Which statement best describes how electrons fill orbitals in the periodic table?

Answers

Answer 1
Answer: The arrangement of the periodic table is related to the electron configuration of the atoms of each element. Electron configurations represents how electrons are distributed. For instance, the neon atom has the electron configuration of 1s^2 2s^2 2p^6.

Calculate the mass percent of hydrogen in diethyl ether. Round your answer to the nearest percentage.

Answers

Diethyl ether has a molecular formula of C4H10O, which means it contains 2 hydrogen atoms per molecule.

To calculate the mass percent of hydrogen in diethyl ether, we need to know the molar mass of hydrogen and the molar mass of diethyl ether. The molar mass of hydrogen is approximately 1 g/mol, while the molar mass of diethyl ether is approximately 74 g/mol.

The mass percent of hydrogen can be calculated using the following formula:
mass percent of hydrogen = (mass of hydrogen / total mass of compound) x 100%

Substituting the values for diethyl ether, we get:
mass percent of hydrogen = (2 x 1 g/mol / 74 g/mol) x 100% = 2.7%

Therefore, the mass percent of hydrogen in diethyl ether is approximately 2.7%.

Final answer:

The mass percent of hydrogen in diethyl ether is 1.36%.

Explanation:

To calculate the mass percent of hydrogen in diethyl ether, we need to determine the mass of hydrogen in the compound and divide it by the total mass of diethyl ether. The formula of diethyl ether is C4H10O, so the molar mass is 74.12 g/mol. The molar mass of hydrogen is 1.008 g/mol.

Mass percent of hydrogen = (mass of hydrogen / mass of diethyl ether) × 100%

Mass percent of hydrogen = (1.008 g/mol / 74.12 g/mol) × 100% = 1.36%

8 Which quantity is equal to one mole of Au?(1) the atomic mass in grams(2) the atomic number in grams
(3) the mass of neutrons in grams
(4) the number of neutrons in grams

Answers

Answer is (1) the atomic mass in grams since One mole of any element is equal to the atomic mass in grams.

Answer: option (1) the atomic mass in grams.

Explanation:

1) The atomic mass is the mass in grams of one mole of atoms.

2) Hence, it is always the atomic mass of an element equal to the mass of one mole of atoms of such element. Therefore, the atomic mass of Au is the mass of one moles of atoms of Au.

3) Here are some examples:

i) Atomic mass of gold: 196.67 g/atoms, means that 196.97 grams of Au is one mole of Au.

ii) Atomic mass of hydrogen: 1.008 g/mol, means that 1.008 grams of H is one mole of H.

iii) Atomic mass of oxygen: 15.999 g/mol, means that 15.999 grams of O is one mole of O.

iv) Atomic mass of lead: 207.2 g/mol, means that 207.2 grams of Pb is one mole of Pb.

Now you see it, the atomic mass in grams of an element is equal to one mole of the element.

Which of the following will result in a chemical change? A. Burning coal in a furnace
B. Drying wood in a shed
C. Melting ice to obtain water
D. Evaporating alcohol into vapor

Answers

Coal combustion causes a chemical change. Burning coal in a furnace  will result in a chemical change. Therefore, option A is correct.

What is chemical change ?

A chemical change is the transformation of one material into another, the formation of new materials with different properties, and the formation of one or more new substances. It occurs when one substance reacts with another to form a new substance.

Coal combustion causes a chemical change. The main component, carbon, is converted to carbon dioxide when coal is burned. This process is irreversible.

When carbon is burned, it produces carbon dioxide, and hydrogen produces water. Each of these reactions generates a different amount of heat. Because this process cannot be reversed, coal combustion is a chemical change.

Thus, option A is correct.

Which type of reaction occurs when nonmetal atoms become negative nonmetal ions?A. oxidation
B. reduction
C. substitution
D. condensation

Answers

Answer: Option (B) is the correct answer.

Explanation:

When an atom gains electrons then it becomes rich in electrons and therefore it acquires a negative charge.

Also, it is known that a reduction reaction is a reaction in which an element gain electron(s).

For example, Br_(2) + 2e^(-) \rightarrow 2Br^(-) is a reduction reaction.

Thus, we can conclude that when nonmetal atoms become negative nonmetal ions then type of reaction which occurs is reduction reaction.

The answer is B. reduction. The atom becoming negative ions means it gains electrons. The reaction which gain electrons is reduction reaction. So the answer is B.
