calculate the net charge on a substance consisting of a combination of 3.0X10^13 protons and 8.6X10^13 electrons.
What is (8.6-3.0)E13*chargeperelectron?
The number of electrons is greater than the number of protons, therefore,
the net charge is negative:
(8.6-3) •10613•(-1.6•10^-19)=
= - 8.97•10-6 C
To calculate the net charge on a substance, you need to find the difference between the total positive charge (protons) and the total negative charge (electrons).
Given:
Number of protons = 3.0 x 10^13
Number of electrons = 8.6 x 10^13
The charge on each proton is +1, and the charge on each electron is -1.
Step 1: Calculate the total positive charge:
Total positive charge = Number of protons x charge per proton
Total positive charge = (3.0 x 10^13) x (+1)
Step 2: Calculate the total negative charge:
Total negative charge = Number of electrons x charge per electron
Total negative charge = (8.6 x 10^13) x (-1)
Step 3: Calculate the net charge:
Net charge = Total positive charge + Total negative charge
Substituting the values we calculated:
Net charge = (3.0 x 10^13) x (+1) + (8.6 x 10^13) x (-1)
Now, let's calculate the net charge:
Net charge = 3.0 x 10^13 - 8.6 x 10^13
Net charge = -5.6 x 10^13
Therefore, the net charge on the substance is -5.6 x 10^13.
To calculate the net charge on a substance, you need to find the difference between the total number of protons and the total number of electrons. The charge of a proton is +1 elementary charge (e), and the charge of an electron is -1 elementary charge.
Given that there are 3.0 x 10^13 protons and 8.6 x 10^13 electrons, you can use the following equation:
Net Charge = (Number of Protons) x (Charge of Proton) + (Number of Electrons) x (Charge of Electron)
Net Charge = (3.0 x 10^13) x (+1 e) + (8.6 x 10^13) x (-1 e)
Simplifying the equation:
Net Charge = 3.0 x 10^13 e - 8.6 x 10^13 e
Net Charge = -5.6 x 10^13 e
Therefore, the net charge on the substance is -5.6 x 10^13 elementary charges (e).
