Answers

4365 that’s what the answer is

Final answer:

The reaction will proceed in the forward direction to reach equilibrium.

Explanation:

To determine which reaction will go in order to reach equilibrium, we need to compare the initial number of moles of reactants to the stoichiometric coefficients of the balanced equation. The balanced equation for the reaction between NH₃, N₂, and H₂ is:

NH₃ + N₂ ↔ 2NH₃

Since the initial number of moles of NH₃, N₂, and H₂ are the same (1.00 mole each), the reaction will proceed in the forward direction to reach equilibrium.

A solution contains 15 g Na₂CO₃ and 235 g if H₂O? What is the mass% of the solution?

Answers

The total mass of the solution is 15 g (Na₂CO₃) + 235 g (H₂O) = 250 g (solution).

Now, let's calculate the mass percent of Na₂CO₃:
Mass percent of Na₂CO₃ = (mass of Na₂CO₃ / total mass of solution) * 100
= (15 g / 250 g) * 100
= 6%

Therefore, the mass percent of Na₂CO₃ in the solution is 6%.

Final answer:

The mass percent of a solution is calculated by dividing the mass of the solute by the total mass of the solution and multiplying by 100%. In this case, the solute is Na₂CO₃ and the solvent is H₂O. The calculation yields a mass percent of 6% for Na₂CO₃ in the solution.

Explanation:

To calculate the mass percent of a solution, we need the mass of the solute and the mass of the solution (which is the sum of the masses of the solute and the solvent). In your given solution, you have 15 g of Na₂CO₃ (solute) and 235 g of H₂O (solvent). Therefore, the total mass of the solution is 15 g (Na₂CO₃) + 235 g (H₂O) = 250 g.

Now, to find the mass percent of Na₂CO₃ in the solution, we use the following formula:

Mass percent = (mass of solute / total mass of solution) × 100%

Substitute the known values into the formula, we get:

Mass percent = (15 g / 250 g) × 100% = 6%

So, the mass percentage of Na₂CO₃ in the H₂O solution is 6%.

Which substance is an electrolyte?
(1) CH3OH (3) H2O
(2) C6H12O6 (4) KOH

Answers

Answer:

The answer is 4) KOH

Explanation:

Electrolytes are substances which ionize when dissolved in water. They are classified as:

Strong electrolyte: Which completely ionize when in water. Eg: NAOH, KOH (produces K+ and OH- ions when dissolved in water)

Weak electrolyte: partially ionize when in water. Eg: Acetic acid

Non-electrolyte: Do not ionize at all in water. Eg: Alcohols such CH3OH, sugars such as glucose (C6H12O6).

KOH is an electrolyte. Therefore, option (4) is correct.

Electricity flows via water-dissolved materials. Ions in a solution conduct electricity.The options:When dissolved in water, methanol (CH3OH) does not form ions.2. C6H12O6 (Glucose): It does not dissolve into ions in water, hence it is not an electrolyte.

Water doesn't dissolve into ions, hence it's not an electrolyte.4. Dissolved in water, potassium hydroxide (KOH) forms ions (K+ and OH-), making it an electrolyte. Therefore, KOH as an electrolyte is the correct option.

What does the number 84 in the name krypton-84 represent?b. Atomic number
c. Mass number
d. Twice the number of protons

Answers

The number 84 in the name krypton-84 represent its mass number.

What is Mass number?

The total number of neutrons and protons in an atom are calculated to determine the mass number.

The smallest component of an element, an atom, combines with other atoms to form molecules, which make up the majority of the universe's things.

The total number of protons and neutrons in an atom's nucleus is known as the mass number in nuclear physics. The mass number is frequently used to distinguish between an element's isotopes.

A specific element can only be created from one type of atom, e.g., diamond can only be created from carbon atoms and gold can only be created from gold atoms. Protons, neutrons, and electrons make up the atoms.

Therefore, The number 84 in the name krypton-84 represent its mass number.

__________ refers to the total energy of a system.

Answers

The internal energy refers to the total energy of a system. The enrgies are kinetic energy and potential energy of the system that makes up the whole energies of the system.

Enthalpy refers to the total energy of a system. Enthalpy is basically a thermodynamic unit of measurement that determines the total heat content of a system. This means that all energy is included in the measurement - the energy used to make the system, the energy of the system, and the energy it uses to keep the environment separate from the system.

Which of the following combinations will result in a reaction that is spontaneous at all temperatures?positive enthalpy change and positive entropy change
positive enthalpy change and negative entropy change
negative enthalpy change and positive entropy change
negative enthalpy change and negative entropy change

Answers

The right answer for the question that is being asked and shown above is that: "negative enthalpy change and negative entropy change." The combination that will result in a reaction that is spontaneous at all temperatures is negative enthalpy change and negative entropy change

Answer:

Spontaneous at ALL Temperatures: Negative enthalpy change and positive entropy change
