Its False 

hope that helps 
Burka [1]4 years ago
4 0

Answer:

True.

Explanation:

  • As the amount of temperature is directly measured by the energy contained in the substance. When the average kinetic energy increases the molecules of solids then diffuse into liquid waters and then form gas with the increase in this energy.
  • But to diffuse into another solid the matter must have a surface that allows for the mixing to occur at higher temperature and pressure, which is mostly seen in liquids and gases.

What is the molar mass of sulfur trioxide?
tatyana61 [14]

Answer:

80.07 g/mol

Explanation:

Sulfur's g/mol = 32.07

Oxygen's g/mol = 16.00

32.07 + 16.00(3) = 80.07 g/mol

Consider the following reaction. N2(g) + O2(g) = 2 NO(g) (a) If Kc for this reaction is 1.5 ✕ 10−10, and a reaction system at eq
svet-max [94.6K]

<u>Answer:</u>

<u>For a:</u> The concentration of NO at equilibrium is 5.27\times 10^{-7}M

<u>For b:</u> The value of K_c' is 6.66\times 10^{10}

<u>For c:</u> The correct answer is product favored.

<u>Explanation:</u>

  • <u>For a:</u>

The given chemical reaction follows:

N_2(g)+O_2(g)\rightleftharpoons 2NO(g)

The expression of K_c for above equation follows:

K_c=\frac{[NO]^2}{[N_2][O_2]}

We are given:

K_c=1.5\times 10^{-10}

[N_2]_{eq}=0.043M

[O_2]_{eq}=0.043M

Putting values in above equation, we get:

1.5\times 10^{-10}=\frac{[NO]^2}{0.043\times 0.043}

[NO]=\sqrt{(1.5\times 10^{-15}\times 0.043\times 0.043)}=5.27\times 10^{-7}M

Hence, the concentration of NO at equilibrium is 5.27\times 10^{-7}M

  • <u>For b:</u>

The given chemical reaction follows:

2NO(g)\rightleftharpoons N_2(g)+O_2(g)

The expression of K_c' for above equation follows:

K_c'=\frac{[N_2][O_2]}{[NO]^2}

As, the above reaction is the reverse of equation in part a. So, the value of K_c' will be inverse of K_c

K_c'=\frac{1}{K_c}\\\\K_c'=\frac{1}{1.5\times 10^{-10}}=6.66\times 10^{10}

Hence, the value of K_c' is 6.66\times 10^{10}

  • <u>For c:</u>

There are 3 conditions:

  • When K_{c}>1; the reaction is product favored.
  • When K_{c}; the reaction is reactant favored.
  • When K_{c}=1; the reaction is in equilibrium.

For the reaction in part 'b', the value of K_c' is 6.66\times 10^{10}

The value of K_c' is very high than 1. So, the equilibrium in part 'b' is product favored.

Hence, the correct answer is product favored.

You added 5.00 ml of 0.40 m naoh in methanol to 20.00 ml of cooking oil. Calculate the number of moles of vegetable oil
goldenfox [79]

Answer:

n_{oil}=0.002mol

Explanation:

Hello,

In this case, considering that the sodium hydroxide reacts with the cooking oil, the following relationship is applied:

n_{oil}=n_{NaOH}\\n_{oil}=M_{NaOH}*V_{NaOH}\\n_{oil}=0.4\frac{mol}{L} * 0.005L\\n_{oil}=0.002mol

Best regards.
