What is the name of the alkane having five carbons?
Tatiana [17]

Explanation:

Alkanes are the simple hydrocarbons that have only carbon and hydrogen atoms attached to each other through single bonds.

General chemical formula of an alkane is C_{n}H_{2n+2}, where n is any integer.

For example, if n = 5 then formula of the alkane will be as follows.

                                C_{n}H_{2n+2}

                             = C_{5}H_{2(5)+2}

                             = C_{5}H_{12}

A suffix "-ane" is added in the name of an alkane. So, an alkane with five carbon atoms will be known as pentane.

Even at high T, the formation of NO is not favored:
Readme [11.4K]

Answer:

3,16x10⁻³M

Explanation:

For the reaction:

N₂(g) + O₂(g) ⇄ 2NO(g). The kc is defined as:

kc = [NO]² / [N₂] [O₂] = 4,10x10⁻⁴ <em>(1)</em>

If you add in a 1,0L container 0,25 mol of N₂ and 0,10 mol of O₂, concentrations in equilibrium will be:

[N₂] = 0,25M - x

[O₂] = 0,10M - x

[NO] = 2x

Replacing in (1):

[2X]² / [0,25-x] [0,10-x] = 4,10x10⁻⁴

[2X]² / 0,025 - 0,35x + x²= 4,10x10⁻⁴

4X² = 4,10x10⁻⁴x² - 1,435x10⁻⁴x + 1,025x10⁻⁵

3,99959x² + 1,435x10⁻⁴x - 1,025x10⁻⁵ = 0

Solving for x:

x = -0,0016 (<em>Wrong answer, there is no negative concentrations</em>)

x = 0,00158 (<em>Right answer</em>)

As molar concentration of NO in equilibrium is 2x:

[NO] = 2x = 2×0,00158 = <em>3,16x10⁻³M</em>

I hope it helps!

You have 363 mL of a 1.25M potassium chloride solution, but you need to make a 0.50M potassium chloride solution. How many milli
maxonik [38]

Answer:- 544.5 mL of water need to be added.

Solution:- It is a dilution problem. The equation used for solving this type of problems is:

M_1V_1=M_2V_2

where, M_1 is initial molarity and  M_2 is the molarity after dilution. Similarly,  V_1 is the volume before dilution and  V_2 is the volume after dilution.

Let's plug in the values in the equation:

1.25M(363mL)=0.50M(V_2)

V_2=\frac{1.25M(363mL)}{0.50M}

V_2=907.5mL

Volume of water added = 907.5mL - 363mL  = 544.5 mL

So, 544.5 mL of water are need to be added to the original solution for dilution.
