The balanced chemical equation of the reaction described above is,
C2H6O + O2 --> H2O + C2H4O2
If we have 3.84 g of oxygen, we divide by its molar mass.
n = (3.54 g Oxygen gas) x (1 mole O2/ 32 g O2)
n = 0.11 moles O2
Using ratio and proportion,
number of moles of ethanol = (0.11 moles O2) x (1 mole C2H6)
= 0.11 moles C2H6
Then, we multiply the calculated value to its molar mass, 46 grams /mol.
mass of ethanol = (0.11 mol) x (46 grams / mol)
= <em>5.06 grams</em>
Answer:
a. Thermal energy in transit due to spatial temperature difference .
Explanation:
Heat transfer -
Heat transfer is the exchange of the thermal energy or heat in between any physical systems .
It is the flow of energy or any form of energy from one system to another .
Heat transfer is divided into various mechanism , one of which is the thermal .
The thermal energy is the transit due to the spacial temperature difference .

Hope this answers your question <3
Explanation:
CRISPR technology is a simple yet powerful tool for editing genomes. It allows researchers to easily alter DNA sequences and modify gene function. They do so primarily by chopping up and destroying the DNA of a foreign invader.
