The Lewis dot model of a molecule is shown. A visual diagram of a PCl3 molecule is shown. Phosphorous is the central atom with a

horizontal line connecting to each of the three Chlorine atoms around it. Phosphorous has a pair of dots on it. Each of the three chlorine atoms have a pair of three dots on it. Based on the model, which of the following is true?
( a. The electronegativity difference between phosphorous and chlorine is greater than 1.7.

( b. Each chlorine has three non-bonded pairs and one bonded pair of electrons.

( c. Phosphorous has three non-bonded pairs and one bonded pair of electrons.

( d. Phosphorous has three valence electrons in the outermost energy level.

Answer:

b. Each chlorine has three non-bonded pairs and one bonded pair of electrons.

Explanation:

Chlorine has three valance electrons. Each Cl atom forms a single covalent bond with the central P atom by sharing a pair of electrons. After forming a single covalent bond each Cl atom is left with six electrons that do not participate in any bond formation or there are three pairs of lone electrons.

How many moles are equal to 3.0x10^23 atoms of germanium? PLS ANSWER WITH WORK!
horrorfan [7]
1 mole=6.02 x 10^23 atoms so how many moles are there in 3.0 x 10^23 we will cross multiply, 1 x 3.0 x 10^23 / 6.02 x 10 ^23. Which will give us 0.498 moles.

From the calculation, the standard free energy of the system is -359kJ.

<h3>What is the standard free-energy?</h3>

The  standard free-energy is the energy present in the system. We have to first obtain the cell potential using the formula;

Ereduction - E oxidation = 0.96 V - 0.34 V = 0.62 V

Using the formula;

ΔG = -nFEcell

ΔG =-(6 * 96500 * 0.62)

ΔG =-359kJ

yuradex [85]

Answer:

Explanation:

Given parameters:

Volume of CO₂ = 24cm³

time taken for the reaction to complete = 8minutes.

Unknown:

rate of reaction

Soution

The reaction rate is a measure of speed of a chemical reaction. It is often calculated using the expression below:

    Reaction rate = \frac{change in concentration of reactant/product}{time taken}

   Reaction rate = \frac{24}{8} = 3cm³/min

In this reaction, 3cm³ of carbon dioxide were produced per minute
