electron dot structure

Explanation:

Chemical reactions are driven by transfer or sharing of electrons between two or more atoms. To show a specie that is reactive, a sound knowledge of the distribution of electrons in the atom is necessary.

The electron dot structure shows only chemical symbol of the element surrounded by dots which represents the valence electrons.
The chemical symbol represents the nucleus and all electrons except the valence ones.
The dots arranged on the four sides are called lone pairs. Those that are unpaired are called odd electrons.
Chlorine has 7 valence electrons in its outermost shell.
It is made up of 3 lone pairs and 1 odd pair of electron.
The odd pair accounts for the reason why chlorine is very reactive.
It will only require just one electron to join the odd pair so as to complete the octet and be like the noble gases.

What mass of iron (III) nitrate will be in 129.8ml of a 0.3556 molar aq iron (III) nitrate solution?

Anvisha [2.4K]

<u>Answer:</u> The mass of iron (III) nitrate is 11.16 g/mol

<u>Explanation:</u>

To calculate the mass of solute, we use the equation used to calculate the molarity of solution:

$\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}$

We are given:

Molarity of solution = 0.3556 M

Molar mass of Iron (III) nitrate = 241.86 g/mol

Volume of solution = 129.8 mL

Putting values in above equation, we get:

$0.3556M=\frac{\text{Mass of iron (III) nitrate}\times 1000}{241.86 g/mol\times 129.8}\\\\\text{Mass of iron (III) nitrate}=11.16g$

Hence, the mass of iron (III) nitrate is 11.16 g/mol

In a certain chemical reaction Compound A combines with Compound B to produce Compound C (and no other products). Measurements w

Karo-lina-s [1.5K]

Answer:

Theoretical yield of C = 7.9 g

Actual amount of C isolated = 5.0 g

Explanation:

Given that in the reaction, Compound A combines with Compound B t o produce Compound C and no other products, the reaction is a combination reaction. The equation of the reaction is given below:

A + B ---> C

Part A:

From the measurement of the masses of A and B present before and after the reaction, the following values were obtained:

Initial mass of A = 4.0 g

Final mass of A = 0.0 g

Mass of A used up + 4.0 - 0.0 = 4.0 g

Initial mass of B = 9.0 g

Final mass of B = 5.1 g

Mass of B used up = 9.0 - 5.1 = 3.9 g

According to the law of conservation of mass, matter can neither be created nor destroyed but can change from one form to another. Therefore, theoretical yield of C equal the sum of the masses of A and B used up.

Theoretical yield of C = 4.0 + 3.9 = 7.9 g

Part B:

Given that the percent yield is 63.0 % = 0.63

Actual amount of C isolated = 0.63 * 7.9 = 5.0 g
