Answer:

b

Explanation:

The concept Arrhenius equation is used here to determine the temperature dependence of the rate of a reaction. An increase in temperature increases the rate of a reaction. The correct option is B.

The rate of a chemical reaction is affected by the factors like temperature and activation energy. The influence of these factors on the rate of the reaction is explained by the Arrhenius equation.

The equation is given as:

[tex]k = A. e^{-} ^{E_{a} } /RT[/tex]

k - Rate constant

A - Frequency factor

Eₐ - Activation energy

R - Gas constant

T - Temperature

Since 'Temperature' appears in the denominator of the negative power of the exponential factor of the equation, it is evident that an increase in temperature increases the value of rate constant and thereby increases the rate of the reaction.

Thus the correct option is B.

Name of compound => Molybdenum trifluoride

2. Formula of compound => MoF₄

Name of compound => Molybdenum tetrafluoride

3. Formula of compound => MoF₅

Name of compound => Molybdenum pentafluoride  

4. Formula of compound => MoF₆

Name of compound => Molybdenum hexafluoride  

1. Determination of the name and formula of the molybdenum fluoride having 63.0% of molybdenum.

Molybdenum (Mo) = 63.0%

Fluorine (F) = 100 – 63 = 37%

Mo = 63.0%

F = 37%

Divide by their molar mass

Mo = 63.0 / 96 = 0.656

F = 37 / 19 = 1.947

Divide by the smallest

Mo = 0.656 / 0.656 = 1

F = 1.947 / 0.656 = 3

Therefore,

Formula of compound => MoF₃

Name of compound => Molybdenum trifluoride

2. Determination of the name and formula of the molybdenum fluoride having 56.0% of molybdenum.

Molybdenum (Mo) = 56.0%,

Fluorine (F) = 100 – 56 = 44%

Mo = 56%

F = 44%

Divide by their molar mass

Mo = 56 / 96 = 0.583

F = 44 / 19 = 2.316

Divide by the smallest

Mo = 0.583 / 0.583 = 1

F = 2.316 / 0.583 = 4

Therefore,

Formula of compound => MoF₄

Name of compound => Molybdenum tetrafluoride

3. Determination of the name and formula of the molybdenum fluoride having 50.0% of molybdenum.

Molybdenum (Mo) = 50.0%,

Fluorine (F) = 100 – 50 = 50%

Mo = 50%

F = 50%

Divide by their molar mass

Mo = 50 / 96 = 0.520

F = 50 / 19 = 2.632

Divide by the smallest

Mo = 0.520 / 0.520 = 1

F = 2.632 / 0.520 = 5

Therefore,

Formula of compound => MoF₅

Name of compound => Molybdenum pentafluoride  

4. Determination of the name and formula of the molybdenum fluoride having 46.0% of molybdenum.

Molybdenum (Mo) = 46.0%,

Fluorine (F) = 100 – 46 = 54%

Mo = 46%

F = 54%

Divide by their molar mass

Mo = 46 / 96 = 0.479

F = 54 / 19 = 2.842

Divide by the smallest

Mo = 0.479 / 0.479 = 1

F = 2.842 / 0.479 = 6

Therefore,

Formula of compound => MoF₆

Name of compound => Molybdenum hexafluoride

Answer:  See below

Explanation:  a.  The mass of an element is composed of:

protons:     1 amu each

neutrons:   1 amu each

electrons:   0 amu each

Only the protons and neutrons are counted in the atomic mass of an element

b.  Electrons are assigned a mass of 0.  They do have a mass, but it is exceedingly small compared to the protons and neutrons, so they are left out of the calculation of an element's mass.

c.  An element becomes unstable if the neutrons exceed the protons by a certain ratio, dependent on the element.

The half life time period of decaying 96 atom sample to 3 atoms of Fermium-253 if it has a half-life of 0.334 seconds is 1.67 s.

Half life time period is defined as the time interval which is required to decay the substance into half of its concentration. It is denoted by t(1/2).

As, atom decay in first half life time = 48 atoms.

Atom decay in second half life time = 24 atoms.

Atom decay in third half life time = 12 atoms.

Atom decay in fourth half life time = 6 atoms.

Atom decay in fifth half life time = 3 atoms.

So, we can see that in 5 half life time 96 atoms decay into 3 atoms.

So, time interval require to decay 96 atoms into 3 atoms is 5 × 0.334 = 1.67 s.

Thus, we concluded that the half life time period of decaying 96 atom sample to 3 atoms of Fermium-253 if it has a half-life of 0.334 seconds is 1.67 s.

3d < 4s  is NOT a correct ordering of subshells in the periodic table because 4s is at a lower energy level than 3d.

According to the Aufbau principle,   The electron configuration of an element tells how electrons of that element are arranged in thier subshells from their lowest energy state before the highest energy state.

For example, before a 2s subshell can be occupied, A 1s subshell must be filled.

The orbitals are filled in this order:

1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s,

For example, Na (sodium) with 11 atomic number is written as 1s2 2s2 2p6 3s1

There are 2.72 kilograms of nitrogen present in a 3.50 L sample of N₂O.

To find the mass of nitrogen in N₂O, we must calculate the number of moles of N₂O.  

[tex] n_{N_{2}O} = \frac{m_{N_{2}O}}{M{N_{2}O}} [/tex]  (1)

Where:

[tex] m_{N_{2}O}[/tex]: is the mass of N₂O

[tex]M_{N_{2}O}[/tex]: is the molar mass of N₂O = 44.013 g/mol

The mass of N₂O can be founded from the density:

[tex] d = \frac{m}{V} [/tex] (2)

Where:

d: is the density of N₂O = 1.22 g/mL

V: is the volume = 3.50 L = 3500 mL

Then, the mass of N₂O is (eq 2):

[tex] m = d*V = 1.22 g/mL*3500 mL = 4270 g [/tex]

Now, the number of moles of N₂O is (eq 1):

[tex] n_{N_{2}O} = \frac{4270 g}{44.013 g/mol} = 97.02 \:moles [/tex]

Knowing that in 1 mol of N₂O we have 2 moles of N, the number of moles of nitrogen is:

[tex] n_{N} = \frac{2\: moles \: N}{1 \:mol \: N_{2}O}*n_{N_{2}O} = \frac{2\: moles \: N}{1 \:mol \: N_{2}O}*97.02 \:moles \:N_{2}O = 194.04 \: moles [/tex]

Finally, with the number of moles of N we can find its mass:

[tex] m = n_{N}*M_{N} = 194.04 \:moles*14.007 g/mol = 2717.9 g = 2.72 kg [/tex]

Therefore, there are 2.72 kilograms of nitrogen.
