Answer:

As the leaf decomposes, the carbon of the leaf is left in the rock.

Explanation:

A fossil is any rest of the organism or its activity that has a minimum age of 10 thousand years. That is, fossils are the remains or marks of extinct animals, which after death their bodies or marks of their activity have been preserved in some way.

After the death of animals and plants, their components are recycled to be part of other beings, thus completing a cycle of life. For an organism to fossilize, special processes must occur that allow its preservation. When this type of situation occurs, then fossilization occurs.

Then, fossilization is the set of processes that make an organism, some of its parts or traces of its activity, become part of the fossil record.

When vegetables are printed in the sediment leaving their mark, as in this case where an image of a leaf is preserved, it is called "Impressions and Compressions." Then the tissue of the leaf degrades, leaving a trace of where the leaf once was. Finally, <u><em>as the leaf decomposes, the carbon of the leaf is left in the rock.</em></u>

A 14.1% by mass HClO3 solution has a density of 1.1690 g/mL. What is the concentration of this solution in molarity?
Scilla [17]

Answer:

[ HClO₃] = 1.93M

Explanation:

X % by mass, means that in 100 g of solution, we have X g of solute.

In this case, 14.1 g of HClO₃ are contained in 100 g of solution.

Density always referrs to solution. Let's calculate the volume of solution.

Solution density = Solution mass / Solution volume

1.1690 g/mL = 100 g / Solution volume

Solution volume = 100 g /1.1690 g/mL → 86.2 mL.

For molarity we must get moles of solute and volume of solution (L), because molarity is mol/L

Let's convert the mL of solution in L

86.2 mL . 1L / 1000mL = 0.0862 L

Now, let's determine the moles of solute. (Mass / Molar mass)

14.1 g / 84.45 g/mol = 0.167 moles

Molarity is mol/L →  0.167 moles / 0.0862 L = 1.93M

A 0.8115 g sample of HCl was placed into a 50 mL volumetric flask and the sample was thoroughly dissolved in water to make 50 mL
inysia [295]

Answer:

Molarity of NaOH solution is 1.009 M

Explanation:

Molar mass of HCl is 36.46 g/mol

Number moles = (mass)/(molar mass)

So, 0.8115 g of HCl = \frac{0.8115}{36.46}moles HCl = 0.02226 moles HCl

1 mol of NaOH neutralizes 1 mol of HCl.

So, if molarity of NaOH solution is S(M) then moles of NaOH required to reach endpoint is \frac{S\times 22.07}{1000}moles

So, \frac{S\times 22.07}{1000}=0.02226

or, S = 1.009

So, molarity of NaOH solution is 1.009 M
