Atoms are the individual particles that make up all matter, while molecules are formed when atoms combine together through chemical bonding. There are 6 atoms in NH₄Cl and 5 atoms in CaClO₃.

Atoms are the basic building blocks of matter. They are the smallest units of an element that retain the chemical properties of that element. Atoms consist of a nucleus containing positively charged protons and neutral neutrons, surrounded by negatively charged electrons in energy levels or shells.

Molecules, on the other hand, are formed when two or more atoms chemically bond together. They can be made up of atoms of the same element or different elements. Molecules can exist as discrete units and can have distinct chemical and physical properties. Examples of molecules include water (H2O), carbon dioxide (CO2), and glucose (C6H12O6).

Therefore, there are 6 atoms in NH₄Cl and 5 atoms in CaClO₃ as listed in the table attached.

The fluids seperated because of the different density of the liquids. The lower liquid has a high density while the liquid on top has a low density

Group 16 elements  have 6 valence electrons in the periodic table.

It is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.

Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.

Answer:

They have like charges

Explanation:

Like charges repel, opposite charges attract

The most likely reason the comb is able to repel the balloon is that, the balloon and the comb have the same electrical charge.

The question is incomplete, the complete question is;

One student rubs a balloon against his hair several times. Another student passes a comb through her hair several times. The students place the comb near the balloon and observe that the comb repels the balloon. Which is the most likely reason the comb is able to repel the balloon?

A.The balloon has a positive charge and the comb is neutral.

B. The balloon and the comb have the same electrical charge.

C. The balloon has a negative charge and the comb is neutral.

D. The balloon and the comb have opposite electrical charges

When the student rubs a balloon against his hair several times or another student passes a comb through her hair several times, static charges are built up on the balloon and the comb.

One of the ways by which a neutral object can be charged is by friction. That is, rubbing it against another object repeatedly.

The fact that when the students place the comb near the balloon and observe that the comb repels the balloon means that both the comb and the balloon acquired the same kind of charge after friction.

Therefore, the balloon and the comb have the same electrical charge.

Answer:

c) non polar Covalent

Explanation:

this is a molecule formed by atoms of the same element . they both have similar electronegativities and thus cancel out . This makes it a perfect Covalent molecule . The fact that it's a symmetrical molecule makes it non polar. a symmetrical molecule is a molecule formed by the overlap of orbitals of two atoms of the same element ( that is to say , there's no dipole )

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

Explanation: i stuck at this Answer:Sometimes atoms share more than one pair of electrons, for example a double covalent bond can occur, as in the carbon dioxide molecule where carbon shares 2 pairs of electrons with each oxygen atom: O=C=O. (where = represents a double bond). Another kind of covalent bonding is called co-ordinate or dative covalent.

A polar covalent bond exists between the atoms in a CO2 molecule. A carbon atom is joined by four covalent bonds to two oxygen atoms, each of which has two covalent bonds.

A chemical bond is a long-lasting attraction between atoms, ions, or molecules that allows chemical compounds to form.

Ionic bonds are formed by the electrostatic force between oppositely charged ions, whereas covalent bonds are formed by the sharing of electrons.

One carbon atom and two oxygens combine to form the carbon dioxide molecule.

Carbon has only four outer shell electrons, whereas oxygen has six. Double covalent bonds form between the atoms, with two electrons from each atom shared, for a total of four bonding electrons.

A CO2 molecule contains polar covalent bonds between its atoms. Four covalent bonds connect a carbon atom to two oxygen atoms, each of which has two covalent bonds.

Thus, this way bond gets formed between carbon and oxygen atoms.

Answer:

The extraction is done by electrolysis. The ions in the aluminum oxide must be free to move so that electricity can pass through it. Aluminum oxide has a very high melting point (over 2000°C) so it would be expensive to melt it. Aluminum oxide does not dissolve in water, but it does dissolve in molten cryolite.

Answer: A.) The reactant that is used up first in a reaction

The reactant that is totally consumed during a reaction, or the limiting reagent, decides when the process comes to an end. A limiting reagent is the reactant that is used up first in a reaction. Therefore, option A is correct.

A reactant that is completely consumed at the end of a chemical reaction is known as the limiting reagent. Since the reaction cannot proceed without this reagent, the amount of product that can be produced is constrained.

The limiting reactant is the one that is consumed first and sets a limit on the quantity of product(s) that can be produced. Calculate how many moles of each reactant are present and contrast this ratio with the mole ratio of the reactants in the balanced chemical equation to get the limiting reactant.

The terms limiting reagent and limiting agent may also be used to describe the limiting reactant.

Thus, option A is correct.
