Answer:
ionic charge
Step-by-step explanation:
So, an atom with an ionic charge of +2 has two more protons than electrons. The element calcium, for example, has atomic number 20 so the atom has 20 protons. The calcium ion with a positive +2 charge has two more protons than electrons.
Answer:
Any values for n that are greater than 4 will satisfy the expression
Step-by-step explanation:
We have the expression
7n/4 > 7 solve for n...
7n > 28 multiply by 4 on both sides
n > 4 divide by 7 on both sides,
n is greater than 4, so any value for n greater than 4 will satisfy the inequality
Subtract 24 to 78. Divide the answer by 24. Multiply it by 100. So the final answer is 225%.
We have a starting value of 24. In order to reach 78, we need to multiply a number to 24 and add it to 24.
Making the equation 24 + 24P = 78.
Transpose 24 to the other side, you’ll get 24P = 78--24.
24P=54.
Divide both sides by 24, you’ll get P = 2.25
Multiply 2.25 by 100 to get the percentage.
So, you’ll get the final answer 225%
