Question

Match the number of negative charges to the number of positive charges to make each combination balanced.

a) 1 negative charge - 1 positive charge
b) 3 negative charges - 2 positive charges
c) 2 negative charges - 3 positive charges
d) Balancing is not possible with the given charges.

Answer 1

To balance the combination of charges, the number of negative charges should match the number of positive charges. Only combination a) is balanced.

Step-by-step explanation:

To balance the combination of charges, the number of negative charges should match the number of positive charges. Let's analyze each combination:

• a) 1 negative charge - 1 positive charge: This combination is balanced because the number of negative charges is equal to the number of positive charges.
• b) 3 negative charges - 2 positive charges: This combination is not balanced because the number of negative charges is greater than the number of positive charges.
• c) 2 negative charges - 3 positive charges: This combination is not balanced because the number of negative charges is less than the number of positive charges.
• d) Balancing is not possible with the given charges: This combination is not balanced because the number of negative charges does not match with the number of positive charges.

Therefore, only combination a) is balanced.
