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.

Yeah so you have to start of with converting your first two values into moles (forget the third one)
97.5 g NO * 1 mol/30.01 g NO = 3.25 moles NO
88.0 g O2 * 1 mol/16.00 g O2 = 5.5 moles O2
now we can find the limiting reactant by checking for the amount of product each reactant should give us by using molar ratios
3.25 mol NO * 2 mol NO2/2 mol NO = 3.25 mol NO2
5.5 mol O2 * 2 mol NO2/ 1 mol O2 = 11
so NO is the limiting reactant since it produces less product/gets used up quicker
3.25 mol NO * 2 mol NO2/2molNO = 3.25 mol NO2
so this is our theoretical yield and the question provides us with the actual yield (2.68 moles). since the actual yield is given in moles, we don't have to convert to grams. our percent yield formula goes like: actual yield/theoretical yield * 100
2.68 mol/3.25 mol * 100 = 82.46%
Answer:
gold is metal which is a very good conductor for electric current and most chips are made out of it.
