A student needs to prepare 50.0 mL of 0.80 M aqueous H2O2 solution. Calculate the volume of 4.6 M H2O2 stock solution that shoul

Degger [83]

Answer:

We need 8.7 mL of the stock solution

Explanation:

Step 1: Data given

Volume of the solution he wants to prepare = 50.0 mL = 0.050 L

Concentration of the solution he wants to prepare = 0.80 M

The concentration of the stock solution = 4.6 M

Step 2: Calculate the volume of the stock solution

C1*V1 = C2*V2

⇒with C1 = the concentration of the stock solution = 4.6 M

⇒with V1 = the volume of the stock solution = TO BE DETERMINED

⇒with C2 = the concentration of the prepared solution = 0.80 M

⇒with V2 = the volume of the prepared solution = 0.050 L

4.6 M * V2 = 0.80 M * 0.050 L

V2 = (0.80 M * 0.050 L) / 4.6M

V2 = 0.0087 L = 8.7 mL

We need 8.7 mL of the stock solution

How is the ocean important to human survival? restate the question

Aneli [31]

Answer:

How is the ocean important to human survival? The air we breathe: The ocean produces over half of the world's oxygen and absorbs 50 times more carbon dioxide than our atmosphere. Climate regulation: Covering 70 percent of the Earth's surface, the ocean transports heat from the equator to the poles, regulating our climate and weather patterns

What is the name of the organic product formed when 2-methylhexan-2-ol is reacted with acidified potassium dichromate under refl

neonofarm [45]

Answer:

We will not have a reaction.

Explanation:

The alcohol 2-methylhexan-2-ol its a tertiary alcohol. Additionally, the reaction of $K_2Cr_2O_7$ and acid medium will produce chromic acid $H_2Cr_2O_7$ with the following reaction:

$K_2Cr_2O_7~+~2H^+->~H_2Cr_2O_7~+~2K^+$

Chromic acid is a strong oxidant, so an oxidation-reduction reaction will take place. But, in this case. we have tertiary alcohol (see figure 1). Primary alcohols are oxidized to aldehydes and aldehydes are oxidized to carboxylic acids. Secondary alcohols are oxidized to ketones and tertiary alcohols can not be oxidized due to the lack of hydrogens on the carbon that is bonded to the "OH" group.

Therefore we will have no reaction.

I hope it helps!

Why is knowing the physical and chemical properties of matter important?

lukranit [14]

Knowing the chemical and physical properties of matter is important when handling them. To know if the matter is safe to handle, whether it is toxic/poisonous or has a vigorous reaction with other substances.
For example sodium (Na) reacts vigorously with water therefore it is stored under paraffin oil.

Hope it helped!
