Answers

Answer 1

Answer:

3.27*(10^-5) M

Explanation:

For 25°C:

[H3O+] *[OH-] =(10^-14)-->

[OH-]=(10^-14)/[H3O+]-->

[OH-]=(10^-14)/(3.06*10^-10)-->

[OH-]=3.27*(10^-5) M

The gas phase decomposition of hydrogen peroxide at 400 °C

H2O2(g)H2O(g) + ½ O2(g)

is second order in H2O2 with a rate constant of 0.650 M-1 s-1.

If the initial concentration of H2O2 is 8.00×10-2 M, the concentration of H2O2 will be 1.70×10-2 M after
seconds have passed.

Answers

Answer:

t = 71.3 s

Explanation:

Hello there!

In this case, since the second-order integrated law is given by the following equation:

[tex]\frac{1}{[H_2O_2]} =\frac{1}{[H_2O_2]_0}+kt[/tex]

Thus, given the initial and final concentration of hydrogen peroxide and the rate constant, we obtain the following time:

[tex]\frac{1}{[0.0170M]}-\frac{1}{0.0800M}=0.650M^{-1}s^{-1}t\\\\t=\frac{46.32M^{-1}}{0.650M^{-1}s^{-1}} \\\\t=71.3s[/tex]

Why is NH3 not considered a base under the Arrhenius definition of acids and bases?

SELECT AN ANSWER

a. It does not react with acids.
b. NH3(aq) does not contain OH- ions.
c. NH3 is considered a base under the Arrhenius definition, but not under the Bronsted-Lowry definition.
d. It does not cause a color change when mixed with an acid-base (pH) indicator.

Answers

Answer:

b. NH3(aq) does not contain OH- ions.

Explanation:

According to Arrhenius in his definition, a base is a substance that has the ability to increase the hydroxyll ion (OH-) of an aqueous solution. In other words, Arrhenius bases dissociates into OH- when dissolved in water.

According to this question, ammonia (NH3) will not be considered an Arrhenius base because it does not contain OH-. This means that ammonia (NH3) cannot dissociate into hydroxyll ion when dissolved in water.

Hence in the Sodium hydroxide, methyl orange will turn into yellow color and in Sulfuric acid shows red color. Red litmus will turn into blue color in the Sodium hydroxide solution.

What is litmus paper?

Litmus paper is a paper which is used to identify the acidity or basicity of any solution.

Sulfuric acid is acidic in nature, and red litmus paper shows no effect in this acid as red paper change into blue in the presence of base. Methyl orange is an indicator and it shows red color in the acidic medium.Sodium hydroxide is basic in nature and red litmus paper will change into blue in this solution and color of methyl orange changes from red to yellow in the basic solution.

Which of these things would you expect to have cells with both mitochondria
and chloroplasts?
A. Squirrel
B. Shark
C. Hummingbird
D. Grass​

Answers

Answer:

D. Grass​

Explanation:

Every living organism must contain one or more cells to be considered "living". Each cell, however, contains certain structures that perform specific roles called ORGANELLES. These organelles are of different types and hence, perform different tasks. For example, mitochondria is the power house of a cell i.e. site of energy production, and hence, is found in every eukaryotic cell.

On the other hand, chloroplast is an organelle designed to perform photosynthesis, which only occurs in plant cells. Since only plant cells can undergo photosynthesis, only plant cells can contain chloroplast. Hence, according to this question, GRASS as a type of plant is an organism that will contain both mitochondria and chloroplast in its cells.

Which one of the following statements concerning the length of carbon-carbon single, double, and triple covalent bonds is true?

[tex]\color{Blue}\huge\boxed{Answer} [/tex]

D. The carbon-carbon single, double, and triple bonds all have the same length.

The statement concerning the length of carbon-carbon single, double, and triple covalent bonds which is true is: D. The carbon-carbon single, double, and triple bonds all have the same length.

A chemical bond can be defined as the forces of attraction between ions, crystals, atoms or molecules which are typically responsible for the formation of chemical compounds. Thus, a chemical bond is a force that holds atom together and binds crystals, ions or molecules together, so as to form a chemical compound.

Generally, there are three (3) main types of chemical bonds and these includes:

Hydrogen bonds.Ionic bonds.Covalent bonds.

A covalent bond can be defined as a type of bond that typically involves the sharing of electrons between the atoms of a chemical element. The type of bond formed between two or more carbon atoms is a covalent bond. Hence, carbon atoms can either form a single, double, or triple covalent bonds with the same length.

In conclusion, the length of carbon-carbon single, double, and triple covalent bonds are all the same.

Aqueous hydrochloric acid will react with solid sodium hydroxide to produce aqueous sodium chloride and liquid water . Suppose 1.5 g of hydrochloric acid is mixed with 2.67 g of sodium hydroxide. Calculate the maximum mass of water that could be produced by the chemical reaction. Round your answer to significant digits.

Answers

Answer: The maximum amount of water that can be produced is 0.74 g

Explanation:

To calculate the number of moles, we use the equation:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex]      .....(1)  

Putting values in equation 1, we get:

[tex]\text{Moles of hydrochloric acid:}=\frac{1.5g}{36.5g/mol}=0.041mol[/tex]

[tex]\text{Moles of sodium hydroxide}=\frac{2.67g}{40g/mol}=0.067mol[/tex]

The chemical equation for the reaction is

[tex]HCl+NaOH\rightarrow NaCl+H_2O[/tex]

By Stoichiometry of the reaction:

1 mole of HCl reacts with 1 mole of NaOH

So, 0.041 moles of HCl will react with = [tex]\frac{1}{1}\times 0.041=0.041mol[/tex] of NaOH

As, given amount of NaOH is more than the required amount. So, it is considered as an excess reagent. Thus, HCl is considered as a limiting reagent because it limits the formation of product.

By Stoichiometry of the reaction:

1 mole of HCl produces = 1 mole of water

So, 0.041 moles of HCl will produce = [tex]\frac{1}{1}\times 0.041=0.041moles[/tex] of water

Mass of water=[tex]moles\times {\text{Molar Mass}}=0.041mol\times 18g/mol=0.74g[/tex]

Thus the maximum amount of water that can be produced is 0.74 g
