Answer:
B) The cold air moves faster and pushes the warm air away, causing condensation and rain.
Solar Power, Microbial fuel cell. These two and I am sure other ways as well Solar power as you guess use the sun as a power energy source with non-waste and long lasting use. Microbial fuel uses the bacteria aka decomposers turn the sugars, nutrients into rich soil while also releasing electrons back into the soil and can be used as a energy source.
Answer:
The formula of Quartz is SiO2. So, 1 mole of Quartz will have 2 moles of oxygen atoms, i.e. 2 x 6.022 x 10^23 atoms of oxygen. The molar mass of quartz is 60 g per mol. So, 60 g quartz means 1 mole quartz.

Answer:
0.106 mol (3s.f.)
Explanation:
To find the number of moles, divide the mass of glucose (in grams) by its Mr. Glucose has a chemical formula of C6H12O6. To find the Mr, add all the Ar of all the atoms in C6H12O6.
Ar of C= 12, Ar of H= 1, Mr of O= 16
These Ar values can be found on the periodic table.
Mr of glucose= 6(12)+ 12(1) + 6(16)= 180
Moles of glucose
= mass ÷ mr
= 19.1 ÷ 180
= 0.106 mol (3 s.f.)
