Answer:

The molar mass of NaOH is 40.00 g/mol.

The number of moles of NaOH is equal to the ratio of its mass to molar mass.

The number of moles of NaOH =

40 g/mol

40 g

​

=1,000 mol

The molarity of NaOH solution is the ratio of number of moles of NaOH to total volume of solution in L.

M=

1 L

1 mol

​

=1 M

For the reactionN2(g)+O2(g)?2NO(g)classify each of the following actions by whether it causes a leftward shift, a rightward shif
Soloha48 [4]

Answer: Le Chatleir Principle

Explanation:  The answer of this question can be easily explanied through the Le Chatleir Principle which states that In order to maintain the equilibrium of the reaction, the stress applied to that particular direction will move the equilibrium to the opposite direction in which the stress has been applied.

The given reaction is -

      N_{2}(g)+O_{2}(g)\rightleftharpoons 2NO(g)

If the amount of the oxygen is reduced to half and is being doubled, then the reaction will move in froward direction that is a rightward shift. Same situation will arise in option c and d.

If the amount of nitrogen monoxide is reduced to half or being doubled, the reaction will move towards backward direction that is a leftward reaction.

Does Graphene come from natural materials? Give an explanation
Gnoma [55]

Answer:

Actually graphene is not occurred in naturally.

Explanation:

graphene is a layer or a sheet which is extracted from graphite because graphite is layered material. most of the time famous scotch tape may produce graphene but you can't identify it without using electron microscope

(a) starting with solid sucrose, c12h22o11, describe how you would prepare 250 ml of a 0.250 m sucrose solution. (b) de- scribe
Anna007 [38]

a. We first calculate the moles of sucrose needed

moles sucrose = 0.250 M * 0.25 L

moles sucrose = 0.0625 mol

 

The molar mass of sucrose 342.3 g/mol, so the mass of sucrose needed is:

mass sucrose = 0.0625 mol * 342.3 g/mol

mass sucrose = 21.4 grams

 

So simply dissolved about 21.4 grams of sucrose in 250 mL solution.

 

b. We use the formula:

M1 V1 = M2 V2

1.50 M * V1 = 0.100 M * 0.350 L

V1 = 0.0233 L = 23.3 mL

 

So simply take 23.3 mL of solution from 1.50 M then dilute it with water until 350 mL to make 0.100 M.

A solution is prepared by mixing 0.10 of 0.12 M sodium chloride with 0.23 L of a 0.18 M magnesium chloride solution. What is the
Ad libitum [116K]

Answer:

pCl⁻ = 0.54

Explanation:

First we <u>calculate how many Cl⁻ moles are coming from each substance</u>, using the <em>given volumes and concentrations</em>:

  • 0.12 M NaCl * 0.10 L = 0.012 mol NaCl = 0.012 mol Cl⁻
  • 0.18 M MgCl₂ * 0.23 L = 0.0414 mol MgCl₂ = (0.0414 * 2) 0.0828 mol Cl⁻

The final volume of the mixture is = 0.10 L + 0.23 L = 0.33 L

Now we <u>calculate [Cl⁻]</u>, using the<em> total number of Cl⁻ moles and the final volume:</em>

  • [Cl⁻] = (0.012 mol + 0.0828 mol) / 0.33 L = 0.29 M

Finally we <u>calculate the pCl⁻ of the resulting solution</u>:

  • pCl⁻ = -log[Cl⁻]
  • pCl⁻ = 0.54
