A. good conductors is not a characteristic of metals out of all the other followings.
D) If only 6.6 grams of water are produced, what is the percent yield?
Write out the balanced equation:
2C2H6 + 7O2 --> 4CO2 + 6H2O
Then, determine the limiting reagents:
16.8 grams of C2H6/30.06 g/mol of C2H6 = 0.46 mol
45.8 grams of O2/32 g/mol of O2 = 1.4 mol
0.46 mol of C2H6/2 = 0.23
1.4 mol of O2/7 = 0.20
<em>- Dioxygen is the limiting reagent. </em>
Find the theoretical molar yield of water:
There is a 7 mol of O2 to 6 mol of H2O ratio (according to the balanced equation).
<em>We can setup a proportion;</em>
7/6 = 0.23/x
0.196 = x
So, 0.196 mol of water will be produced.
How many grams of water will be produced in the reaction?
<em><u>0.196 mol of H2O x 18 g/mol of H2O = 3.53 grams of H2O </u></em>
Hydroxychloroquine cannot be made from grapefruit and lemon rinds.
Hydroxychloroquine is not a natural compound, rather it can only be synthesized from quinoline molecule in the laboratories.
During the synthesis of hydroxychloroquine, several sequential chemical reactions and purifications are done.
Hydroxychloroquine is used in the treatment of:
- malaria
- systemic lupus erythematosus,
- rheumatoid arthritis
But when grapefruit and lemon rinds are boiled in water, a natural chemical compound known as limonene is obtained.
Therefore, hydroxychloroquine cannot be made from grapefruit and lemon rinds,

Answer:
The mass of 2.0 mol of C02 is 44 grams
Explanation:
The weight of CO2 is 44 grams per mole (1 x 12 grams/mole for the carbon and 2 x 16 grams/mole for the oxygen atoms)
