How many moles of NO gas are formed from 2.25 moles of nitrogen?
VikaD [51]

Hey there!

A mole is measured in atoms, molecules, particles. It's kind of a loose sort of measurement, just unit of the substance.

Since there is a ratio of 1 to 1 nitrogen to oxygen, there will be the same amount of molecules as atoms of nitrogen.

2.25 moles of NO gas are formed from 2.25 moles of nitrogen.

Hope this helps!

Question 8 (5 points)
Fynjy0 [20]

[H+][OH-]=10-¹⁴

We are using this formula because we need to find the H+

substitute the value given for hydronium ion for OH-

[H+][4.19×10⁵]=10-¹⁴

[H+]=10-¹⁴÷4.19×10⁵

[H+]=2.387×10-¹⁹

Then the pH of the solution will be

pH= –log¹⁰ [H+]

pH = –log¹⁰ [2.387×10-¹⁹]

pH= –log¹⁰2.387+19log¹⁰

= –0.378+19

pH =18.622

Answer:

Mass of HCN produced = 6.75 g

Explanation:

Reaction is as follows:

2NH_3+3O_2+2CH_4 \rightarrow 2HCN + 6H_2O

First calculate the no. of moles of each chemical species.

molecular mass of NH_3 is 17 g/mol

No. of mol of NH_3 = 11.5/17 = 0.676 mol

Molecular mass of O_2 = 32 g/mol

No. of  mol of O_2 = 12/32 = 0.375

Molecular mass of CH_4 = 16 g/mol

No. of  mol of CH_4 = 10.5/16 = 0.656 mol

from the balanced chemical reaction, it is clear that 2-moles ammonia reacts with 3 moles oxygen and 2 moles methane to form 2 moles of HCN.

or, 1-mol ammonia reacts with 1.5 mol oxygen and 1 mol methane to form 1 mol of HCN.

Thus, no. of oxygen present is less than required and so it will act as limiting reagent.

From the chemical equation,

3 moles oxygen produces 2 moles HCN

or one mole oxygen produces (2/3) moles HCN

0.375 moles oxygen produces (2/3) × 0.375 HCN = 0.25 moles of HCN  

molar mass of HCN = 27 g/mole

Mass = mol × molar mass

mass of HCN = 27 × 0.25 = 6.75 g
