It's likely what's wanted is
<span><span>Li</span>→<span><span>Li</span><span>2+</span></span>+2<span>e−

The reason is because IEs are usually reported from the neutral atom, that is, IE2 is the energy required to remove two electrons from a neutral Li atom, as above, rather than the additional energy required to remove one more electron from an Li+ cation.
Answer:
B. pour the reagent into a small beaker before using it
Explanation:
Let's explore all the mentioned practice
A. Leftover reagents should not be discarded in the sink but discarded according to the disposal method present in the safety data sheet (SDS) of the chemical.
B. Reagents should be poured in a clean beaker for use to avoid contamination in the original reagent bottle
C. This is not a good practice, as the plastic pipet tends to contain some impurity in its tip.
D. This is also a bad practice. Firstly, a reagent should be taken according to the need. If there is leftover, it should be discarded as it most probably contains contamination in it

Answer:
See explanation
Explanation:
Average heart beat = Number of heart beats/ time
7.0 years = 7.0 * 365 * 24 * 60 = 3679200 minutes
If there are 69 beats in 1 minutes
There are x beats in 3679200 minutes
x = 253865 beats
x = 254000.00 beats ( to 3 sf)
beats in 7.00 years = 254000.000 beats
beats in 7.000 years = 254000.0000 beats
