Q3) 1.5 mL from the 1.00 M HCl stock solution

Q4) 0.15 mL from the 1.00 × 10⁻¹ M NaOH stock solution

Explanation:

Q3) Determine the amount of 1.00 M HCl stock solution needed to form 100 mL of 1.50 × 10⁻² M HCl solution.

Q4)  Determine the amount of 1.00 × 10⁻¹ M stock NaOH solution needed to form 100 mL of 1.50 × 10⁻² M NaOH solution.

To solve both of the questions we use the following formula:

initial concentration × initial volume =  final concentration × final volume

For Q3 we have:

initial concentration = 1.00 M HCl

initial volume = ?

final concentration =  1.50 × 10⁻² M HCl

final volume = 100 mL

1.00 × initial volume = 1.50 × 10⁻² × 100

initial volume = ( 1.50 × 10⁻² × 100) / 1.00

initial volume = 1.5 mL from the 1.00 M HCl stock solution

For Q4 we have:

initial concentration = 1.00 × 10⁻¹ M NaOH

initial volume = ?

final concentration =  1.50 × 10⁻² M NaOH

final volume = 100 mL

1.00 × 10⁻¹ × initial volume = 1.50 × 10⁻² × 100

initial volume = ( 1.50 × 10⁻² × 100) / 1.00 × 10⁻¹

initial volume = 0.15 mL from the 1.00 × 10⁻¹ M NaOH stock solution

A chemical reaction in which bonds are broken is usually associated with ________. a chemical reaction in which bonds are broken
Reika [66]

Answer:The answer to the question is the release of energy. The bonds that bind a molecules atom's act as a storage of energy. One way it is released is when those bonds are broken and it is released outward in every direction. This breakage results in smaller molecules and not the formation of a larger molecule.

The density of aluminum is 2.70 g/cm3. Apiece of aluminum foil that is 1000 cm on each side has a mass of 440. mg. How thick is
MissTica
Mass/volume = density
mass = (440 mg)*(1g)/(1000mg) = 0.440g
volume = (1000cm)(1000cm)(t)
where t = thickness
density = 2.70 g/cm^3 = (0.440g)/((1000cm)(1000cm)(t))

multiply both sides by 't' and divide both sides by (2.70g/cm^3)

t = (0.440) / ((1000cm)(1000cm)(2.70)) = 1.629x10^-7 cm

t = (1.629 x 10^-7 cm)*(1000000 micrometers)/(1 cm) = 0.1629 micrometers

Answer is t = 0.1629 micrometers

Calculate ΔH o rxn for the following: CH4(g) + Cl2(g) → CCl4(l) + HCl(g)[unbalanced] ΔH o f [CH4(g)] = −74.87 kJ/mol ΔH o f [CCl
anzhelika [568]

Answer:  ΔH for the reaction is -277.4 kJ

Explanation:

The balanced chemical reaction is,

CH_4(g)+Cl_2(g)\rightarrow CCl_4(l)+HCl(g)

The expression for enthalpy change is,

\Delta H=\sum [n\times \Delta H(products)]-\sum [n\times \Delta H(reactant)]

\Delta H=[(n_{CCl_4}\times \Delta H_{CCl_4})+(n_{HCl}\times B.E_{HCl}) ]-[(n_{CH_4}\times \Delta H_{CH_4})+n_{Cl_2}\times \Delta H_{Cl_2}]

where,

n = number of moles

Now put all the given values in this expression, we get

\Delta H=[(1\times -139)+(1\times -92.31) ]-[(1\times -74.87)+(1\times 121.0]

\Delta H=-277.4kJ

Therefore, the enthalpy change for this reaction is, -277.4 kJ
