Answer:

Read this passage from Through the Looking-Glass.

She looked at the Queen, who seemed to have suddenly wrapped herself up in wool. Alice rubbed her eyes, and looked again. She couldn't make out what had happened at all. Was she in a shop? And was that really—was it really a SHEEP that was sitting on the other side of the counter? Rub as she could, she could make nothing more of it: she was in a little dark shop, leaning with her elbows on the counter, and opposite to her was an old Sheep, sitting in an arm-chair knitting, and every now and then leaving off to look at her through a great pair of spectacles.

“What is it you want to buy?” the Sheep said at last, looking up for a moment from her knitting.

“I don't QUITE know yet,” Alice said, very gently. “I should like to look all round me first, if I might.”

“You may look in front of you, and on both sides, if you like,” said the Sheep: “but you can't look ALL round you—unless you've got eyes at the back of your head.”

The tone of this passage is best described as

serious and reflective.

scientific and factual.

Answer:

1. 111.54 kJ

2. 944.68 kJ

3. 339 kJ

4. 94.92 kJ

5. 21.0578 kJ

Explanation:

1. The heat required to melt a given quantity of ice is known as the latent heat of fusion, [tex]L^{\circ}_F[/tex], of ice

[tex]L^{\circ}_F[/tex], of ice = 330 J/g

The heat required to melt a given mass of ice = Mass of ice, m × latent heat of fusion, [tex]L^{\circ}_F[/tex], of ice

The heat required to melt 338 grams of ice = 338 g × 330 J/g = 111,540 J = 111.54 kJ

2. The latent heat of vaporization, l, of water = 2260 J/g

The heat required to convert, m grams of water to steam at

The heat required to convert 418 grams of boiling water into steam = 418 g × 2260 J/g = 944680 J = 944.68 kJ

3. To convert 150 grams of boiling water to steam, we have;

Heat required = 150 g × 2260 J/g = 339,000 J = 339 kJ

4. To convert 42.0 grams of boiling water to steam, we have;

Heat required = 42.0 g × 2260 J/g = 94,920 J = 94.92 kJ

5. The specific heat capacity of steam is 1.996 J/(g·°C)

The heat, Q, required to raise a given mass, m, of steam by Δt °C is given as follows;

Q = m × c × Δt

The heat required to raise the temperature of 422 grams of steam from 110.0 °C to 135.0 °C is therefore;

Q = 422 g × 1.996 J/(g·°C) × (135.0 °C - 110.0 °C) = 21057.8 J

The heat required to raise the temperature of 422 grams of steam from 110.0 °C to 135.0 °C = 21057.8 J = 21.0578 kJ

Answer:

Explanation:

Any substance that contains only one kind of an atom is known as an element. Because atoms cannot be created or destroyed in a chemical reaction, elements such as phosphorus (P4) or sulfur (S8) cannot be broken down into simpler substances by these reactions.

Example: Water decomposes into a mixture of hydrogen and oxygen when an electric current is passed through the liquid. Hydrogen and oxygen, on the other hand, cannot be decomposed into simpler substances. They are therefore the elementary, or simplest, chemical substances - elements.

Each element is represented by a unique symbol. The notation for each element can be found on the periodic table of elements.

The elements can be divided into three categories that have characteristic properties: metals, nonmetals, and semimetals. Most elements are metals, which are found on the left and toward the bottom of the periodic table. A handful of nonmetals are clustered in the upper right corner of the periodic table. The semimetals can be found along the dividing line between the metals and the nonmetals.

Explanation:

In the portion of the cell membrane shown in the diagram, the arrow indicates the process of active transport.

Explanation:

Active transport is one of the mechanisms of transmembrane transport, which involves the use of energy. The diagram (see image) shows the hydrogen (H⁺) output from the cytoplasm to the extracellular space, through an H⁺ pump —consuming ATP— which represents an active transport process.

The hydrophobic nature of the cell membrane prevents the free passage of hydrosoluble elements or ions, as H⁺, so they require the use of active transport to pass through it.

The other options presented are not correct, because

Respiration is a process that occurs in the mitochondria.

Diffusion is a passive transport process that does not require energy.

Cellular recognition depends on membrane proteins that act as specific receptors.

Answer:the answer is active transport

Distance is the total length of path one travels.

Displacement is the distance between the initial and final position.

 For example, if your classroom is located 200m from your dormitory, you walk to class and back to your dormitory, your distance is 200m + 200m  = 400m;

  Your displacement is 0m. Your initial and final position is the same so no displacement.

(moles SO₂ ) ??---------------- 5.0 g

( moles SO₂) = 5.0 * 1 / 64.066

(moles SO₂) = 5.0 / 64.066

Explanation:

Answer:

When two or more substances, that do not react chemically, are blended together,

the result is a mixture in which each component retains its individual identity and

properties.

The separation of the components of a mixture is a problem frequently encountered

in chemistry. The basis of the separation is the fact that each component has a

different set of physical and chemical properties. The components are pure substances

which are either elements or compounds. Under the same conditions of pressure and

temperature, the properties of every sample of a pure substance are identical. Each

sample melts at the same temperature, boils at the same temperature, has the same

solubility in a given solvent, etc.

Answer: the answer is 2g because you subtract 32-34 and get 2 and add the get so 2g

Explanation:

2 g of hydrogen reacts with 32 g of oxygen to produce 34 g of hydrogen peroxide.

To determine the amount of hydrogen that reacts with 32 g of oxygen to produce 34 g of hydrogen peroxide ([tex]H_2O_2[/tex]), we need to apply stoichiometry.

First, we find the molar masses:

Molar mass of oxygen ([tex]O_2[/tex]) = 16 g/mol

Molar mass of hydrogen peroxide ([tex]H_2O_2[/tex]) = 34 g/mol (given)

Next, we calculate the number of moles for oxygen and hydrogen peroxide:

Moles of oxygen = mass/molar mass = 32 g / 16 g/mol = 2 moles

Moles of hydrogen peroxide = mass/molar mass = 34 g / 34 g/mol = 1 mole

Since hydrogen peroxide has two hydrogen atoms, it requires twice the moles of hydrogen. Therefore, the moles of hydrogen required are also 2 moles.

Finally, we convert the moles of hydrogen to grams:

Mass of hydrogen = moles × molar mass = 2 moles × 1 g/mol = 2 g

So, 2 g of hydrogen reacts with 32 g of oxygen to produce 34 g of hydrogen peroxide

Answer:

Ajay should pass electric current through the water and connect a bulb to the circuit. If the bulb glows, it means that the water is tap water or else, it is distilled water.

Explanation:

This is because tap water contains little impurities like ions of some salts etc., which help in the conduction of electricity. But, distilled water is pure water and doesn't have any ions present in it. So, it doesn't conduct electricity.

Hope this helped

Ajay can test the distilled water by performing the electricity conduction test.

Distilled water has been the water that has an absence of ions and electrolytes. It has been a poor conductor of electricity.

The tap water has been constituted with minerals, electrolytes, and impurities, which results in the addition of conductivity to the water.

To test whether the water has been distilled or not, the circuit test can be performed The water has dipped wires connected with a battery and a bulb. the distilled water is a poor conductor did not allow the bulb to glow. However, with tap water bulb glow.

Thus, to test the water to be distilled or tap, the electricity conduction test has been performed.

Explanation:

condensate is an endothermic change

Answer:

It is the temperature at which a substance changes from a liquid to a solid.

Have a good day!

The temperature at which a substance  changes from a liquid to a solid is called  its freezing point. Hence, option d is the correct definition of freezing point.

Freezing point is a physical property of a substance which measures the temperature at which its liquid state converts to solid state where, the two phases are in equilibrium.

For example, water freezes at 0 degree Celsius to form ice. Hence, 0°C is the freezing point of water. The freezing point of substance is affected by the bond type, molecular weight, temperature and pressure as well the impurities if any.

The more the intermolecular forces between the molecules, more easy to convert it into solid. Hence, the freezing point will be lower. If there is any impurities present, the freezing point depression will occurs.
