When a fluorine atom becomes an ion, it will
A) gain an electron and increase in size
B) lose an electron and increase in size
C) gain an electron and decrease in size
D) lose an electron and decrease in size

Answers

Answer 1

Answer:

A) gain an electron and increase in size

Explanation:

Fluorine is a Group 17 element, making it a halogen. This means that it has 7 valence electrons in its outer shell. It only needs one more electron to fill its outer shell and gain stability. When fluorine becomes an ion, it gains an electron and becomes F⁻. Adding electrons creates a larger ion because the electrons occupy a larger volume due to mutual repulsions pushing them apart.

Hope that helps.

Answer 2

When a fluorine atom becomes an anion, it will gain an electron and increase in size. Therefore, option (A) is correct.

What is an ion?

An ion is a chemical specie that holds a positive or negative charge. The term ‘ion’ refers to atoms or molecules with non-zero net charges associated with them. Therefore, all ions have either a greater number of electrons than protons in their atomic structures or a greater number of protons than electrons.

If the number of protons is greater than electrons are termed to hold a net positive charge and are commonly referred to as cations. The ions that contain a greater number of electrons than protons hold a net negative charge and are known as anions.

The electronic configuration of the fluorine is 1s²2s²2p⁵. As the fluorine atom accepts one electron in its valence shell it becomes anion F⁻. The number of protons is less than electrons therefore effective nuclear charge decreases and the size of the ion increases.

The beakers in the picture above are labeled according to the ionic solutions they contain. What metal or metals could replace copper in the copper(II) nitrate solution?

Answers

Explanation:

When a metal replaces another metal in solution, we say such a reaction has undergone a single displacement reaction.

In such a reaction, metal higher up in the activity series replaces another one due to their position.

To known the metal or metals that will replace the given copper, we need to reference the activity series of metals.

Every metal higher than copper in the series will displace copper from the solution.

So, there metals are: potassium, sodium, lithium, barium, strontium etc.

Consider the following reaction, which occurs at standard state:
2CI(g) -- CI2(g) H= -243.4 kJ
If 15.0g of CI is concerted to chlorine, determine the heat released from this reaction.

Answers

Answer:

The heat energy released from the reaction is approximately 51.4791 kJ

Explanation:

The given parameters are;

The heat of the reaction of 2Cl (g) → Cl₂ (g) = -243.4 J

The given mass of Cl being converted to chlorine gas, Cl₂ = 15.0 g

From the reaction for the heat of formation, we have;

2 moles of chlorine produces 1 mole of Cl₂ to release 243.4 kJ of energy per mole of Cl₂

The mass of 1 mole of Cl ≈ 35.453 g

Therefore, from number of moles, n = Mass/(Molar Mass), we have;

The number of moles of chlorine, in 15.0 g of chlorine = 15.0/35.453 ≈ 0.423 moles

Therefore, given that 2 moles of Cl produces 1 mole of Cl₂, we have;

0.423 moles of Cl will produce 0.423/2 ≈ 0.2115 moles of Cl₂

The heat energy released from the reaction is therefore, H ≈ 0.2115 × 243.4 kJ = 51.4791 kJ.

Which pair best represents a metallic bond?
A. carbon and oxygen two
B. hydrogen atoms two
C. gold atoms
D. sodium and chlorine

Answers

Answer:

C. gold atoms

Explanation:

Metallic bonds are found between atoms of metals. Since gold is the only metal given here, it is the solution to the problem.

Metallic bonds join atoms of metals and alloys together.

The formation of this type of bond is favored by large atomic radius, low ionization energy and a large number of electrons in the valence shell.

The metallic bond is actually an attraction between the positive nuclei of all the closely packed atoms in the lattice and the electron cloud jointly formed by all atoms losing their outermost shell electrons.

Nistu is cooking rice in a pot. When she leaves the pot on the stove for a while, the temperature of the rice increases. What happens to the molecules of the rice when the temperature of the rice increases?

Answers

Answer:

Their average kinetic energy increases

Explanation:

The average kinetic energy of the rice molecules increases as the pot is left on the cooking stove.

Heat is transferred to the pot by conduction from the heat source. The heat is then transferred to the rice in the cooking pot by convection.

As the water in the pot heats up. The rice gains thermal energy. This causes the molecules of the rice particles to start vibrating. As the molecules vibrate about their fixed position, their thermal energy continues to increase.Therefore, the amount of heat absorbed by the rice increases with time and this actually cooks the food.

Answer:

The energy of the molecules in the rice increases.

A compound was analyzed and found to contain the following percent composition: 2.056% hydrogen, 32.69% S, and 65.26% oxygen. Calculate the empirical formula.

Answers

Answer:

H2SO4

Explanation:

Firstly,

2.056% hydrogen = 2.056g of H

32.69% Sulphur = 32.69g of S

65.26% oxygen = 65.26g of O

Next, we convert each mass into moles by dividing by their respective molar mass:

H = 1, S = 32, O = 16

H = 2.056/1 = 2.056mol

S = 32.69/32 = 1.021mol

O = 65.26/16 = 4.078mol

Next, we divide each mole value by the smallest mole value (1.021)

H = 2.056/1.021 = 2.01

S = 1.021/1.021 = 1

O = 4.078/1.021 = 3.99

Approximately the ratio of H to S to O is 2:1:4, hence, the empirical formula for H, S and O is H2SO4.

The empirical formula of a chemical compound is the simplest whole-number ratio of atoms present in a compound

The correct answer of the following is [tex]H_2SO_4[/tex]

The data is given as follows:-

2.056% hydrogen = 2.056g of H 32.69% Sulphur = 32.69g of S65.26% oxygen = 65.26g of O

We have to find the moles in the reaction.

The mas of the element is as follows:-

H = 1S = 32O = 16

After solving the equation we get

[tex]H = \frac{2.056}{1} = 2.056mol\\\\S = \frac{32.69}{32} = 1.021mol\\\\O = \frac{65.26}{16} = 4.078mol[/tex]

Next, we divide each mole value by the smallest mole value (1.021)

[tex]H = \frac{2.056}{1.021} = 2.01\\\\S = \frac{1.021}{1.021} = 1\\\\O = \frac{4.078}{1.021} = 3.99[/tex]

The ratio of H to S to O is 2:1:4,

Hence, the empirical formula for H, S, and O is [tex]H_2SO_4.[/tex]

Calculate the number of sucrose molecules in a 75.0 gram sample.

Answers

Answer:

1.32*10^23 molecules

Explanation:

sucrose formula: C12H22O11

molar mass: 12(12.01)+22(1.01)+11(16.00)=342.34g/mol

75.0 g C12H22O11 * (1 mol C12H22O11)/(342.34g C12H22O11)=0.219 mol C12H22O11

0.219 mol * (6.022*10^23)/mol = 1.32*10^23 molecules (three sig. figures)

The molar mass of sodium is 22.990 g/mol.

The molar mass of chlorine is 35.45 g/mol.

To calculate the molar mass of NaCl, we need to multiply the subscript of each element times its molar mass, then add them together. In this case since there is no subscript, it is understood to be

( 1 × 22.990 g/mol ) + ( 1×35.45 g/mol ) = ?

22.990 g/mol + 35.45 g/mol = ?

58.44 g/mol = ?
