Using the valence bond method, explain the structure of isocyanic acid in terms of the atomic bond method.
Gala2k [10]

The structure of isocynide is

N=C

What is the importance of VSEPR theory?

Valence bond theory describes the electronic structure of molecule .The theory says that electrons fills the atomic orbitals of an atom within a molecule .

In the structure of isocynide there are triple bonds between Nitrogen and carbon . The bond length is 115.8pm and the bond angle is 180°. There is two pi and one sigma bond .

Use the reaction, which produces ammonia, to answer the question.
zepelin [54]

This problem is providing us with the chemical equation depicting the production of ammonia from nitrogen and hydrogen at equilibrium and asks for the correct change when the concentration of nitrogen is increased. At the end, the answer is the forward reaction would increase to start reducing the concentration of N2.

<h3>Chemical equilibrium</h3>

In chemistry, chemical reactions not always reach a 100-% conversion when reactants get in contact in order to carry out the chemical reaction. Thus, there is a point wherein the concentrations remain the same and is called equilibrium.

In such a way, for this problem, we have the following chemical reaction at equilibrium:

N_2(g) + 3H_2(g) \rightleftharpoons 2NH_3(g)

Now, according to the Le Ch.atelier's principle, an increase in the concentration of any species, shifts the equilibrium away from it, which means that if we increase the concentration of nitrogen, a reactant, the forward reaction will be favored.

Thereby, the correct answer is "the forward reaction would increase to start reducing the concentration of N2".

A scientist performs an experiment where she measures the mass of a piece of metal, pours acid onto the metal,
Sati [7]

Answer:

B (Final mass of the metal)

Explanation:

The independent variable in this experiment is the amount of acid the scientist pours on the metal, and the only variable in the list dependent on the amount of acid poured on the metal is the final mass of the metal. Therefore, the final mass of the metal is the dependent variable in the experiment.

Caustic soda is 19.1 M NaOH and is diluted for household use. What is the household concentration if 10 mL of the concentrated s
olga nikolaevna [1]
Hello!

To calculate the household concentration of NaOH we need to use the dilution formula, clearing for M2, as you can see in the equation below:

M1*V1=M2*V2 \\ \\ V2= \frac{M1*V1}{V2}

Now, we input the values from the data we have onto this equation. M1=19,1 M; V1=10 mL; V2=400 mL, and solve the equation to get the result:

V2= \frac{M1*V1}{V2}= \frac{19,1M*10mL}{400 mL}=0,48M

So, the household concentration of NaOH will be 0,48 M

Have a nice day!

The total number of valence electrons in the phosphate ion is
Vitek1552 [10]

Answer:

32

Step-by-step explanation:

There are two ways you can count the valence electrons.

A. From the Periodic Table

1 × P (Group 15)               =   5

4 × O (Group 16) = 4 × 6 = 24

+3 e⁻ (for the charges)   = <u>  3</u>

                              Total = 32

B. From the Lewis structure

In the <em>Lewis structure</em> (below), each line (bond) represents a pair of bonding electrons, and each dot represents an unbound electron (half a lone pair).

5 lines (bonds)                    = 5 × 2 = 10

3 single-bonded O atoms = 3 × 6 = 18

1 double-bonded O atom              = <u>  4</u>

                                              Total = 32
