Does this equation show that transmutation has taken place during decay? why or why not?

61/28 ni=61/28 ni + y

a. yes, because the numbers of nucleons and atoms are conserved

b. no, because high-energy electromagnetic waves are emitted

c. no, because there is conservation of the number of atoms as well as the number of nucleons

d. yes, because nickel atoms remain nickel atoms with the same number of neutrons

Answers

Answer 1

The equation is not a transmutation because there is conservation of the number of atoms as well as the number of nucleons; option C.

What is transmutation?

Transmutation refers to the artificial synthesis of new elements by a nuclear reaction of the original element and nuclear particles.

In transmutation, a new element is formed and the atomic number changes.

Based on the above, it can be concluded that the given equation is not a transmutation because there is no change in atomic and nucleon number.

2.86 is the rong answer

54.0 g Al reacts with 64.0 g O2 to
form Al2O3 according to the equation.
4A1+30₂ → 2Al2O3
Al: 26.98 g/mol Al2O3: 101.96 g/mol
How many grams of Al2O3 form
from 54.0 g Al?
[?] g Al₂O3

Answers

Answer:

102 g Al₂O₃

Explanation:

To find the mass of Al₂O₃, you need to (1) convert grams Al to moles Al (via molar mass), then (2) convert moles Al to moles Al₂O₃ (via mole-to-mole ratio from reaction coefficients), and then (3) convert moles Al₂O₃ to grams Al₂O₃ (via molar mass). It is important to arrange the ratios in a way that allows for the cancellation of units. The final answer should have 3 sig figs to reflect the given values.

Molar Mass (Al): 26.98 g/mol

Molar Mass (Al₂O₃): 101.96 g/mol

4 Al + 3 O₂ ---> 2 Al₂O₃

What is Significant figures ?

The digits of a number that are used to express it to the required degree of accuracy, starting from the first non-zero digit.

The given chemical equation ;

4NH₃ + 5O₂ ---> 4NO + 6H₂O

Therefore,

4 moles of NH₃ reacts with 5 moles of O₂.

i.e,

68 g of NH₃ reacts with 160g of O₂.

Therefore,

9.98 g of NH₃ reacts with :

      = 160/68 x 9.98

      = 23.4 g of O₂ (up to 3 significant figure)

H = 1.01 g/mol, O = 16.00 g/mol
How many moles of LICIO4 are present?

[?] mol LICIO4

Answers

Answer:

The number of moles of H₂O is 0.135 mol.

The number of moles of LiClO₄ is 0.0449 mol.

Explanation:

Mole is an important standard unit used for the measurement of large quantities of atoms, molecules, or other particles. One mole is equal to 6.022×10²³ units.

The number of moles of a substance is calculated by:

[tex]\frac{mass of substance}{molecular weight of substance}[/tex]

To find the number of moles of H₂O:

Mass of H₂O in the sample = 2.43g

The molecular weight of H₂O = 18.02g

Number of moles = [tex]\frac{2.43}{18.02}[/tex] = 0.135 mol.

To find the number of moles of LiClO₄:

Mass of LiClO₄ given = 4.78g

The molecular weight of LiClO₄ = 106.39g

Number of moles = [tex]\frac{4.78}{106.39}[/tex] = 0.0449 mol.

The 225 g FeCl2 is about 1.8 moles.
What is the molar concentration of
the solution if the total volume is
450 mL?

Answers

Answer:

[tex]4 \frac{mol}{l} [/tex]

Explanation:

From the question, we have been asked to find the molarity of FeCl2 having a volume of 450 mL,

We have been provided with 225 g which is proportional to 1.8 moles.

We know that molarity of any solution should be in mol/L.

1 mole contained in 1 L means it has a molarity of 1 mol/L

Let's convert 450 mL to Litres which is,

[tex] \frac{450}{1000} litres[/tex]

= 0.450 L

Thus,

1 mole is contained in 1L

x moles are contained in 0.450 L

Hence,

x mole/molarity = {1 mole x 1 L}/{0.450 L}

= 4 mol/L

Therefore 4 mol/L is the molar concentration.
