Answer:
Explanation:
- The atomic mass of nitrogen is 14.0067 g/mol.
- The atomic mass of oxygen is 15.9994 g/mol.
This means the molecular mass of nitrogen dioxide is g/mol.
Dividing this molecular mass of the compound we need to find, we get that
.
So, the final answer is
Use the equation m1 * v1 = m2 * v2
Example: (2.75 L)(1.5 M) = (12.0 M)(v2) then solve for v2
You may have to solve for m2 as well just plug and chug
Bleach contains sodium chlorine and oxygen
R = 0.082 atm
T = 35.0 + 273 = 308 K
P x V = n x R x T
P x 4.00 = 2.75 x 0.082 x 308
P x 4.00 = 69.454
P = 69.454 / 4.00
P = 17.4 atm
Answer A
F.Wave C has a higher frequency than wave D
D. Wave B would sound quieter than wave C
B. Wave D has a higher amplitude than wave A
Explanation:
- A high amplitude wave is a high-energy wave, and a low-amplitude wave is a low-energy wave.
- In sound waves, a high amplitude sound will be loud, and a low amplitude sound will be quiet.
- Frequency is the number of ways that pass by each second, measured in hertz.
- The amplitude and frequency are the two factors that affect the energy which is transferred by a wave.
- The height of the wave, and the number of waves passed by each second in case of amplitude and frequency.
