Answer:

[tex]2.686*10^{24}[/tex]

Explanation:

Avogadro's number, 10 x 10^{23}, represens the number of atoms in a single mole of any substance.

Since we already of have the mole amount and don't need to calculate that from the grams of the substance, we can simply multiple Avogadro's number by the amount of moles given.

[tex]4.46 *(6.022*10^{23}) = 2.686 * 10^{24}[/tex]

Answer:

This tells you that when 1 mole of propane undergoes combustion, 3 moles of carbon dioxide are produced. You can thus say that when 2.0 moles of propane react, you will get 2.0moles C3H8 ⋅ 3.moles CO2 1mole C3H8 = 6.0 moles CO2

The force of  friction acting on the block is -2N.

To find the force of a friction, the given datas are,

Force = 6N

Mass = 1 kg

Acceleration = 4 m/s².

The push or pull on an object that made the changes in the velocity with the mass. The object's or body's is to be at motion or at rest will be determined by Force. It has both the magnitude and direction.

The Net Force of the object can be written by:

Fnet = ma

where m is the mass of the object in kg

a is the acceleration of the object in m/s^2

Substituting the values in the formula,

Fnet = (1.0)(4.0)

        = 4 N

We also know that Net force is also the sum of all forces acting on an object. In this case Friction and the Pushing Force is acting on the object. Hence we can write that:

Fnet = Pushing Force + (-Friction)

6N = 4 N - Friction

Friction = - 2N

Hence the force of friction is -2 N.

Answer: 6.97 g

Explanation:

Grams of potassium sulfate must be added to make 200. mL of a 0.200 M potassium sulfate solution are 6.96.

Molarity of a given solution is known as the total number of moles of solute per litre of the solution.  A solution that is 1.00 molar (written 1.00 M) contains 1.00 mole of solute for every liter of solution.

Molarity = (No. of moles of solute ÷ Volume of solution in liters)

The unit of molarity is mol L⁻¹.

Molarity is temperature dependent because as temperature changes, volume of the solution also changes.

No. of moles of solute = 0.04

Mass of potassium sulfate = 174.2 × 0.04

Mass of potassium sulfate = 6.96 grams

Therefore, Grams of potassium sulfate must be added to make 200. mL of a 0.200 M potassium sulfate solution are 6.96.

THE UGLY DUCKLING

The ugly duckling doesn't fit with the other ducklings and grows up, to be a fabulous bird. In the beginning, he is teased because of his looks, in a quote, "As the ugly duckling grew, many animals in the pond criticized him. His feathers were too dark, his neck was too long, and his body was too big. His fellow ducklings refused to recognize that underneath the feathers, the ugly duckling was kind, good, and gentle. The ugly duckling shed many tears because none of the other animals would play with him."

Near the end, however, it states, "He believed that the swans would never be his friends and looked down into the pond in despair. Then, his eyes opened wide, for he saw his reflection. To his great astonishment, the ugly duckling discovered that he was a beautiful, royal swan! The swans welcomed their new friend, whose lovely appearance was matched only by his kind heart. He now felt like he belonged." Throughout the course of the story, the other birds' views change since now they realize how awful they felt for mistreating the ugly duckling.

THE PRINCESS AND THE PEA

The king and queen didn't believe that she was a princess, so they had her endure the trial of sleeping on twenty mattresses with a pea under the very bottom one. Near the beginning of the story, it states, "The disheveled maiden looked at the king in disbelief. "I am a princess, come to see the prince," she explained, all the while shivering. The king summoned his wife, the queen, for advice. The queen looked at the hideous creature in disbelief, thinking that no princess would ever allow herself to be found in such a state. She thought quickly and came up with a clever plan. The queen put a small pea at the bottom of a bed and piled twenty mattresses on top of it. When the girl arrived at the room, she had to climb a ladder to reach the top of the bed, where she collapsed in exhaustion." This is when the king and queen were in doubt that she was a princess.

However later on it stated, "Bright and early the next morning, the king and queen arrived at the girl's bed-chamber. The queen asked the girl how she had slept the night before. "Absolutely terribly!" bemoaned the maiden. "I have spent the entire night tossing and turning. I don't know whether there is something hard in the bed, or your mattresses are rocks, but my body is black and blue." The queen and the king stared at the maiden in astonishment. Only a real princess would have such delicate skin that she could feel a pea under twenty mattresses. The queen and king brought her to the prince, who was thrilled to meet a real princess with such an independent spirit." As you can see the king and queen believed that she was a princess now because they stated, "Only a real princess would have such delicate skin that she could feel a pea under twenty mattresses."

Answer

adding an acid to water increases the concentration of the H3O+ ion. decrease in the concentration of the OH- ion.

Explanation/ complete answer

Adding an acid to water therefore has an effect on the concentration of both the H3O+ and OH- ions. Because it is a source of this ion, adding an acid to water increases the concentration of the H3O+ ion. Adding an acid to water, however, decreases the extent to which water dissociates. It therefore leads to a significant decrease in the concentration of the OH- ion.

16 cells are produced from a single parent cell after fourth division of cell.

During mitosis type of cell division, one parent cell is divided into two daughter cells. In this way, in the first division two cells are produced from single parent cell, in the second division four daughter cells are produced. In the third division, 8 cells are produced from 4 parent cells and in the fourth division 16 cells are formed from 8 cells.

So we can conclude that 16 cells are produced from a single parent cell after fourth division of cell.
