Answer: 0.08585 moles of N_2O_5 is needed to produce 7.9 grams of NO_2

Explanation: Moles is calculated by using the formula:

Moles=\frac{\text{Given mass}}{\text{Molar mass}}

Molar mass of NO_2 = 46 g/mol

Number of moles of NO_2=\frac{7.9g}{46g/mol} = 0.1717 moles

For the given chemical reaction:

2N_2O_5\rightarrow 4NO_2+O_2

By Stoichiometry,

4 moles of NO_2 is produced by 2 moles of N_2O_5

So, 0.1717 moles of NO_2 is produced by = \frac{2}{4}\times 0.1717 = 0.08585 moles of N_2O_5

Hence, moles of N_2O_5 is 0.08585 moles.

liubo4ka [24]

Answer:

<h2>0.102 L</h2>

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

P_1V_1 = P_2V_2

Since we are finding the new volume

V_2 =  \frac{P_1V_1}{P_2}  \\

From the question we have

V_2 =  \frac{207000 \times 0.05}{101000}  =  \frac{10350}{101000}  \\  = 0.102475...

We have the final answer as

<h3>0.102 L</h3>

Hope this helps you

How many moles of NaCl could be made by combining 20,000 moles of Na with 2 moles of CI?
GREYUIT [131]

Answer:

None of the above.

Explanation:

The limiting factor of this  is the chlorine. You only have 2 moles of chlorine.

2Na + Cl_2 ==> 2*NaCl

The equation tells you that for every mol of Cl2 that you have, you require 2 moles of Na and you get 2 moles of NaCl

So what that means is that if you have 2 mols of Cl2, you need just 4 moles of Na, and you will get 4 mols of NaCl

Since 4 is not one of your choices, the answer is none of the above
