Answer: It is very important to know the activity tendencies of the elements. The activity tendencies tells us about whether the element is reactive or not.
In the redox-reaction where there is a need to know the oxidizing agent and reducing agent, we can know it easily from the activity tendencies. The elements lying above the reactivity series are better reducing agents.
In the substitution reactions, the activity tendencies helps us to know which element will replace the other. The element lying above in the series will replace the element lying below it.
where, N is an element that lies above in the reactivity series
M is an element that lies below in the reactivity series
The amount of Ca is not limiting, we have : 2.87g of O will produce : 2.87 / 56.1 = 0,051158645 mol of CaO
What is Mass?
Mass is a property that represents the amount of matter in a sample. Mass is often expressed in grams (g) and kilograms (kg) (kg). Mass can alternatively be defined as the property of matter that provides it the ability to resist acceleration. The more mass an object has, the more difficult it is to accelerate.
