The equation is as follows;
2CH3OH(g) = 2CH4(g) + O2(g), ΔH= +252.8 kJ
From the equation; for the reaction to produce 2 moles of methane (32g) an energy of 252.8 kJ is released.
Therefore; for an energy of 82.3 kJ the number of moles that will be produced will be; = (2×82.3)/252.3
= 0.6524 moles
which is equivalent to 0.6524 × 16 = 10.438 g
There, the mass of CH4 produced will be 10.438 g
The products are on the right side of the chemical equation, while the reactants are on the left side of the chemical equation.
Therefore if we have:
methane + oxygen → carbon dioxide + water
Then the reactants are methane + oxygen
The products are: A) Carbon dioxide + Water
Answer:
Which best describes the geologic time scale? It explains why events happen throughout Earth’s history. It presents the correct sequence of events in Earth’s history. It is used to determine the absolute dates in years for different periods.
Answer:
Multiple fractionation occurs when each tray in the tower has liquid of different weights and temperatures
Answer:
If the amount of magnification is correct, then an individual germ can be seen, because individual germs exist but are too small for human eyes.
Explanation:
<em>Leeuwenhoek was the first scientists to experiment with microorganisms using a self-designed single-lens microscope. He described the tiny organisms as 'animacules'. He is known for his pioneer work in the design of the first microscope.</em>
The microscope works by magnifying objects placed on the stage. Germs are microbes that cannot be seen with ordinary eye unless they are magnified appropriately. They are virtually everywhere, including the parts of the world where humans cannot survive.
Hence, the only correct option which most likely inspired Leeuwenhoek's experimentation with technology is the first option. The remaining options are deficient in some ways.
