When the calcium atom loses electrons, it's charge increases by the number of electrons lost.
It loses 2 electrons, so it's charge increases by 2.
The answer is +2
Answer:
both apply
Step-by-step explanation:
i guessed just do it
Where are the answer choices?
but the answer either way has to be:
v = d/t . v is velocity, d is for distance, and t is for time
Answer:
S'(5,-1), M'(1,-3)
Step-by-step explanation:
So, if the rotation is clockwise, the formula is (x,y)--->(-x,-y).
The original points are, (-1,3) and (-5,1).
Using the formula,
(-1,3) ----> (1,-3)
(-5,1) ----> (5,-1)
For the question in the image, the reflection over the x-axis is..
S'(-5,1) ---> (-5,-1)
M'(1,-3) ---> (-1,-3)
