The given electronic configuration 1s²2s²2p⁶3s²3p⁶4s²3d⁸ is the Nickel (Ni). Therefore, option (B) is correct.

The electron configuration can be explained as electrons being filled in different energy levels of an atom of a particular element. In the electron configuration, the number of electrons is usually written as a superscript of atomic subshells. For example, the electron configuration of Oxygen is written as 1s²2s²2p⁴.

The sequence of fully filled subshells that correspond to the electronic configuration of a noble gas is denoted by square brackets. The principal quantum number (n) can be used to evaluate the maximum number of electrons in an electron shell.

The value of 2n² is given the maximum number of electrons. The atomic orbitals at low energy must be filled first occupying an orbital with a higher energy level.

The total number of electrons filled in the given electronic configuration  1s²2s²2p⁶3s²3p⁶4s²3d⁸  is 28. The atomic number of Nickel is 28 therefore it is the configuration of Nickel.

Explanation:

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

Therefore,

2p < 3s   True

3d < 4p   True

3d < 4s     False

There are 500 mg of calcium carbonate is in this caltrate tablet

The equation of the reaction is;

2HCl(aq) + CaCO3(aq) ------> CaCl2(aq) + CO2(g) + H2O(l)

Next, we have to obtain the amount HCl reacted as follows;

Number of moles = concentration × volume

Volume = 34.46 mL or 0.03446 L

Concentration =  0.291 M

Number of moles = 0.291 M ×  0.03446 L

Number of moles = 0.01 moles

Since the reaction of HCl and CaCO3 are in the ratio of 2:1

2 moles of HCl reacts with 1 mole of CaCO3

0.01 moles of HCl reacts with  0.01 moles ×  1 mole/2 moles

= 0.005 moles of CaCO3

Mass of CaCO3 = number of moles  × molar mass

Mass of CaCO3 =  0.005 moles of CaCO3 × 100 g/mol

Mass of CaCO3 =  0.5 g or 500 mg

Answer:

About 10.2 g Li₃N.

Explanation:

We are given the reaction:

[tex]\displaystyle \text{6 Li(s) + N$_2$(g) }\longrightarrow \text{2 Li$_3$N(s)}[/tex]

And we want to determine the amount of Li₃N that can be formed from 6.07 g of Li and an excess of nitrogen.

To convert from g Li to g Li₃N, we can: (1) convert from g Li to mol Li, (2) mol Li to mol Li₃N, and (3) mol Li₃N to g Li₃N.

Molecular weight of Li₃N:

[tex]\displaystyle \begin{aligned}\text{MW}_\text{Li$_3$N} & = (3 (6.94) + 14.01) \text{ g/mol} \\ \\ & =34.83\text{ g/mol} \end{aligned}[/tex]

This yields three ratios:

[tex]\displaystyle \frac{1 \text{ mol Li}}{6.94 \text{ g Li}}, \frac{2 \text{ mol Li$_3$N}}{6 \text{ mol Li}}, \text{ and } \frac{34.83 \text{ g Li$_3$N}}{1 \text{ mol Li$_3$N}}[/tex]

From the initial value, multiply:

[tex]\displaystyle 6.07 \text{ g Li} \cdot \frac{ 1 \text{ mol Li}}{6.94 \text{ g Li}} \cdot \frac{2 \text{ mol Li$_3$N}}{6 \text{ mol Li}} \cdot \frac{34.83 \text{ g Li$_3$N}}{1 \text{ mol Li$_3$N}} = 10.2\text{ g Li$_3$N}[/tex]

In conclusion, 10.2 g of Li₃N is formed from 6.07 g of Li and an excess of nitrogen.

The formula and names of the compounds are:

1. Formula of compound => MoF₃

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:

To convert 100.0 g of water at 20.0 °C to steam at 100.0 °C requires 259.5 kJ of energy.

The amount of heat which is required for a phase change of a substance without any change in temperature is known as latent heat. Here the amount of heat required is 10,800 calories.

The heat capacity of a substance or a system is defined as the amount of heat required to raise its temperature through 1°C. It is denoted by C. The specific heat capacity is the amount of heat required to raise the temperature of 1 gram of the substance through 1°C.

The equation to calculate the heat required is:

Q = mc (T₂ - T₁) + mL₁

L = Latent heat of vaporization of water

m = mass

c = specific heat capacity

T₂ = Final temperature

T₁ = Initial temperature

T₂ - T₁ = 100 - 100 = 0°C

Q = 20 g × 1 cal /g°C × 0°C +  20 g × 540 cal/g

Q = 10,800 calories

Thus the amount of heat required is 10,800 calories.
