Which statement best describes insoluble substances? Insoluble substances remain the same when in water. Insoluble substances become part of the liquid substance. Water does not remain when an insoluble substance is added. Insoluble substances change from solid to liquid states.

Answers

Answer:

Insoluble substances remain the same when in water.

Explanation:

When a substance is regarded as insoluble, it means that the substance remains the same in water.

Soluble substances usually form one continuous phase with water when they are added to water (eg when salt is added to water).

However, when camphor is added to water, it does not form a single phase with water. It remains the same in the water and maintains a separate phase from the water. Hence camphor is an insoluble substance.

One of the uses of methanol (CH3OH) in dilute form is as a windshield washer antifreeze. In pure form, methanol has a molar concentration of 24.7M. How many moles are contained in 500 mL of solution?

Answers

Mol of methanol =12.35Further explanation

Mole itself is the number of particles contained in a substance

1 mole = 6.02.10²³ particles

Mole : the ratio of the amount of substance mass and its molar mass

[tex]\large{\boxed{\boxed{\bold{mole=\frac{mass}{molar\:mass}}}}[/tex]

Molarity is a way to express the concentration of the solution

Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution

11. How many moles are in 7.14 X 10 35
molecules of 02?

Answers

Answer:

The answer is 1.186 × 10¹² moles

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\[/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question

N = 7.14 × 10^35 molecules of O2

We have

[tex]n = \frac{7.14 \times {10}^{35} }{6.02 \times {10}^{23} } \\ [/tex]

We have the final answer as

1.186 × 10¹² moles

According to the given excerpt, independent variable is 'wing length' and dependent variable is 'amount of time it takes for helicopter to hit the floor'.

Independent variable refers to the variable that do not undergo any change or shift in the course of the experiment of research. The other variables are measured using the constant independent variable. The value obtained from the independent variable is independent. On the other and, the dependent variable witnesses change with respect to the independent variable.

Jakasia needed to find the volume of a plastic container in L to see if the 170 L of
solution that she had would fit inside. She knew that one side was 2.5 ft, the
height of the box was 60 cm, and width of the box was 0.8 m. Use dimensional
analysis to determine if Jakasia's solution will fit in the container.

Answers

Answer:

The solution will fit into the container.

Explanation:

The following data were obtained from the question'

Volume of solution = 170 L

Length of container (L) = 2.5 ft

Height of container (H) = 60 cm

Width of container (W) = 0.8 m

Volume of container (V) =?

Next, we shall express the length, height and breadth I the same unit of measurement. In this case, we shall all in centimetres (cm).

For the length:

1 ft = 30.48 cm

Therefore,

2.5 ft = 2.5 ft × 30.48 cm / 1 ft

2.5 ft = 76.2 cm

Thus the length is 76.2 cm

For the width:

1 m = 100 cm

Therefore,

0.8 m = 0.8 m × 100 cm / 1 m

0.8 m = 80 cm

Thus, the width of the container is 80 cm.

Next, we shall determine the volume of the container as follow:

ength of container (L) = 76. 2 cm

Height of container (H) = 60 cm

Width of container (W) = 80 cm

Volume of container (V) =?

Volume = length × width × height

Volume = 76.2 × 80 × 60

Volume = 365760 cm³

Finally, we shall convert 365760 cm³ to litre (L). This can be obtained as follow:

1000 cm³ = 1 L

Therefore,

365760 cm³ = 365760 cm³ × 1 L/ 1000 cm³

365760 cm³ = 365.76 L

Therefore, the volume of the container is 365.76 L

Since the volume of the container (i.e 365.76 L) is bigger than the volume of the solution (i.e 170 L), therefore, the solution will fit into the container.

Which is the best way to determine if an object is made of pure silver?
O Determine the solubility of the object.
O Test to see if the object is chemically reactive.
Determine the density of the object and compare the known density of pure silver.
O Compare the mass of the silver object to the mass of a piece of pure silver.

Answers

Answer:

The correct option is;

Determine the density of the object and compare the known density of pure Silver

Explanation:

The density of the object is found by finding the weight of the object, and then finding the volume (of water) the object displaces when it is immersed (in water)

The  density is then fond by dividing the weighed mass by the volume the object displaces when immersed

Compare the result of the measured density with that of pure silver. If the two have density, as well as other similar physical characteristics, then the object is likely to be pure silver.

A trucker is driving from New Jersey to California to make a delivery of couches. He forgets to adjust the pressure of his tires before his trip and end up blowing out two of his tires while driving through Arizona. Whose law does this example depict? What does this law state? Use the law to explain what happened to the tires.

Answers

Answer:

Gay-Lussac's law.

Explanation:

According to Gay-Lussac's pressure law, it states that the pressure of a given mass of gas is directly proportional to the absolute temperature of the gas, the assumption that the volume is kept constant.

Hence, the trucker's tires were blown up because they were under high pressure as he drove from New Jersey to California, as a result of this intense pressure the temperature of the air in the tires began to rise and it directly affected the pressure of the gas in the tires' tubes which also increased to a point that they ended up blowing out, obeying Gay-Lussac's law.

What information does not need to be included a chemical waste label? Select one: Relative amounts of chemical compounds in the container. The date the waste container was filled completely. A description of the experiment the chemicals were used for. Names of the chemical compounds present in the container.

Answers

Answer:

A description of the experiment the chemicals were used for.

Explanation:

A chemical waste label is required to provide information about any hazardous waste present in the container. Some details are mandatory to mention of the chemical waste label to prevent any accident while doing the experiment, that includes:

Chemical compound's name present in the container.Composition and physical state of the waste.Hazardous properties of the waste.The date of manufacturing.Amount of chemical compounds filled in the container.

A chemical waste label does not mention or describe the experiment for which the chemicals were used for, scientists, teacher or students should have knowledge of the chemical composition by reading their names and evaluate themselves on which chemical should be used for which experiment.

Hence, the correct answer is  "A description of the experiment the chemicals were used for."

The correct answer is A description of the experiment the chemicals were used for.

A chemical waste label must contain all the information about any hazardous waste present in the container. It should clearly indicate the composition of the waste, the date of manufacturing and the amount of chemical compounds filled in the container. A chemical waste label does not need to mention the experiment for which the chemicals were used.
