As a result of the transfer of an electron from a less electronegative atom to a more electronegative atom,
1 answer:
<u>Answer:</u> The correct answer is Option d.
<u>Explanation:</u>
Electronegativity is defined as the tendency of an element to attract the shared pair of electron towards itself in a compound.
When electron is transferred from less electronegative atom to more electronegative atom.
The atom which is more electronegative gains electron and undergoes reduction reaction.
Reduction reaction is defined as the reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.
During the transfer of electrons, energy is released when an electron looses is potential energy during the transfer.
Hence, the correct answer is Option d.

Answer:
A. 3.2grams
Explanation:
First we need to get the chemical equation for this reaction:
CO + H₂ → CH₃OH
We then need to balance the equation:
CO + <u>2</u>H₂ → CH₃OH
Our next step is to first convert our given into moles. We do this by figuring out first how many grams of each substance there are in 1 mole by adding up the atomic mass of each element in each substance.
Carbon(1) Oxygen(1)
CO = 12.011(1) + 15.999(1) = 28.01 g/mole
Hydrogen(2)
H₂ = 1.008(2) = 2.016g/mole
We can then use this to determine how many moles of each reactant we have given the mass.
So here we have our new given:
0.1 moles of CO
0.496 moles of H₂
We then need to determine how much product we produce with our given.
According to our chemical equation we can assume that:
For every 1 mole of CO we can produce 1 mole of CH₃OH
Fore every 2 moles of H₂ we can produce 1 mole of CH₃OH
Using this ratio we can determine how much product each reactant will produce by using the ratios:
Now notice that they are not equal. The reactant that produces the least amount of product will be our limiting reactant. The limiting reactant determines the amount of product that is produced, because once it is completely used up, the reaction stops. So in this case, the amount of CH₃OH that is produced is 0.10 moles.
Now we need to figure out how many this is in grams. To do that we need to find out how many grams of CH₃OH there are in 1 mole of CH₃OH.
Carbon (1) Hydrogen(4) Oxygen(1)
CH₃OH = 12.001(1) + 1.008(4) + 15.999(1)
= 12.001 + 4.032 + 15.999 = 32.032g/mole
We then use this for converting:
So the reaction will produce 3.2032g of CH₃OH or 3.2g of CH₃OH
