The correct answer is - Jerusalem
False
if the pH is 8, this is basic because based on the pH scale, any below 7 is acidic, above 7 is basic and at 7 is neutral.
Methanol(CH3OH) is a nonelectrolyte as it is not readily ionized when melted and dissolved, and a poor conductor of electricity when it is in solution.
Nanelectrolyte Contains covalent bonds and typically nonpolar molecules. Methanol doesn't dissolve in water, as the H of the alcohol functional group is not acidic enough so we can't easily separate it from the molecule.
Answer:
Theoretical yield for Si = 2586.55*28.09= 72.7 Kg
Percentage yield is =2356.71/2586.55=91.11%
Explanation:
So the chemical equation for this reaction would be SiO2 + 2C = Si + CO
so n(SiO2)=m(SiO2)/M(SiO2)=155400/60.08=2586.55 mol
n(C)=m(C)/M(C)=77400/12.01=6444.63 mol
So Carbon is in exes.
n(Si)=m(Si)/M(Si)=66200/28.09= 2356.71 mol
Theoretical yield for Si = 2586.55*28.09= 72.7 Kg
Percentage yield is =2356.71/2586.55=91.11%
You can reduce our carbon footprints by using renewable energy,calculate your carbon footprint and make changes,use car less and minimize driving and walk or cycle more and reduce water use.
Hydrogen fuel can not replace fossil fuels this is because fossil fuel use more energy and make more pollution.
