How many zero pairs can be created in the model below?

3

Step-by-step explanation:

Zero pairs are +/- pairs which add to 0. They are inverse of each other.

+x and -x

+1 and -1

+1 and -1

There are 3 zero pairs in the above model.

Step-by-step explanation:

Given the model we have to tell the number of zero pairs can be created in the model.

As the zero pairs are +/- i.e the result we get 0

The zero pairs in the above model are

x/-x

+/-

+/-

Hence, there are 3 zero pairs in the above model.

the answer is b.)

< 1=< 2
