The answer is <span>a. Rubidium
A cation is an ion that has a positive charge. The charge positive because it loses electrons. The radius of an atom is influenced by the electron because it is found at the outer layer of the atom. Since cation has less electron and anion get more electron, the radius of cation will be smaller than anion.
Rubidium is the biggest cation because it is located in the lowest row, thus having most electron count.</span>
Answer:
1.04 tonnes
Explanation:
As we have the equation balanced, we need to know, form the percent yield and the theoretical yield, the actual yield:
With this, we need to convert the mass of sucrose into moles:
Now, with the yield, we apply the rule of three, with the actual yield, to know the moles of citric acid produced:
Therefore, 5392.93 moles of citric acid are produced, now we need to know the mass:
7,040 energy to freeze the silver :)
