Based on the ion structure, which of the following elements would form a bond with calcium in a one to one ratio and why?
O A. One bromine ion would bond to one calcium ion because the combination of their charges would result
in a full octet.
OB. One bromine ion would bond to one calcium ion because they are both located on period 4.
C. One selenium ion would bond to one calcium ion because they are both located on period 4.
D. One selenium ion would bond to one calcium ion because the combination of their charges would result
in a full octet.

the answer is true.

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.

explanation:

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
