Therefore, the name of noble gas is Radon.

Answer:

The limiting reagent is CuCl

Explanation:

The initial number of moles of aluminum, Al = 4.5 moles

The number of moles of copper, Cu = 6.5 moles

The given chemical reaction is presented as follows;

2Al + 3CuCl → 2AlCl₃ + 3Cu

Therefore, we have, 2 moles of aluminum combine with 3 moles of CuCl produces 2 moles of AlCl₃ and 3 moles of Cu

1 mole of Al will combine with (3/2) moles of CuCl,

Therefore, 4.5 moles of Al will combine with (4.5 × (3/2) = 6.75) 6.75 moles of CuCl

Given that the number of moles of CuCl present is only 6.5 moles which is less than the 6.75 moles required to combine with the 4.5 moles, the 6.5 moles of CuCl limits the amount of AlCl₃ and Cu produced, and therefore the CuCl is the limiting reagent.

Answer:

C

Explanation:

C. Adding a catalyst would increase the reaction rate.

A catalyst is a substance that increases the rate of a chemical reaction by lowering the activation energy required for the reaction to occur.

A catalyst enhances the probability of successful collisions between reactant molecules, which raises the pace of the reaction by offering an additional avenue for the reaction to occur.

As there would be fewer reactant molecules accessible to react with one another, decreasing reactant concentrations would result in a slower pace of reaction.

Due to the fact that chemical reactions often require energy to take place, eliminating heat from the system would also slow down the reaction rate. A lower value for k would result in a lower rate constant, which would lower the response rate.

Answer:

Pertaining to the interrogate, the answer to such is acknowledged and henceforth disseminated as 43.0%

Explanation:

To evaluate such, the following must be comprehended:

Percent Yield Calculator:

% Yield = (What You Actually Got / What You Should Theoretically Get) * 100

The following variables may be denoted, as stated within the interrogate:

Yielded/Produced: 6 grams.

Theoretical Yield: 14 grams.

(6 g/14 g) * 100 = 42.8571428571

*Grams measurement cancels*

42.8 ==> 43.0%

Thus, if rounded to the nearest tenth, the percent yield is equivalent to 43.0%.

Answer:

Trial Y, because the volume of product per unit time is lower than Trial X

Explanation:

In the chemistry experimental setup, the amount of gaseous product formed by the different concentration of the trials are measured and the result is plotted on a graph

The given graph, shows;

The vertical, y-axis = The amount of product

The horizontal, x-axis = Th time of the reaction

Trial X = The graph line with a steeper slope

Trial Y = The graph line

Increase in the concentration f the reactants, increases the number of collisions, and therefore, the number of effective collisions that gives the product also increases, and the overall rate of reaction increases

A more concentrated reactants produce more product in a shorter time (yield more product in less time) than a less concentrated one, and a more concentrated reactant would have a steeper slope and therefore produce more volume of the product in less time than a less concentrated reactant, which produces a lower volume in the same time

Therefore, the trial that has a lower concentration of the reactant is Trial Y, because the volume of product per unit time is lower than Trial X.

Answer:

No, it is not feasible because the Gibbs free energy change is positive

Explanation:

∆Hreaction= (-602 KJ/mol) - (-348 KJ/mol) = -254 KJ/mol

∆Sreaction = (42 + 27) J/Kmol - (33 + 44) J/K = -8J/Kmol

From;

∆G = ∆H - T∆S

∆G = 254 × 10^3 J/mol - [340K × (-8 J/Kmol)]

∆G = 2.57 × 10^5 J/mol

Note that when the change in free energy is positive, a reaction is non spontaneous. Only a reaction that has a negative change in free energy is spontaneous.

Answer:

B. Yes, it is feasible because the Gibbs free energy change is negative.

Isotopes are atoms of the same element that have different masses. The relative atomic mass (am) is a weighted average that takes into account the abundance of each isotope. We can calculate the relative atomic mass using the following expression.

[tex]am = \frac{\Sigma m_i \times ab_i}{100}[/tex]

where,

For Gallium,

[tex]70.59 amu = \frac{69 amu\ x + 71 amu\ y}{100}[/tex]     [1]

where "x" and "y" are the unknown abundances.

We also know that the sum of both abundances must be 100%.

x + y = 100

y = 100 - x   [2]

If we replace [2] in [1], we get

[tex]70.59 amu = \frac{69 amu\ x + 71 amu\ (100-x)}{100} \\7059 amu = -2 amu\ x + 7100amu \\x = 20.5[/tex]

Then, in [2]

y = 100 - x = 100 - 20.5 = 79.5

In conclusion, Ga-69 has an abundance of 20.5% and Ga-71 has an abundance of 79.5%.
