True
Explanation:
Dispensing chemical from large stock bottles into smaller container makes sure that students only takes the quantity they need which reduces wastage. Also in situation where the students did not finish the reagent or chemical it is easier for student to pour back into smaller bottle than the entire reagent bottle which can contaminate the whole solution. Small bottles prevent or reduces the risk of spillage because it is easier to handle and pour.
Answer:
Explanation:
If it is at a higher energy level, it is said to be excited, or any electrons that have higher energy than the ground state are excited. They are then called degenerate energy levels.
In the given reaction, B + KL + H, the effect of adding further B is that it favors the forward reaction which means more products will be produced upon the addition. This obeys Le Chatelier's principle which <span>states that any disturbance incurred to the equilibrium system
shall be dealt such that the disturbance is countered to and attain equilibrium
again.</span>
It's a chemical change beacause elements are combining to make something new! :)
