Answer:
Step-by-step explanation:
11
n-30=14-3n
you add 3n to both sides
then you'll have 4n-30=14
you add 30 to 14
4n=44
n=11
Given:
Two electrons are added to each of six atoms in a group.
To find:
The expression for the net change in charge.
Solution:
Charge of atoms = Number protons - Number of electrons.
Let number of atoms be x.
6 atoms = 2 electrons added
1 atom = electrons added
1 atom = electrons added
x atoms = electrons added
Therefore, the net change in charge is represented by the expression because we subtract number of electrons to find atom charge, where, x is the number of atoms.
6 atoms = 2 protons removed
1 atom = protons removed
1 atom = protons removed
x atoms = protons removed
Therefore, the net change in charge is represented by the expression , where, x is the number of atoms.
Answer:
Step-by-step explanation:
(0, 1) (4, -2)
(-2 - 1)/(4 - 0)= -3/4
answer is B.
The answer is b 4(a-p), difference implies subtraction
