Answer:
Percent yield = 65.2 %
Explanation:
The reaction determines this:
2 moles of Al react to 3 moles of chlorine gas in order to produce 2 mol of aluminum chloride.
We determine the moles of chlorine:
52 g . 1mol /70.9g = 0.733 moles of Cl₂
3 moles of gas can produce 2 moles of salt
Then, our 0.733 moles may produce (0.733 . 2) / 3 = 0.489 moles of AlCl₃
We convert moles to mass to predict the 100 % yield
0.489 mol . 133.3 g /mol = 65.19 g
Percent yield = (Yield produced / 100 % yield) . 100
Percent yield = (42.5 g / 65.19g) . 100 = 65.2 %
Answer:
46.784886 amu is the average atomic mass of titanium on that planet.
Explanation:
Fractional abundance of Ti-46 =72.000% = 0.72000
Atomic mass of Ti-46 = 45.95263 amu
Fractional abundance of Ti-48 =14.300% = 0.14300
Atomic mass of Ti-48 = 47.94795 amu
Fractional abundance of Ti-50 =13.700% = 0.13700
Atomic mass of Ti-50 = 49.94479 amu
Average atomic mass of titanium atom:
46.784886 amu is the average atomic mass of titanium on that planet.
<span>Condensation, Freezing and Precipitation.
The processes occur during water cycle that release energy are:
1) Condensation - Conversion of vapour into liquid
2) Freezing - Conversion of liquid into solid
3) Precipitation - Is basically a product of condensation, example drizzle, etc</span>
