The grams of solute are required.

The mass of solute is 3.5 g

c =  Molarity = 0.1 M

M = Molar mass = 350 g/mol

V = Volume of solution = 100 mL = 0.1 L

n = Number of moles

m = Mass of solute

Molarity is given by

[tex]c=\dfrac{n}{V}\\\Rightarrow n=cV\\\Rightarrow n=0.1\times 0.1\\\Rightarrow n=0.01\ \text{moles}[/tex]

Molar mass is given by

[tex]M=\dfrac{m}{n}\\\Rightarrow m=Mn\\\Rightarrow m=350\times 0.01\\\Rightarrow m=3.5\ \text{g}[/tex]

The mass of solute is 3.5 g

By applying Charles law, the final volume of the gas is equal to 42 mL.

Given the following data:

To find the final volume of the gas, we would apply Charles law:

Charles law states that when the pressure of an ideal gas is kept constant, the volume of the gas is indirectly proportional to the absolute temperature of the gas.

Mathematically, Charles law is given by the formula;

[tex]\frac{V}{T} =k\\\\\frac{V_1}{T_1} = \frac{V_2}{T_2}[/tex]

Where;

Substituting the given parameters into the formula, we have;

[tex]\frac{140}{400} = \frac{V_2}{120} \\\\140 \times 120 = 400V_2\\\\16800 = 400V_2\\\\V_2 = \frac{16800}{400}[/tex]

Final volume = 42 mL.

Explanation:

Using the given information, we can find the amount of grams of hydrogen chloride that take place in the reaction.

Due to the Law of Conservation of Mass, the mass of the system must remain constant. To find the value of x, make the equation below.

[tex]24.30 + x=2.04 + 96.90[/tex]

The left side represent the reactant side of the chemical reaction and the right side represents the product side.

[tex]2.04 + 96.90= 98.94[/tex]

[tex]24.30+x=98.94[/tex]

[tex]24.30 - 24.30 + x= 98.94 - 24.30[/tex]

Matter is neither created nor destroyed. Therefor, option (A) is correct.

The Law of Conservation of Mass is a fundamental principle in science that states that matter cannot be created or destroyed in a chemical reaction, only transformed from one form to another. This means that the total mass of the reactants in a chemical reaction must be equal to the total mass of the products.

The Law of Conservation of Mass was first introduced by Antoine Lavoisier, a French chemist, in the 18th century. The law has been extensively tested and verified through numerous experiments in the field of chemistry. It is an essential concept for understanding the behavior of matter in chemical reactions and for the development of technologies that depend on chemical reactions, such as energy production, medicine, and materials science.

Answer:

An aluminium atom contains 13 electrons.

Answer:

Decreasing the temperature of the copper made the final temperature decrease.

Heat emitted by copper reduces as copper's mass decreases. As the mass of copper lowers due to a decrease in heat gain by water, the final temperature also drops.

The transfer of kinetic energy from an energy source to a medium, an object, or from one to the other is referred to as the creation of heat. The sun is the source of all energies. It is the natural source of solar energy, heat, and light. Thermal energy can move through three different channels: conduction, convection, and radiation.

Therefore, the increase in temperature is always proportionate to the mass of water. Thus, the final temperature will be lower if we increase the water mass. The temperature will be lower in the end. The density reduces as volume grows. Consequently, density drops as temperature rises.

Thus, heat emitted by copper reduces as copper's mass decreases. As the mass of copper lowers due to a decrease in heat gain by water, the final temperature also drops.

Explanation:

Because the atoms in metals form a matrix through which outside electrons may easily travel, metals are good conductors of electricity and heat. They generate a sea of electrons around the positive nuclei of the interacting metal ions, rather than circling their particular atoms.

The free flow of shared electrons can carry an electric current through a metal. Carbon atoms join with iron atoms to create bonds.
