of current is Ampere.

In home, the circuit is designed in such a way that, the flow of electricity is controlled by switch. If switch is off mode, there is no electricity flow and glow light or electrical application.

Voltage is the difference in electric potential between two points. Current is just the rate of flow of electric charge.

Option A. 416.1 g.

Explanation:

Data obtained from the question include the following:

Molarity = 1.743 M

Volume = 1.4957 L

Mass of CuSO4 =..?

Next, we shall determine mole of CuSO4 present in the solution.

This is illustrated below:

Molarity is simply defined as the mole of solute per unit litre of the solution. Mathematically, it is expressed as:

Molarity = mole /Volume

With the above formula, we can obtain the mole CuSO4 present in the solution as follow:

Molarity = 1.743 M

Volume = 1.4957 L

Mole of CuSO4 =..?

Molarity = mole /Volume

1.743 = mole of CuSO4 /1.4957

Cross multiply

Mole of CuSO4 = 1.743 x 1.4957

Mole of CuSO4 = 2.607 moles

Finally, we shall convert 2.607 moles of CuSO4 to grams.

This can be obtained as follow:

Molar mass of CuSO4 = 63.55 + 32.06 + (16x4) = 159.61 g/m

Mole of CuSO4 = 2.607 moles

Mass of CuSO4 =..?

Mole = mass /molar mass

2.607 = mass of CuSO4 /159.61

Cross multiply

Mass of CuSO4 = 2.607 x 159.61

Mass of CuSO4 = 416.1 g

Therefore, 416.1 g of CuSO4 is needed to prepare the solution.

Answer:

A) Molecule A: Fatty acid

Molecule B: Glycerol

B) 3 molecules of molecule A(fatty acid) normally combine with one molecule of B (glycerol) to form a single fat molecule

Explanation:

QUESTION A:

Fats/lipids are one of the four major biomolecules in living systems. They are polymers, and like any polymer, they are made up of monomeric units which serve as building blocks. In the case of fats/lipids, fatty acids and glycerol are the two major building blocks.

Fatty acids are biological compounds made up of a hydrocarbon chain with a terminal carboxyll group (-COOH), which confers its acidic properties upon it. Hence, based on the structural diagram of molecule A in the attached image, it can be observed that the functional group is a carboxyll group. Therefore, molecule A is a FATTY ACID.

Glycerol is a compound with more than one hydroxyll group (-OH) in its chemical structure. It has the chemical formula; C3H8O3 with three hydroxyll groups attached to each of the carbon atoms. Therefore, as observed in the image, molecule B is a GLYCEROL because it contains 3 hydroxyll groups.

QUESTION B:

In the chemical structure of a fat molecule, three fatty acids are attached to each of the three carbon atoms of the glycerol molecule. This is done through the process of esterification i.e. combination of carboxyll group with hydroxyll group. Due to the fact that it takes 3 molecules of fatty acids to combine with one molecule of glycerol, fats are referred to as triglycerides.
