C. Weathering, plate movements and volcanoes destroyed many of

the craters

Explanation:

The earth is a dynamic planet. Both external and internal processes sculpt and shapes the surface and interior of the earth primarily from the energy from the sun and the primordial heat accumulated during the formation of the earth.

  • The period of heavy bombardment of the earth resulted in the creation of craters and other impact features on the earth surface.
  • As earth evolved, the process of weathering which is one of the tools of denudation caused the lowering and changing of the earth. Through this process sedimentary rocks were formed.
  • The movement of the earth through plate tectonics also greatly shaped the earth. New materials from the interior were brought to the surface. Some existing parts were destroyed at subduction zones. Some also became elevated.
  • Volcanism also brought new materials to the surface and this changed the terrain.

A hypothetical element x has 3 naturally occurring isotopes: 41.20% of 21x, with an atomic weight of 21.016 amu, 50.12% of 22x,
iogann1982 [59]
The average atomic weight is calculated by adding up the products of the percentage abundance and atomic weight. In this item, we have the equation,

     A = (0.412)(21.016 amu) + (0.5012)(21.942 amu) + (0.0868)(23.974 amu)

Simplifying the operation will give us the answer of 21.74 amu.

<em>Answer: 21.74 amu</em>

Identify the mole ratio of water to sodium metal? Determine the number of moles of Sodium that reacted and determine the number
frozen [14]

Number of moles of sodium reacted is 2 moles. 0.04598 Kg is the mass of sodium that reacted.

Mole fraction is 1 mole ratio is 1:1

Explanation:

Balanced chemical reaction:

2 Na + 2H20 ⇒ 2NaOH + H2 (gas)

atomic mass of sodium = 22.99 g/mol

from the reaction it can be seen that 2 moles of sodium reacted to form 2 moles of sodium hydroxide soluition.

The mass of sodium reacted can be calculated from the formula:

mass = atomic mass of one mole x number of moles

mass = 22.99 x 2

         = 45.98 grams is the mass of sodium, to convert it into kilograms it is divided by 1000

= 0.04598 Kg is the mass of sodium that reacted.

Mole fraction formula is:

\frac{moles of solute}{moles of solution} = mole fraction   ( solute Na = 2 moles, solution is NaOH =2 moles)

putting the values:

\frac{2}{2}

= 1 mole ratio is 1:1
