Answer:

<em>All of the carbon-carbon bonds have exactly the same lengths - somewhere between single and double bonds. There are delocalized electrons above and below the plane of the ring. The presence of the delocalized electrons</em>

. Given the following reaction: ___N2 (g) + ___H2 (g)→___ NH3 (g)If 2.00 L of ammonia (NH3) are produced in the reaction between

Butoxors [25]

In this question, we have to find how many liters of Nitrogen gas is used to make 2.00 Liters of NH3, and the first thing we have to do is set up the properly balanced equation:

N2 + 3 H2 -> 2 NH3, now the reaction is balanced

According to the balanced equation, the molar ratio between NH3 and N2 is 2:1, which means with 1 mol of N2, we can produce 2 moles of NH3, but now we have to match the number of moles equivalent to 2 Liters of NH3

At STP (Standard Temperature and Pressure), 1 mol of gas is equal to 22.4 Liters of Volume, which means, 2 moles of gas will be equal to:

22.4 L = 1 mol

2 L = x moles

x = 0.089 moles of NH3 in 2 Liters

Now, according to the molar ratio, if we have 0.089 moles of NH3, we will have:

2 NH3 = 1 N2

0.089 NH3 = x N2

x = 0.0445 moles of N2

Now to find the volume, we will use that information about STP again

1 mol = 22.4 Liters

0.0445 moles = x Liters

x = 1 Liter of Nitrogen gas is required

Calculate the mass of 6.9 moles of nitrous acid (HNO2). Explain the process or show your work by including all values used to de

AlexFokin [52]

Answer:- 324.3 grams.

Solution:- We have been given with 6.0 moles of nitrous acid and asked to calculate it's grams. Moles to grams is a unit conversion and for doing this conversion we multiply the given moles by the molar mass of the compound.

Molar mass is the formula mass and to calculate this the atomic masses of each atom are multiplied by their respective subscripts that is the number of the atom in the compound .

For example, $NO_2$ has one nitrogen atom and one oxygen atom. So, the molar mass of this is = atomic mass of N + 2(atomic mass of O)

= 14 + 2(16)

= 14 + 32

= 46 gram per mol

gram per mol is the unit of molar mass. So, the molar mass of $NO_2$ is 46 grams per mol.

Let's calculate the molar mass of nitrous acid using the same concept.

molar mass of [ $HNO_2$ = 1 + 14 + 2(16)

= 1 + 14 + 32

= 47 grams per mol

Now, 6.9 moles of nitrous acid could easily be converted to grams as:

$6.9molHNO_2(\frac{47g}{1mol})$

= 324.3 g

Hence, the mass of 6.9 moles of nitrous acid is 324.3 grams.
