Answer:

56.67 g of NH₃.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

N₂ + 3H₂ —> 2NH₃

Next, we shall determine the masses of N₂ and H₂ that reacted and the mass of NH₃ produced from the balanced equation. This is illustrated below:

Molar mass of N₂ = 14 × 2 = 28 g/mol

Mass of N₂ from the balanced equation = 1 × 28 = 28 g

Molar mass of H₂ = 1 × 2 = 2 g/mol

Mass of H₂ from the balanced equation = 3 × 2 = 6 g

Molar mass of NH₃ = 14 + (3×1) = 14 + 3 = 17 g/mol

Mass of NH₃ from the balanced equation = 2 × 17 = 34 g

SUMMARY:

From the balanced equation above,

28 g of N₂ reacted with 6 g of H₂ to produce 34 g of NH₃

Next, we shall determine the limiting reactant. This can be obtained as follow:

From the balanced equation above,

28 g of N₂ reacted with 6 g of H₂.

Therefore, 80 g of N₂ will react with = (80 × 6)/28 = 17.14 g of H₂.

We can see from the calculation made above that a higher mass (i.e 17.14 g) of H₂ than what was given (i.e 10 g) is required to react completely with 80 g of N₂. Thus, H₂ is the limiting reactant and N₂ is the excess reactant.

Finally, we shall determine the maximum mass of ammonia (NH₃) produced from the reaction.

To obtain the maximum mass of NH₃, the limiting reactant will be used because all of it is consumed in the reaction.

The limiting reactant is H₂ and the maximum mass of NH₃ can be obtained as follow:

From the balanced equation above,

6 g of H₂ reacted to produce 34 g of NH₃.

Therefore, 10 g of H₂ will react to produce = (10 × 34)/6 = 56.67 g of NH₃.

Therefore, 56.67 g of NH₃ is produced from the reaction.

Answer:

This question appear incomplete

Explanation:

This question appear incomplete because of the absence of the value of the count of the ions inside the unit cell. To determine the mass (in grams) of LiCl in a unit cell, the formula below can be used

count of ions inside the unit cell = mass of LiCl ÷ molar mass of LiCl

Hence,

Mass of LiCl = count of ions inside the unit cell × molar mass of LiCl

Count of ions (Li⁺ and Cl⁻ ions specifically) inside the unit cell should have been provided in the question

Molar mass of LiCl was given to be 42.39 g/mol

The mass of the LiCl unit cell has been 2.82 [tex]\rm \bold{\times\;e^-^2^2}[/tex] grams.

The given structure has been the unit cell of the LiCl having 4 atoms of Li and 4 atoms of Cl.

The number of Li and Cl in a molecule of LiCl has been 1, and 1 respectively.

The presence of 4 atoms of Li and Cl indicates that there has been the presence of 4 molecules of LiCl.

The molar mass ofLiCl = 42.39 g/mol.

The number of molecules present in a mole of the sample has been equivalent to the Avagadro number.

6.023 [tex]\rm \times\;10^2^3[/tex] molecules = 1 mole LiCl.

6.023 [tex]\rm \times\;10^2^3[/tex] molecules = 42.39 grams LiCl.

The mass of 4 molecules of LiCl has been:

4 molecules = [tex]\rm \dfrac{42.39}{6.023\;\times\;1^2^3}\;\times\;4[/tex]

4 molecules = 2.82 [tex]\rm \times\;10^-^2^2[/tex] grams

2.82 [tex]\rm \times\;10^-^2^2[/tex] grams =  2.82 [tex]\rm \bold{\times\;e^-^2^2}[/tex] grams.

The mass of the LiCl unit cell has been 2.82 [tex]\rm \bold{\times\;e^-^2^2}[/tex] grams.

Answer:

The balanced reactions are:

C₂ + 2B → B₂C₂

Ag₄ + 2SO₂ → 4AgO + S₂

Explanation:

The Law of Conservation of Matter postulates that "the mass is not created or destroyed, only transformed." This means that the reagents interact with each other and form new products with physical and chemical properties different from those of the reagents because the atoms of the substances are ordered differently. But the amount of matter or mass before and after a transformation (chemical reaction) is always the same, that is, the quantities of the masses involved in a given reaction must be constant at all times, not changing in their proportions when the reaction ends. In other words, then the mass before the chemical reaction is equal to the mass after the reaction.

In other words, the law of conservation of matter states that since no atom can be created or destroyed in a chemical reaction, the number of atoms that are present in the reagents has to be equal to the number of atoms present in the products.

Then, you must balance the chemical equation. For that, you must first look at the subscripts next to each atom to find the number of atoms in the equation. If the same atom appears in more than one molecule, you must add its amounts .

The coefficients located in front of each molecule indicate the amount of each molecule for the reaction. This coefficient can be modified to balance the equation, just as you should never alter the subscripts.

By multiplying the coefficient mentioned by the subscript, you get the amount of each element present in the reaction.  

You have:

C₂ + B → B₂C₂

Left side: 2 C and 1 B.

Right side: 2 C and 2 B.

Carbon C is balanced since you have the same amount of the element on each side of the reaction, but boron B is not balanced. So, balancing the reaction:

C₂ + 2B → B₂C₂

Left side: 2 C and 2 B.

Right side: 2 C and 2 B.

Now you have the same amount of each element on each side of the reaction, so the reaction is balanced.

Now you have:

Ag₄ + SO₂ → AgO + S₂

Left side: 4 Ag, 1 S and 2 O.

Right side: 1 Ag, 2 S and 1 O.

Balancing the Ag:

Ag₄ + SO₂ → 4AgO + S₂

Left side: 4 Ag, 1 S and 2 O.

Right side: 4 Ag, 2 S and 4 O.

Balancing the O:

Ag₄ + 2SO₂ → 4AgO + S₂

Left side: 4 Ag, 2 S and 4 O.

Right side: 4 Ag, 2 S and 4 O.

You have the same amount of each element on each side of the reaction, so the reaction is balanced.

Answer:

The relative atomic mass of X is 183.4

Explanation:

The relative atomic mass of an element is the weighted average of the masses of the isotopes using the carbon-12 atom has a mass of exactly 12 units as as a standard.

The relative sizes of the peaks gives a direct measure of the relative abundances of the isotopes. The tallest peak is often given an arbitrary height of 100 and is known as the base peak.

To calculate the relative atomic mass of the element X which has 3 stable isotopes with the relative peak intensities as given below:

79.52 for 180.0 u, 100.0 for 184.0 u, and 82.98 for 186.0 u, the sum of the products of the relative peak intensity of each isotope and their isotopic mass is divided by the sum of the peak intensities.

Relative atomic mass of X = (79.52 × 180) + (100 × 184.0) + (82.98 × 186)/(79.52 + 100 + 82.98)

Relative atomic mass of X = (14313.6 + 18400 + 15434.28)/(262.5)

Relative atomic mass of X = 48147.88/262.5 = 183.4

Therefore, the relative atomic mass of X is 183.4

The average atomic mass of element X has been 183.42 amu.

The average atomic mass of the element has been given with the abundance and the atomic mass of the isotopes present.

The average atomic mass (amu) has been given as:

[tex]amu=\dfrac{(am\;\times\; \rm \% abundance)_1\;+\;(\textit am\;\times\;\% abundance)_2\;+\;(\textit am\;\times\;\% abundance)_3}{\sum abundance}[/tex]

Where, atomic mass and abundance of isotope 1, has been [tex](am\;\times\; \rm \% abundance)_1=(79.52\;\times\;180)\;\rm u[/tex]

The atomic mass and abundance of isotope 2, has been [tex](am\;\times\; \rm \% abundance)_2=(100\;\times\;184)\;\rm u[/tex]

The atomic mass and abundance of isotope 3, has been

[tex](am\;\times\; \rm \% abundance)_3=(82.98\;\times\;186)\;\rm u[/tex]

The sum of abundance, has been, [tex]\sum abundance=79.52\;+\;100\;+\;82.98[/tex]

Substituting the values for calculating amu:

[tex]\\amu=\dfrac{(79.52\;\times\;180)\;+\;(100\;\times\;184)\;+\;(82.98\;\times\;186)\;amu}{79.52\;+\;100\;+\;82.98} \\amu=\dfrac{14,313.6\;+\;18,400\;+\;15,434.28}{262.5} \\amu=183.42[/tex]

The average atomic mass of element X has been 183.42 amu.

Since we know that one atm= 760 torr, we can compute the following calculation:

Remember sig figs (3) to round it to 0.976 atm

[tex]\frac{742 torr}{1}[/tex]*[tex]\frac{1 atm}{760 torr}[/tex]=0.976316=0.976 atm
