The decomposition of potassium chlorate produces oxygen gas according to the reaction: 2 KClO3 —-> 2 KCl +3 O2 When 38.5 g of potassium chlorate is heated, 10.0L of oxygen gas is produced at STP. What is the percent yield of this reaction?

The independent variable is the type of music.the dependent variable is the pulse rate.the intervening variable is the age of the subject.if the mother does not like rock, her pulse is likely to not increase.the same might be true for the sister.the friend may like rap and gets excited.to establish cause/effect relationship, all of the subjects must be consistent.hope i .

Neither model is able to show the reactivity of potassium.

A. ​it generates energy from carbohydrates.b. it requires activation by oxygen.​c. ​it is used by cells to dispose of excess electrons
