K means "okay" KK is also another way of saying it.
According to the reaction (4 \text{K} + \text{O}_2 \rightarrow 2 \text{K}_2\text{O}), 4 moles of potassium produce 2 moles of potassium oxide (K2O). Thus, the mole ratio of potassium to K2O is 4:2, or 2:1. If 1.52 moles of potassium are used, the number of moles of K2O formed can be calculated as (1.52 , \text{moles K} \times \frac{2 , \text{moles K2O}}{4 , \text{moles K}} = 0.76 , \text{moles K2O}). Therefore, 0.76 moles of potassium oxide will be formed.
I believe you mean obfusticated or scrambled text in which case you must paste in §k before the text and §r after. Try it in a book to see if it's what you mean.
