Answer:

Pb(CO_{3})_{2} \\Pb(NO_{3})_{4} \\FeCO_{3}\\Fe(NO_{3})_{2}

Explanation:

Pb^{4+}(CO_{3}^{2-})_{2} --->Pb(CO_{3})_{2} \\Pb^{4+} (NO_{3}^{-})_{4} --->Pb(NO_{3})_{4} \\Fe^{2+} CO_{3}^{2-} --->FeCO_{3}\\Fe^{2+} (NO_{3}^{-})_{2}--->Fe(NO_{3})_{2}

Describe the nucleus of the atom. Include a description of its size relative to the rest of the atom.
faust18 [17]

Answer:

The nucleus is the most densely compacted part of the atom, it is in the center circled by the electron cloud or shells. It is filled with positively charged protons, and neutrons which have no charge. It is smaller than the electron cloud in size, but in quantity it has more subatomic particles since protons and electrons are equal and the nucleus has nuetrons

<u>Answer:</u> The correct option is C) 1.68 mol/L

<u>Explanation:</u>

Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L. The formula used to calculate molarity:

\text{Molarity of solution}=\frac{\text{Given mass of solute}}{\text{Molar mass of solute}\times \text{Volume of solution (L)}} .....(1)

Given values:

Given mass of C_6H_{12}O_6 = 150 g

Molar mass of C_6H_{12}O_6 = 180 g/mol

Volume of the solution = 0.50 L

Putting values in equation 1, we get:

\text{Molarity of solution}=\frac{150}{180\times 0.50}\\\\\text{Molarity of solution}=1.68M

Hence, the correct option is C) 1.68 mol/L

How can environmental science help you?​
alexandr402 [8]

Answer:

Organisms and humans depend on each other to get by. Environmental science is important because it enables you to understand how these relationships work.

For example, humans breathe out carbon dioxide, which plants need for photosynthesis. Plants, on the other hand, produce and release oxygen to the atmosphere, which humans need for respiration.

Animal droppings are sources of nutrients for plants and other microorganisms. Plants are sources of food for humans and animals. In short, organisms and humans depend on each other for survival.
