Answer:
9.8g
Explanation:
Using periodic table find molar mass of C and H:
C=12.01g/mol
H=1.008g/mol
Molar mass of C2H4=(12.01)2+(1.008)4=28.03g/mol
Using molar mass times moles of the chemical to find the mass in 0.35 moles of c2h4:
28.03 x 0.35=9.8grams
<u>Answer:</u> The number of formula units present in 2 moles of 
are 
<u>Explanation:</u>
Formula units are defined as the number of molecules or atoms present in 1 mole of a compound or element respectively.
According to mole concept:
1 mole of a compound contains 
number of formula units
Here, 2 represents the number of moles of
We are given:
Moles of (glucose) = 2 moles
Number of formula units of 
Hence, the number of formula units present in 2 moles of are
4Ag + 2H2S + O2 -> 2Ag2S + 2H20 i’m pretty sure that’s correct
Answer:
Cellular respiration
Explanation:
Fermentation is a mechanism in anaerobic respiration(breaking down glucose in the absence of oxygen). Examples are lactic acid fermentation is humans, Alcohol fermentation in yeast.
Cellular respiration sums up both anaerobic and aerobic(with oxygen)
Metabolism is just breaking down food molecules chemically into their simplest forms (monomers). These monomers then undergo cellular respiration to produce ATP
Answer:
Its existence was determined by an English scientist studying nature.
Its existence was established after the invention of the microscope.
Explanation:
I know because atoms are made up by a scientist study chemicals while trying to learn about atoms as well.
