Below is the answer. I hope it helps.
rate 1 / rate 2 = square root of M2/M1
<span>rate 238UF6 / 235UF6 = square root of [(Mass 235UF6) / (Mass 238UF6)] </span>
<span>rate 238UF6 / 235UF6 = square root of [(349.044) / (352.041)] </span>
<span>rate 238UF6 / 235UF6 = square root of [0.9914868] </span>
<span>Your answer: rate 238UF6 / 235UF6 = 0.9957343 </span>
<span>rate 235UF6 / 238UF6 = square root of [(352.041) / 349.044) ] </span>
<span>rate 235UF6 / 238UF6 = square root of [1.008586] </span>
<span>other answer: rate 235UF6 / 238UF6 = 1.004284 </span>
Answer: V = 6.30L
PV = nRT
15°C = 15+273 = 288K
3.75*V = 1.50*0.082057*288
V = (1.50*0.082057*288)/3.75
V = 6.30L

C) two or more elements that have been chemically combined
Answer:
last one
Explanation:
The elements classified as metalloids are boron, silicon, germanium, arsenic, antimony, tellurium, and polonium.
I found a similar question online which will help me answer your incomplete question. To make it easier, show all the elements of the compound given. It is shown in the second picture attached.
a.) The formula for unsaturation number is shown in the 3rd picture attached. Following this,
n = 8
m = 2(8) + 2 + 0 + 0 - 0 = 18
Thus,
x = Unsaturation number = (18 - 8)/2 = 5
<em>The unsaturation number is 5.</em>b.) The molar mass of C is 12.01 g/mol; H is 1 g/mol; O is 16 g/mol. So, the molecular weight is:
Molecular weight = 12.01(8) + 8(1) + 2(16) = 136.08 g/mol
<em>The molecular weight of the ester is 136.08 g/mol.</em>
