HI, I need help with these multiple-choice questions URGENTLY!! WILL mark brainliest. (one is attached below) the rest are here.

1) The elements in which Group would most likely form ions that have a charge of -3?

Select one:

a. Group 1

b. Group 3

c. Group 15

d. Group 16

2) The elements in which Group would most likely form ions that have a charge of +1?

Select one:

a. Group 1

b. Group 2

c. Group 17

d. Group 18

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

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

po-215 i got it right on the quiz

you didnt put any of the following

the right answer is c i just did the question.
