Answer:
79.14%
Explanation:
Given the equation : 2Fe2O3 + 3C 4Fe + 3C02
The theoretical yield of CO2 ; is 102.6g
Actual yield = 81.2 gram
Percentage yield = (actual yield / theoretical yield) * 100%
Percentage yield = (81.2 / 102.6) * 100%
Percentage yield = 0.7914230 * 100%
Percentage yield = 79.14%
Hence, tbe percentage yield of CO2 is 79.14%
Answer:
Sulfur is NOT a metal.
Explanation:
Out of all the options the one that is NOT a metal is s. Sulphur has characteristics of nonmetals. It does not have luster, it cannot conduct electricity, and it is brittle. On the periodic table, sulphur is in group 16/VIA, in the third period.
In areas where resistance is present, otherantimalarials<span>, such as </span>mefloquine<span> or atovaquone, may be used instead. The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations.</span>
a) Number of protons = number of electron in the atom = atomic number
So it has 7 protons answer
N-3 has gained 3 electron so number of electrons + 7+3
= 10 answer
Answer:
The solubility of gases decreases with pressure as that of solids and liquids is not affected.
