Answer:
use the formula pressure 1 ÷ temperature 1 = pressure 2 ÷ temp 2
so your equation would look like this,
p2= p1(T2)÷ T1
so p2 =5.5(18)÷23
so it would be 4.304347826
round as you must
Answer:
I'm not sure sorry
Explanation:
all I know is calcium=1 carbon=1 oxygen=3➡️calcuim=1 oxygen=1+carbon=1 oxygen=2

Answer:
4.86 × 10^-7m
Explanation:
Wavelength = C/f
C (Speed) of light = 3 × 10^8
f = 6.17 × 10^14
Wavelength = (3 × 10^8)/ (6.17 × 10^14)
= 4.86 × 10^-7m
