Answer:
The Big Bang Theory is the leading explanation about how the universe began. At its simplest, it says the universe as we know it started with a small singularity, then inflated over the next 13.8 billion years to the cosmos that we know today
Explanation: According to the standard Big Bang model, the universe was born during a period of inflation that began about 13.8 billion years ago. Like a rapidly expanding balloon, it swelled from a size smaller than an electron to nearly its current size within a tiny fraction of a second.
Answer: I’m sorry if I’m wrong but I think the answer would be a) 3-menthylbutane. Again, if I’m wrong I am very sorry. Hope this helps❤️
Theoretical
yield is the amount supposedly produced by the reaction if it was complete. The
balanced chemical reaction is:<span>
</span>
<span> C2H6 + Cl2 = C2H5Cl + HCl</span>
<span>
We use the amounts given for the reactants as
the starting point of the calculations to determine the limiting reactant. We do as follows:
150 g C2H6 ( 1 mol / 30.08 g
) = 4.987 mol
205 g Cl2 ( 1 mol / 70.9 g ) = 2.891 mol
Therefore, the limiting reactant would be Cl2 since it would be consumed completely first in the reaction.
We use this for the theoretical yield.
<span>2.891 mol Cl2 ( 1 mol C2H5Cl / 1 mol Cl2 ) = </span>2.891 mol C2H5Cl (THEORETICAL YIELD)
172 g ( 1 mol / 64.52 g ) = 2.666 mol C2H5Cl (
ACTUAL YIELD)
Percent yield = 2.666 / 2.891 x 100 = 92.21%</span>
