1-The chemical potential energy of bond A is greater than the chemical potential energy of bond B. Which statement best explains

this observation?(1 point)
a-The atoms in bond A are larger than the atoms in bond B.

b-The atoms in bond A have fewer bonds between them than the atoms in bond B.

c-The atoms in bond A are held more tightly together than the atoms in bond B.

d-The atoms in bond A are farther apart than the atoms in bond B.



2-Which statement about the bond energies of nitrogen, iodine, and fluorine gases is correct? (1 point)

The atoms in fluorine gas are held together by a triple bond.

The bond in nitrogen gas is the most difficult to break.

Fluorine gas and nitrogen gas have similar bond energies.

Iodine gas has the highest bond energy.

4-The balanced equations for two reactions are shown.

(1) CH4 + N2 + H2 → CH3N + NH3

(2) CH4 + I2 → CH3I + HI

Which statement best explains why reaction 1 requires a greater input of energy than reaction 2?

(1 point)

The bond energy of the reactants in reaction 1 is greater than the bond energy of the reactants in reaction 2.

The number of bonds in the reactants in reaction 1 is greater than the number of bonds in the reactants in reaction 2.

The number of reactants in reaction 1 is greater than the number of reactants in reaction 2.

The bond energy of the products in reaction 1 is less than the bond energy of the products in reaction 2.



5-Chlorine and bromine are in the same group in the periodic table. The bond energy of a Cl–Cl bond is 240 kJ/mol. The bond energy of a Br–Br bond is 190 kJ/mol. Which statement best explains this difference?(1 point)

Chlorine atoms are larger than bromine atoms.

Bromine atoms are more likely than chlorine atoms to interact with other atoms.

It should be noted that bond A has greater energy because C. The atoms in bond A are held more tightly together than the atoms in bond B.

<h3>Bond</h3>

The relationship between the bond energies of nitrogen, iodine, and fluorine gases is that the bond in nitrogen gas is the most difficult to break.

From the information given, the molecule with the greatest bid energy is CH4. The bind energy measures the bond strength that the chemical bond has.

Also, the bond energy of the reactants in reaction 1 is greater than the bond energy of the reactants in reaction 2. Due to this, reaction 1 requires a greater input of energy than reaction 2.

Lastly, the difference in the bond energy of Chlorine and Bromine is that Bromine has more electron levels than chlorine.

NaOH (aq) + HCl(aq) H2O + NaCl (aq)
yuradex [85]

Answer:

The answer to your question is 0.005

Explanation:

Data

Volume of NaOH = 25 ml

[NaOH] = 0.2 M

moles of NaOH = ?

To solve this problem is not necessary to have the chemical reaction. Just use the formula of Molarity and solve it for moles.

Formula

Molarity = moles / volume

-Solve for moles

moles = Molarity x volume

-Convert volume to liters

          1000 ml ---------------- 1 l

              25 ml ---------------- x

               x = (25 x 1) / 1000

               x = 0.025 l

-Substitution

moles = 0.2 x 0.025

-Result

moles = 0.005
