The balanced equation for the above reaction is;
2K + Cl₂ ---> 2KCl
Stoichiomtery of K to KCl is 2:2
Potassium is the limiting reactant which is fully consumed in the reaction. The amount of product formed depends on amount of limits reactant present.
Number of moles of K reacted - 6.75 g/ 39 g/mol = 0.17 mol
Therefore number of KCl moles formed - 0.17 mol
Mass of KCl formed - 0.17 mol x 74.5 g/mol = 12.67 g

Suppose a scientist proposes a plan to destroy all bacteria on Earth in order to get rid of diseases caused by bacteria. Explain
dimulka [17.4K]
This would not be a good idea because bacteria is everywhere and function as a part of out everyday lives. Starting off with animals, many animals rely on bacteria to digest their food so many animals would begin to die off. Ecosystems would fail due to nitrogen not being able to cycle.
Without bacteria biological waste would build up causing a drop in population, eventually going extinct.
Basically, the balance of nature between humans, animals, and plants would no longer exist.
