Consider each possible structure of carbon dioxide, c o 2. Determine whether the structure is correct and justify your decision.
1 answer:
This structure is correct due to the total number of bonds and electrons
We employ the octet rule, which states that all atoms in a compound are expected to follow, to check the accuracy of any chemical structure. The octet rule is precisely satisfied for each atom in the depicted structure of carbon IV oxide. The valence shell of each atom in the molecule is surrounded by eight electrons. We may thus infer that this structure is accurate given the total number of bonds and electrons since CO2 has sixteen valence electrons.
It possesses a negative charge of 1.602176634 coulombs, the basic unit of electric charge, which is comparable to its negative charge. The rest mass of an electron is 9.1093837015 10^-31 kg, or just 1/1,836 the mass of a proton. An electron is therefore considered to have practically negligible mass in comparison to a proton or neutron, and its matter is not taken into consideration when calculating an atom's mass number.

Answer: The percent yield of the reaction is 74 %
Explanation:
To calculate the number of moles, we use the equation:
.....(1)
For oxygen gas:
The chemical equation for the reaction of titanium and chlorine gas follows:
By Stoichiometry of the reaction:
4 moles of aluminium reacts with 3 moles of oxygen.
So, 0.092 moles of aluminium reacts with = of oxygen
As, given amount of oxygen is more than the required amount. So, it is considered as an excess reagent.
Thus, aluminium is considered as a limiting reagent because it limits the formation of product.
By Stoichiometry of the reaction:
4 moles of aluminium produce = 2 moles of
So, 0.092 moles of aluminium will produce = of
Now, calculating the mass of aluminium oxide:
To calculate the percentage yield of titanium (IV) chloride, we use the equation:
Experimental yield = 3.5 g
Theoretical yield = 4.7 g
Putting values in above equation, we get:
Hence, the percent yield of the reaction is 74 %
