Explanation:
Rock cycle(Attachment-1)
The rock cycle and plate tectonics cause Earth's rocks to break down over time and they are recycled through natural processes is the best answer.
What are rock cycle?The rock cycle is defined as the process through which the three main rock types i.e. igneous, metamorphic and sedimentary rock transfer from one type to another type.
The plate tectonics is defined as a theory that earth's outer shell is divided into large slabs of solid rocks known as "plates" that glide over earth mantle, the rocky inner layer above earth's core.
Thus, the rock cycle and plate tectonics cause Earth's rocks to break down over time and they are recycled through natural processes is the best answer.

You have 150.0 mL of a 0.415 M solution of Ce(NO₃)₄.
a) What mass (in grams) of Ce(NO₃)₄ would be required to make the solution?
B) What is the concentration of the nitrate ions in the solution ?
C) If the original solution was diluted to 350.0 mL, what would be the new concentration of the Ce(NO₃)₄ in the solution?
Answers
A. The mass (in grams) of Ce(NO₃)₄ that will be required to make the solution is 24.16 g
B. The concentration of the nitrate ions in the solution is 1.66 M
C. The new concentration of the Ce(NO₃)₄ solution is 0.178 M
We'll begin by calculating the number of mole of Ce(NO₃)₄ in the solution.
Molarity = 0.415 M
Volume = 150 mL = 150 /1000 = 0.15 L
Mole of Ce(NO₃)₄ =?Mole = Molarity × Volume
Mole of Ce(NO₃)₄ = 0.415 × 0.15
Mole of Ce(NO₃)₄ = 0.06225 moleA. Determination of the mass of Ce(NO₃)₄ required to make the solution.
Mole of Ce(NO₃)₄ = 0.06225 mole
Molar of Ce(NO₃)₄ = 140.12 + 4[14 + (16×3)]
= 140.12 + 4[14 + 48]
= 140.12 + 4[62]
= 140.12 + 248
= 388.12 g/mol
Mass of Ce(NO₃)₄ =?Mass = mole × molar mass
Mass of Ce(NO₃)₄ = 0.06225 × 388.12
Mass of Ce(NO₃)₄ = 24.16 gTherefore, 24.16 g of Ce(NO₃)₄ is required to make the solution.
B. Determination of the concentration of the nitrate ion, NO₃¯ in the solution.
In solution, Ce(NO₃)₄ will dissociate as follow:
Ce(NO₃)₄ (aq) —> Ce⁴⁺(aq) + 4NO₃¯(aq)
From the balanced equation above,
1 mole of Ce(NO₃)₄ contains 4 moles of NO₃¯
Therefore,
0.415 M solution of Ce(NO₃)₄ will contain = 0.415 × 4 = 1.66 M NO₃¯
Thus, 1.66 M of the nitrate ion, NO₃¯, is present in the solution.
C. Determination of the new concentration of the Ce(NO₃)₄ solution.
Volume of stock solution (V₁) = 150 mL
Molarity of stock solution (M₁) = 0.415 M
Volume of diluted solution (V₂) = 350 mL
Molarity of diluted solution (M₂) =?
M₁V₁ = M₂V₂0.415 × 150 = M₂ × 350
62.25 = M₂ × 350
Divide both side by 350
M₂ = 62.25 / 350
M₂ = 0.178 MTherefore, the new concentration of the Ce(NO₃)₄ solution is 0.178 M

A 200.0 ml beaker filled with oil has a mass of 293.2 g. The mass of just the beaker is 130.2

Answer in a complete sentence. Show your work. Your final answer should have the cor-
rect number of sig figs. show work!
Answers
Answer:p=m/v
p=(292.2-130.2)/200
p=0.8100g/ml
Explanation:
Density of a substance is the ratio of its mass to volume. The density of the oil filled in a 200.01 ml beaker is 0.815 g/ml.
What is density?Density of a substance is the mass per volume. Thus we het how much of its particles are located per one unit of volume.
Mathematically density can be written as mass/ volume. The mass of the beaker containing oil is given as 293.2 g. The mass of beaker itself is 130.2 g. Hence, mass of oil is 293.2 - 130.2 = 163 g.
Volume of the oil is 200 ml. Thus density is 163 g/200 ml = 0.815 g/ml.
Hence, the oil in the beaker with 200 ml volume and 163 g mass have a density of 0.815 g/ml.

calculate the boiling point elevation for solution of 25.0 grams of menthol in 130 grams of ethanol. Ethanol boiling point elevation constant is 1.22 oC/m
Answers
Answer:
Explanation:
When a solute is added to a solvent, the vapor pressure of the solvent (above the resulting solution) is less than the vapor pressure above the pure solvent. The boiling point of a solution, then, will be greater than the boiling point of the pure solvent because the solution (which has a lower vapor pressure) will need to be heated to a higher temperature in order for the vapor pressure to become equal to the external pressure (i.e., the boiling point).
The boiling point of the solvent above a solution changes as the concentration of the solute in the solution changes (but it does not depend on the identity of either the solvent or the solute(s) particles (kind, size or charge) in the solution).

A reaction occurs that results in a molecule with two atoms of the same element. The atoms share six electrons. Which molecule could be the product of the reaction?
Si2

Answers
Answer:
n2 is correct
Explanation:
i took it just now. :)
The product of this reaction could be N2.
Among the options, only atoms of nitrogen have five electrons on their outermost shell.
The fact that they have five electrons in their outermost shells implies that they can combine by sharing six electrons in a triple bond.
When this occurs, each of the nitrogen atoms involved in the bond now has an octet of electrons. Hence, the product formed when the atoms share six electrons. Which molecule could be the product of the reaction is N2.
