If they have 3 chemistry classes with 24 students, than there are 72 students in total. Each student requires 4 test tubes. 72 * 4 = 288 test tubes. Our answer is C.) 288 test tubes
Answer:
Option C, (Actual yield ÷ percent yield) × 100
Explanation:
Theoretical yield is defined as the total amount of product formed for given reactants in a chemical reaction. It is an ideal case which assumes no exceptions or wastage.
The mathematical relation between the actual yield, percent yield and theoretical yield is as follows -
Where
P.Y. represents the percent yield a
M A.Y. represents the mass obtained from actual yield
M T.Y. represents the mass obtained from theoretical yield
Hence, if we rearrange the formula, we get -
Hence, option C is correct
Fusion releases less energy than fission
fusion most commonly combines heavy isotopes of hydrogen into helium.
Explanation:
Nuclear fusion is a form of reaction that involves the combination of two light nuclei to form one that is heavier in mass.
The other form is nuclear fission which is the splitting of heavier nuclei either spontaneously or when bombarded with other nuclei.
- Nuclear fusion reactions in the core of stars powers the universe.
- The reactions produces a huge amount of energy of a greater and massive order than fission reaction.
- Small nuclei are involved in nuclear fusion and not the large ones.
- Nuclear fusion degenerates into series of chain reactions that are extremely difficult to control.
