The Volumes can be calculated from Masses by using following Formula,
Density = Mass / Volume
Solving for Volume,
Volume = Mass / Density
Mass of Both Gases = 14.1 g
Density of Argon at S.T.P = 1.784 g/L
Density of Helium at S.T.P = 0.179 g/L
For Argon:
Volume = 14.1 g / 1.784 g/L
Volume = 7.90 L
For Helium:
Volume = 14.1 g / 0.179 g/L
Volume = 78.77 L
Answer:
D. fields moves in longitudinal waves
Explanation:
Answer:
they both have seven electrons in the outer shell
they are all just one electron shy of having full shells
Answer:
A(yellow) = 52
Explanation:
A(yellow) = A(total) - A(red)
= 11×6 - 7×2
= 66 - 14
= 52
A) 4
pH=-log[H+]
pH=-log(10^-4)
B) Weaker
pH of orange juice=4
pH of coffee=5
An acid with pH of 4 is stronger than a pH of 5
C) 7, neither/neutral
pH of water=7
