Answer:

0.241 M

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

HBr + NaOH —> NaBr + H₂O

From the balanced equation above,

The mole ratio of acid, HBr (nₐ) = 1

The mole ratio of base, NaOH (n₆) = 1

Finally, we shall determine the concentration of the NaOH solution. This can be obtained as follow:

Volume of base, NaOH (V₆) = 20 mL

Volume of acid, HBr (Vₐ) = 24.1 mL

Concentration of acid, HBr (Cₐ) = 0.2 M

Concentration of base, NaOH (C₆) =?

CₐVₐ / C₆V₆ = nₐ/n₆

0.2 × 24.1 / C₆ × 20 = 1/1

4.82 / C₆ × 20 = 1

Cross multiply

C₆ × 20 = 4.82

Divide both side by 20

C₆ = 4.82 / 20

C₆ = 0.241 M

Therefore, the concentration of the NaOH solution is 0.241 M

P- Pull the pin, this step will allow you to discharge the extinguisher.

A- Aim the nozzle at the base of the fire, If aim at the flames, which is most frequently the temptation, the agent in the extinguisher will fly right through and will do no good,  You had to hit the fuel.

S- Squeeze the lever slowly, In this step depresses the button that releases the pressurized extinguishing agent in the extinguisher.

S- Sweep the spray from side to side over the fire,  Start using the extinguisher from a safe distance away, then move forward to the reduced flame, until the fire is completely out, but keep an eye,  on the area it may re-ignites.

That the pressure doubles when the gas's volume is cut in half.

If gas volume and temperature are maintained constant, the formula demonstrates that pressure and volume are inversely proportional.

This implies that if volume decreases, pressure must increase. This implies that if pressure doubles, volume must be half, and if pressure is halved, volume must be doubled in order to maintain the K value.

If the volume is doubled and the pressure is tripled, the effect on the temperature will be 3 2 = 6 times. This is because for perfect gases, the temperature is directly related to both the volume and the pressure.

The kinetic molecular theory of matter explains the physical properties of matter and how they relate to their molecular structures. This theory states that matter is made up of tiny particles, called molecules, that are always in constant motion, even when in a solid state.

The kinetic molecular theory of matter helps in explaining the properties of matter and how it relates to the molecular structures of matter. According to this theory, the particles that make up matter are in constant motion regardless of their state of matter, and their motion is related to the state of matter they exist in. The theory is divided into three main postulates as follows:1. Matter is made up of tiny particles called molecules that are in constant motion, even when in a solid state.2. The movement of these particles increases with an increase in temperature, resulting in an increase in the kinetic energy of the particles.3.

The collisions between these particles and the walls of the container they are in result in the pressure exerted by the gas. The relationship between heat, energy, and temperature as part of the kinetic molecular theory is as follows:Heat is the transfer of energy between different systems, whereas temperature is the measure of the average kinetic energy of the particles in a system. This means that as heat is transferred into a system, the particles in that system will gain kinetic energy, which will lead to an increase in temperature.

a) The independent variable was the surface area of the limestone (large chips, small chips, and powder).

b) The dependent variable was the rate of the reaction, measured in cm³ of carbon dioxide produced per second.

c) i) Four variables that must be controlled are:

ii) These variables must be controlled to ensure that the only variable affecting the reaction rate is the surface area of the limestone.

The relationship between surface area and the rate of a reaction is that the rate of a reaction increases as the surface area of the reactants increases.

The missing rates can be calculated using the formula:

Rate = Volume of carbon dioxide produced ÷ Time taken to produce it

Size of limestone Time taken (s) Volume of carbon dioxide produced (cm³) Rate (cm³/s)

Large chips 150 50 0.33

Small chips 110 50 0.45

Powder 15 50 3.33

e) The powder had the biggest surface area.

f) The time taken for the reaction to occur decreases as the surface area of the limestone increases.

g) The reaction rate increases as the surface area of the limestone increases.

h) Changing the surface area of the limestone increases the frequency of collisions between the reactant particles (limestone and hydrochloric acid). This increase in the frequency of collisions results in an increase in the reaction rate.

Explanation:

The electrically polar nature of the water molecule, with positive and negative ends, accounts for the fact that water is a very strong solvent.

This polarity allows water molecules to attract and interact with other polar or charged molecules, such as salts, sugars, and acids, and dissolve them easily. However, this property does not directly affect the fact that rivers flow downhill, the fact that water vapor is a very strong greenhouse gas, or the fact that water boils at 100 degrees Celsius.
