The answer is "Option B"
Explanation:
From the query, the following knowledge is derived:
Yield in percentage = 47%
Performance of theory = 4860 g
Actual yield Rate =?
The percentage return is defined simply by the ratio between both the real return as well as the conceptual return multiplied by the 100. It's also represented as numerically:
Now We can obtain the percent yield as followed using the above formula:
The value of the Actual yield Rate =
The Actual yield Rate= 2284.2 g.
In the modern periodic table, the elements are arranged according to their atomic number - not their relative atomic mass.
In the periodic table the elements are arranged into:
rows, called periods, in order of increasing atomic number
vertical columns, called groups, where the elements have similar properties
