A model of fossils formed on land, on the shore, and in water was set up in Ms. Bill’s classroom. One of the students commented

that the model gave her the wrong idea about the types of fossils found in each location. Why did the student make that comment?A) You have no idea where the pollen grains come from.B) The model shows clam shells as fossils more than once.C) The model is very limited and shows only a few of the many types of fossils.D) The model does not provide information about the type of rock in which fossils form.

Answer:

d.- The model does not provide information about the type of rock in which fossils form.

Explanation:

The fossils can be located in different parts like on land, shore and water. But, they were formed at different time, that means, they live in different ages, that is the reason why the model need to include the type of rock. Remember fossil form at different ages and with the pass of time different layers of rock formed.

Hope this info is useful.

Answer:

Option D. he model does not provide information about the type of rock in which fossils form.

Explanation:

Fossil are formed in different rock types. These are formed in the different rock types. The formation fossils involves two things:

1. temperature

2. pressure

Great heat and pressure are involved in the formation of these fossils. These are thought to be formed about 150 billion years ago. These were formed into  different types mainly into corals, shale, and in other cases fossil fuels like coal, oil and natural gases.

The distribution of fossil fuels clearly indicate the rock type they are formed in. For instance, oil is formed in stratified (layered) rocks.

Hence option D is correct.

What is the OH- ion concentration, in moles per liter, of an aqueous solution with a pH of 7?
topjm [15]

Answer:

B

Explanation:

the pH scale is based on the function

1x10-14

So since pH is neutral the concentration of OH and H must be equal hence the only option in which the concetration would [OH]{H}= 1x10-14 would be when both are equal so it cannot be a or d and when they are expressed in concetration so the only option is B.

Following the instructions in your lab manual, you have titrated a 25.00 mL sample of 0.0100 M KIO3 with a solution of Na2S2O3 o
vivado [14]

<u>Answer:</u>

<u>For 1:</u> The amount of potassium iodate that were titrated is 2.5\times 10^{-4} moles

<u>For 2:</u> The amount of sodium thiosulfate required is 1.25\times 10^{-4} moles

<u>Explanation:</u>

  • <u>For 1:</u>

To calculate the number of moles for given molarity, we use the equation:

\text{Molarity of the solution}=\frac{\text{Moles of solute}\times 1000}{\text{Volume of solution (in L)}}

Molarity of KIO_3 solution = 0.0100 M

Volume of solution = 25 mL

Putting values in above equation, we get:

0.0100M=\frac{\text{Moles of }KIO_3\times 1000}{25}\\\\\text{Moles of }KIO_3=\frac{0.0100\times 25}{1000}=0.00025mol

Hence, the amount of potassium iodate that were titrated is 2.5\times 10^{-4} moles

  • <u>For 2:</u>

The chemical equation for the reaction of potassium iodate and sodium thiosulfate follows:

2KIO_3+Na_2S_2O_3\rightarrow K_2S_2O_3+2NaIO_3

By Stoichiometry of the reaction:

2 moles of potassium iodate reacts with 1 mole of sodium thiosulfate

So, 0.00025 moles of potassium iodate will react with = \frac{1}{2}\times 0.00025=0.000125mol of sodium thiosulfate

Hence, the amount of sodium thiosulfate required is 1.25\times 10^{-4} moles
