If 10.23 moles of NH3 were produced, how many moles of N2 would be required?

Chemistry
1 answer:
Dima020 [189]3 years ago
3 0

Answer:

the number of moles of N_2 required is 5.12 moles

Explanation:

The computation of the number of moles of N_2 required is shown below:

N₂ +  3H₂ → 2NH₃

Here the nitrogen moles and hydorgen would be compared  

NH₃  :  N₂

2 :  1

10.23  : 1 ÷ 2 × 10.23 = 5.12mol

Hence, the number of moles of N_2 required is 5.12 moles

Therefore the same would be considered and relevant too

How is the polarity of a bond different from the polarity of a molecule?
Andreyy89

Answer:

A polar bond is one where the charge distribution between the two atoms in the bond is unequal. A polar molecule is one where the charge distribution around the molecule is not symmetric. It results from having polar bonds and also a molecular structure where the bond polarities do not cancel.

1) A light bulb takes in 30 of energy per second. It transfers 3j as use
natta225 [31]

Answer:

\boxed{\text{10 \%}}

Explanation:

The formula for efficiency is  

\begin{array}{rcl}\text{Efficiency} & = & \dfrac{\text{useful energy out}}{\text{energy in}} \times 100 \,\% \\\\\eta & = & \dfrac{w_{\text{out}}}{w_{\text{in}} } \times 100 \,\%\\\end{array}

Data:

Useful energy =  3 J

Energy input  = 30 J

Calculation:

\begin{array}{rcl}\eta & = & \dfrac{\text{3 J}}{\text{30 J}} \times 100 \,\%\\\\\eta & = & 10 \, \%\\\end{array}\\\text{ The efficiency is }\boxed{\textbf{10 \%}}

If you dispense 40 ml of hexane, but it turns out you only need 5 ml, what should you do with the remainder?
Natasha2012 [34]

After subtracting the volume needed from the volume dispensed, we got a remainder of 35ml

<h3>Subtraction of Numbers</h3>

Given Data

  • Volume of Hexane dispensed = 40ml
  • Volume needed = 5 ml

Let us compute the amount of excess hexane/ the volume that will remain

Remainder = The difference in volume dispensed and the volume needed

Remainder = 40-5

Remainder = 35 ml

The remainder is 35ml
