Explanation:
Answer:
2.60 moles of A remaining.
Explanation:
According to Le Chatelier's principle, the equilibrium would shift if the volume, concentration, pressure, or temperature changes.
In this question, we were told that the volume doubles, that implies that we would have to double the molarity of B/ C (since B=C.)
However, it is obvious and clear from the given equation of the reaction that A is solid in it's activity = 1. Hence, it is then ignored.
So doubling B would be 1.30 M × 2 = 2.60 M
i.e 2.60 M moles of A was consumed.
Now; the number of moles of A remaining is 5.20 - 2.60 = 2.60 moles of A remaining.
Answer:
In direct observation, EVERY INDIVIDUAL in a population is counted. In indirect observation, SIGNS OF AN INDIVIDUAL, such as tracks or nests, are counted.
Explanation:
Direct observation is to involve looking at the actual behavior or occurrence so for your question it would be every individual.
Indirect observation is a result of that occurrence, so for your question it would be the signs of an individual.
