How does the chemical formula relate to the number of particles that result from the dissociation of molecule?

1 answer:

5 0

The chemical formula would dictate how many ions are present in a solution. It tells how many of what ion would dissociate in the solution. In every chemical reaction or dissociation reaction, it is important to remember that the number of each atoms on each side would be equal.

Answer:

58.702

Explanation:

Data obtained from the question include:

Mass number of isotope 1 (M1) = 57.93

Abundance of isotope 1 (M1%) = 67.76%

Mass number of isotope 2 (M2) = 59.93

Abundance of isotope 2 (M2%) = 26.16%

Mass number of isotope 3 (M3) = 60.93

Abundance of isotope 3 (M3%) = 1.25%

Mass number of isotope 4 (M4) = 61.93

Abundance of isotope 4 (M4%) = 3.66%

Mass number of isotope 5 (M5) = 63.93

Abundance of isotope 5 (M5%) = 1.16%

Relative atomic mass =...?

The relative atomic mass(RAM) of the element can be obtained by doing the following:

RAM = [(M1×M1%) /100] +[(M2×M2%) /100] + [(M3×M3%) /100] + [(M4×M4%) /100] + [(M5×M5%) /100]

RAM = [(57.93×67.76)/100] + [(59.93×26.16)/100] + [(60.93×1.25) /100] + [(61.93×3.66)/100] + [(63.93×1.16)/100]

RAM = 39.253 + 15.678 + 0.762 + 2.267 + 0.742

RAM = 58.702

Therefore, the relative atomic mass (RAM) of the element is 58.702

Chemistry question<br>label them<br>reactants, products,activation energy etc

sertanlavr [38]

In the illustration A would be the reactants and E would be the products. B would be the activation energy (Ea), C would be the potential energy of reactants, F would be the potential energy of products, and D would be the potential energy change.

<h3>Energy Diagram</h3>

The energy diagram shows the energy states of the components of reactions.

From the diagram, A being the reactant becomes E, the product. The minimum energy that A needs to overcome to arrive at the product (activation energy) is B.

The energy state of the reactant A before becoming the product is C while that of the product E is F. The difference in the energy state of A and E is D.

The volume of a diamond is found to be 2.8 ml. what is the mass of the diamond in carats?

Helen [10]

Answer:

49.14 carat.

Explanation:

From the question given above, we obtained the following data:

Volume of diamond = 2.8 mL

Mass of diamond (in carat) =.?

Next, we shall determine the mass of diamond in grams (g). This can be obtained as follow:

Volume of diamond = 2.8 mL

Density of diamond = 3.51 g/mL

Mass of diamond ( in grams) =?

Density = mass /volume

3.51 = mass /2.8

Cross multiply

Mass of diamond (in g) = 3.51 × 2.8

Mass of diamond (in g) = 9.828 g

Finally, we shall Convert 9.828 g to carat. This can be obtained as follow:

1 g = 5 carat

Therefore,

9.828 g = 9.828 g /1 g × 5 carat

9.828 g = 49.14 carat.

Therefore, the mass of the diamond in carat is 49.14 carat.

What must the value of a conversion factor always be?

storchak [24]

Answer:

One or unity or 1

Explanation:

For example,

1 min =60 s

If we divide each side of the equation by 1 min, we get

$1 = \dfrac{\text{60 s}}{\text{1 min}}$

If we divide each side of the equation by 60 s, we get

$\dfrac{\text{1 min}}{\text{60 s}} = 1\\\\\text{Thus, both conversion factors, $\dfrac{\text{60 s}}{\text{1 min}}$ and $\dfrac{\text{1 min}}{\text{60 s}}$, equal 1.}$
