Answer:
³₂He
Explanation:
From the question given above, the following equation was obtained
²₁H + ²₁H —> ¹₀n + __
Let ᵇₐX be the missing part of the equation. Thus, the equation becomes:
²₁H + ²₁H —> ¹₀n + ᵇₐX
Next, we shall determine b, a, and X. This can be obtained as follow:
2 + 2 = 1 + b
4 = 1 + b
Collect like terms
b = 4 – 1
b = 3
1 + 1 = 0 + a
2 = 0 + a
a = 2
ᵇₐX => ³₂X => ³₂He
Thus the equation is:
²₁H + ²₁H —> ¹₀n + ᵇₐX
²₁H + ²₁H —> ¹₀n + ³₂He
The missing part is ³₂He
Answer:
The radius of the centrifuge.
Explanation:
Hello,
Since the radius of the centrifuge is just a design parameter, it wouldn't be a cause of failure because it is used to know how many tubes could be fitted in into the centrifuge. On the other hand, keeping you attention away from other factors could turn into a failure as long as the sample could be poured down or just turn out inadequate for the expected results.
Best regards.
Process energy required
1) raise the temperature to 75.0 °C 628 J
2) evaporate the liquid at 75.0°C 15.6 KJ = 15,600 J
3) raise the temperature to ? 712 J
Total energy: 628 J + 15,600 J + 712 J = 16,940 J
As you must have realized the clue to do the problem correctly is to convert all the energy values to joules, because you cant not add up joules with kilo joules.
Answer: 16,940 J
