If there were tides on Jupiter, the moon with the greatest influence on the Jupiter tides would be the moon with the greatest mass and closest distance to Jupiter.

Answer:

First, we need to calculate the molarity of the solution:

Molarity = moles of solute / liters of solution

We know the mass of solute (5.00 g) and the volume of solution (20.0 mL = 0.0200 L). To find the moles of solute, we need to divide the mass by the molar mass of NaCl:

moles of NaCl = 5.00 g / 58.44 g/mol = 0.0855 mol

Now we can calculate the molarity:

Molarity = 0.0855 mol / 0.0200 L = 4.28 M

The molarity of the solution is less than the molarity of a saturated NaCl solution at room temperature (5.98 M), so the solution is unsaturated.

Explanation:

C2H4 is the limiting chemical because the ratio of C2H4 to O2 is below the stoichiometric ratio.and the reaction's percent yield is 40.7%.

The limiting reagent or reactant in a chemical process is the one that controls how much product is created. Because elements and compounds respond in an equilibrium chemical formula according to their mole ratios, a limiting reactant is necessary.

C2H4 + O2 CO2 + H2O can be used to calculate the limiting reagent and percent output.

C2H4 has a mass of 170.9 g.

O2 has an overall volume of 52.75 L.

The amount of CO2 generated is 64.1 g.

Calculating the amounts (in moles) of each reactant and comparing them to the stoichiometric ratio in the balanced solution will help us identify the limiting reagent.

The molecular mass of C2H4 can be used to determine how much is present:

17.9 g C2H4 divided by (2 x 12.01 g/mol + 4 x 1.01 g/mol) results in 3.58 mol C2H4.

The ideal law of gases can be used to determine the quantity of O2:

PV/RT equals (1 atm)(52.75 L)/(0.0821 L atm/mol K)(298 K) = 2.16 mol O2 for n(O2).

Then, C2H4:O2 = 3.58 mol; 2.16 mol; 1.66 mol; 1

C2H4 to O2 stoichiometric ratio is 1 to 3.

C2H4 is the limiting reactant because the ratio of C2H4 to O2 is lower than the stoichiometric ratio. This implies that the O2 will exhaust itself completely before the C2H4 does as well.

We can use the mole fraction of C2H4 to CO2 in the balanced equation to calculate the potential yield of CO2:

1 mol C2H4 results in 1 mol CO2.

Theoretically, 3.58 mol C2H4 1 mol CO2/1 mol C2H4 44.01 g/mol = 157.3 g CO2 is the output of CO2.

To determine the percent yield, multiply the result by 100% after dividing the real yield by the theoretical yield:

(Actual yield / Theoretical yield) / 100% = Percent return

The amount of CO2 that actually occurred is 64.1 g. The percent yield is therefore: Percent yield = (64.1 g/157.3 g) 100% = 40.7%

As a result, C2H4 serves as the limiting reactant, and the reaction's percent yield is 40.7%.

The strength of the ionic bond is directly dependent upon the quantity of the charges and inversely dependent on the distance between the charged particles. A cation with a 2+ charge will make a stronger ionic bond than a cation with a 1+ charge.

The amount of electrons an atom gains or loses when it forms an ion determines the strength of the ionic charge. An atom becomes positively charged when an electron is lost, and negatively charged when an electron is gained.

The ionic charge increases with the amount of electrons lost or acquired. An ion that has lost two electrons, for instance, will have a higher positive charge than one that has lost only one. Similar to this, an ion with three electrons obtained will have a higher negative charge than one with only one.

The total mass of the reactants equals total mass of the products, means there is no change in mass during a chemical reaction.

This is due to the law of conservation of mass, which states that the total mass of a system does not change regardless of variations in its components. For mass cannot be created or destroyed, rearranged, or only moved.

In chemical reaction, atoms has rearranged itself to form a new molecules, but the total mass remains the same. It is because the total mass of reactants and products is sum of masses of each atom involved.

So, in any chemical reaction, the total mass of reactants and products remains the same because mass is conserved.

The reagent which is completely consumed in a reaction and thereby limits how much product can be formed is called the limiting reagent. Here the limiting reagent is O₂.

The quantity of the product which is actually made compared with the maximum calculated yield is defined as the percent yield. The percent yield is the ratio of the actual yield to the theoretical yield.

% Yield = Actual yield / Theoretical yield × 100

The number of moles (n) = Given mass / Molar mass

'n' of C₂H₄ = 170.9 / 28.05 = 6.09 mol

'n' of O₂ = 64.1 / 31.9 = 1.65 mol

So O₂ is the limiting reactant.

Theoretical yield of CO₂ is:

170.9 × 1 mol / 28 g × 2 mol / 1 × 44/1 = 537.1 g CO₂

%Yield = 64.1 / 537.1 × 100 = 11.93 %

The dry hydrogen gas would occupy 0.152 L at 1 atm and 298 K when solving with the combined gas equation.

It is a mathematical expression that states the relationship between the pressure, volume, and temperature.

The gas equation can be stated as:

                                           (P₁V₁)/T₁ = (P₂V₂)/T₂

To solve this problem, we need to use the combined gas law:

We are given the initial pressure (707.3 Torr), but we need to calculate the initial volume and temperature of the hydrogen gas.

P_total = P_H₂ + P_H₂O

where P_H₂ is the pressure of the hydrogen gas and P_H₂O is the vapor pressure of water at 10 °C (9.21 Torr).

P_total = 707.3 Torr

P_H₂O = 9.21 Torr

So, P_H₂ = P_total - P_H₂O = 698.09 Torr

Converting the volume of hydrogen gas collected to the volume at standard temperature and pressure (STP) using the following equation:

V₂ = V₁(P₁/P₂)(T₂/T₁)

Solving for V₁ by rearranging the equation:

V₁ = V₂(P₂/P₁)(T₁/T₂)

Converting the volume of hydrogen gas collected to liters:

V₂ = 125 mL = 0.125 L

Next, we can putting in the values we know:

P₁ = 698.09 Torr

P₂ = 1 atm = 760 Torr

T₂ = 298 K

We can solve for T₁ by using the ideal gas law:

PV = nRT

T = PV/nR

Calculating the number of moles of hydrogen:

n = m/M

n = 0.4 g / 65.38 g/mol = 0.006118 mol

Now we can put in the values we know into the ideal gas law:

T₁ = (P₁V₁)/(nR)

= (698.09 Torr)(0.125 L)/(0.006118 mol)(0.08206 L·atm/mol·K)

= 343.2 K

Finally, we can solve for V₁:

V₁ = V₂(P₂/P₁)(T₁/T₂)

= (0.125 L)(760 Torr/698.09 Torr)(343.2 K/298 K) = 0.152 L

Therefore, the dry hydrogen gas would occupy 0.152 L at 1 atm and 298 K.

Answer:

To determine the formula mass of the gas, we can use the ideal gas law:

PV = nRT

where P is the pressure of the gas, V is the volume of the container, n is the number of moles of gas, R is the ideal gas constant, and T is the temperature of the gas in Kelvin.

First, we need to convert the given temperature of 27°C to Kelvin:

T = 27°C + 273.15 = 300.15 K

Next, we can rearrange the ideal gas law to solve for the number of moles of gas:

n = PV/RT

where P = 300.0 kPa, V = 25.0 L, R = 8.31 J/(mol·K), and T = 300.15 K.

n = (300.0 kPa)(25.0 L)/(8.31 J/(mol·K) x 300.15 K) ≈ 30.12 mol

Now, we can calculate the molar mass (formula mass) of the gas using its mass and the number of moles:

molar mass = mass / number of moles

where the mass is given as 96.0 g.

molar mass = 96.0 g / 30.12 mol ≈ 3.19 g/mol

Therefore, the formula mass of the gas is approximately 3.19 g/mol.

0.5 moles of NH3 will form from the complete reaction of 14.0 g of N2.

Mole is a unit of measurement used to measure the amount of a substance. It is defined as the number of atoms, molecules, ions, or other particles present in a given sample of a substance. The mole is an important concept in chemistry because it allows for direct comparison of the relative amounts of substances in a reaction. It is also used in physics to calculate the number of particles in a given volume. The mole is a base unit in the International System of Units (SI), and its symbol is "mol".

The number of moles of NH3 produced from 14.0 g of N2 can be determined using the following equation:
moles NH3 = (14.0 g N2) / (28.0 g/mol N2) x (1 mol NH3 / 3 mol H2)
moles NH3 = 0.5 mol NH3
Therefore, 0.5 moles of NH3 will form from the complete reaction of 14.0 g of N2.
