Answer: Resources are characterized as renewable or nonrenewable

- a renewable resource can replenish itself at the rate it is used such as solar energy, wind energy, hydro energy, and tidal energy.

- a nonrenewable resource has a limited supply such as coal, gas, nuclear energy, and fossil fuels.

When n = 4, l = 2, and ml = -1, to what orbital type does this refer?

Leya [2.2K]

will tell you the subshell type, so you are dealing with a d orbital.

ml will tell you the orientation of the orbital, there is no distinction between the orbitals so -1 doesnt specifically mean anything.

The isomerization of methylisonitrile to acetonitrile is first order in CH3NC. CH3NC(g) → CH3CN(g) The half life of the reaction

sasho [114]

<u>Answer:</u> The rate constant for the given reaction is $4.33\times 10^{-6}s^{-1}$

<u>Explanation:</u>

For the given chemical equation:

$CH_3NC(g)\rightarrow CH_3CN(g)$

We are given that the above equation is undergoing first order kinetics.

The equation used to calculate rate constant from given half life for first order kinetics:

$t_{1/2}=\frac{0.693}{k}$

The rate constant is independent of the initial concentration for first order kinetics.

We are given:

$t_{1/2}$ = half life of the reaction = $1.60\times 10^5s$

Putting values in above equation, we get:

$k=\frac{0.693}{1.60\times 10^5s}=4.33\times 10^{-6}s^{-1}$

Hence, the rate constant for the given reaction is $4.33\times 10^{-6}s^{-1}$

You wish to make a 0.299 M hydroiodic acid solution from a stock solution of 6.00 M hydroiodic acid. How much concentrated acid

Art [367]

Answer:

$V_1=2.49mL$

Explanation:

Hello,

In this case, considering that the moles of hydrioiodic acid remain unchanged during the dilution process:

$n_{HI}=n_{HI}$

One could apply the following equality in terms of molarity:

$V_1M_1=V_2M_2$

Whereas the subscript 1 accounts for the solution before the dilution and 2 after the dilution, therefore, the required volume of 6.00 M acid is:

$V_1=\frac{V_2M_2}{M_1} =\frac{50.0mL*0.299M}{6.00M}=2.49mL$

Best regards.
