Does a solution have to involve a liquid? Explain your answer

Answers

Answer 1

Answer: not actually because a solution in math also involves the answer as well as physics.

Answer 2

Answer:

Final answer:

A solution is a homogeneous mixture and does not necessarily have to include a liquid component. It can exist in gas, liquid, and solid states. Examples include air (a gas solution) and alloys (a solid solution).

Explanation:

No, a solution doesn't always have to involve a liquid. This is a common misunderstanding because water is often used as a solvent, which leads many to associate solutions with liquids. However, solutions can exist in all states of matter: gas, liquid, and solid.

A solution is a homogeneous mixture of two or more substances. The substance present in the largest quantity is usually the solvent, and substances in lesser amounts are the solutes.

For instance, air is a gaseous solution involving nitrogen, oxygen, and various other gases. Alloys, like the nickel dissolved in copper in US five-cent coins, are examples of solid solutions. Therefore, while often associated with liquids, solutions can exist across various physical states.

The exercise is to measure and record the Physical properties of materials, such as flexibility, magnetism, thermal conductivity, electrical conductivity and density. Magnetism and flexibility can be observed directly, while density, thermal conductivity, and electrical conductivity require calculations.

The student is asked to measure and record the physical properties of various materials.

Flexibility can be rated subjectively on a scale of 1-10, with 10 being most flexible.

Magnetism can be tested by seeing how many paper clips each material can hold.

Thermal Conductivity (W/(m·K)) is a measure of a material's ability to conduct heat, while Electrical Conductivity (x107 S/m) measures the material's ability to conduct electricity.

For density, you need the mass (M) and volume (V) of the material.

The mass is given as 10g for all materials. You have to measure the volume (V) using the formula length x width x height (L x W x H).

Then plug M and V into the density formula D=M/V to get the density in g/cm3. Keep in mind that each material will have different properties.

When 25.0 mL of sulfuric acid solution was completely neutralized in a titration with 0.05 M NaOH solution, it took 18.3 mL of the NaOH(aq) to complete the job. The reaction is:NaOH(aq) + H2SO4(aq) → Na2SO4(aq) + H2O(l)
What was the molarity of the sulfuric acid solution?

Answers

Balanced equation will be as follows

2NaOH + H2SO4=Na2SO4 + 2H2O
from MaVa/MbVb=Na/Nb where Ma is molarity of acid=?
Va is volume of acid=25.0 mL
Mb is molarity of base= 0.05 M
Vb is volume of base=18.3 mL
Nb number of moles of base= 2
Na is number of moles of acid =1

Ma*25 mL / 18.3mL*0.05M = 1/2
Ma=18.3*0.05M / 50 = 0.0183M

The molarity of sulphuric acid = 0.0183M

Final answer:

The molarity of the sulfuric acid solution is found using the formula: M1V1/2 = M2V2 to account for the 2:1 ratio of NaOH to H2SO4 in the reaction. Substituting the given values yields the molarity of sulfuric acid solution as 0.0732M.

Explanation:

This problem involves a concept known as titration, specifically acid-base titration. In this process, one solution (in this case, the base NaOH) is added to another solution (the acid H2SO4) until the mixture is neutralized. The balanced chemical equation NaOH + H2SO4 -> Na2SO4 + 2H2O tells us that the reaction occurs in a 2:1 ratio of NaOH to H2SO4.

To find the molarity of the sulfuric acid, we use the formula: M1V1 = M2V2, where M1 is the molarity of the NaOH, V1 is the volume of the NaOH, M2 is the molarity of the H2SO4 (which we want to find), and V2 is the volume of the H2SO4. However, we need to adjust the equation to M1V1/2 = M2V2 because the reaction occurs in a 2:1 ratio of NaOH to H2SO4.

So substituting the given values into the equation, we have (0.05 M * 18.3 mL) / 2 = M2 * 25.0 mL. Solving for M2, the molarity of the sulfuric acid solution, yields M2 = 0.0732M.

If 1 bus = 12 cars, 3 cars = 1 truck, and 1000 basketballs = 1 truck, how many basketballs can be carried by 8 buses?

Answers

The factor label method (dimensional analysis) is a method used to solve problems by the given amount and value. Eightbuses can carry 32,000 basketballs.

What is dimensional analysis?

Dimensional analysis has been also called the unit factor method used to convert the various units and quantities by mathematical computation and equation formation. It can convert the fundamental and derived units.

Given,

1 bus = 12 cars

3 cars = 1 truck

1 truck = 1000 basketballs

If 3 cars have been equal to 1 truck then, 12 cars will be equal to X trucks

Solving for X as:

X = (12 cars × 1 truck) ÷ 3 cars

= 4 trucks

Hence, 4 trucks are equal to 12 cars.

Now, from above it can be said that 1 bus has been equal to 4 trucks.

So, if one bus = 4000 basketballs

8 bus = X basketballs

Solving for X:

X = 4000 × 8

= 32000 basketballs

Therefore, eight buses can contain 32000 basketballs.

Which substances dissolves in pure water and produces a solution that is a good conductor of electricity?1) CaCl2
2) C6H12O6
3) N2
4) O2

Answers

Answer:

$CaCl_2$

Explanation:

We have to keep in mind that a good conductor would be a substance that has the ability to produce ions (charged species). These species are responsible for the electricity conduction on water.

Therefore, we have to check which ones of these compounds will produce ions in water. For $N_2$ and $O_2$ we have diatomic molecules (also gases) this type of molecules don't have the ability to produce ions due to his simplicity, they already are very stable.

In the sugar molecule $C_6H_12O_6$ we have a covalent compound. The ions are produced by ionic compounds. So, this molecule can be discarded too.

For $CaCl_2$ we have an ionic compound that have the ability to produce ions:

$CaCl_2~~->~~Ca^+^2~+~2Cl^-$

So, this is the compound that would be a good conductor due to the $Ca^+^2$ and the $Cl^-$ ions.

CaCl2 is a good conductor of electricity when dissolved in water.
