Answer:
C. The balloon with CH4 has the same moles of gas molecules as the balloon with H2
Explanation:
Based on combined gas law, gases under the same pressure, temperature and volume have the same number of moles. With this information we can say the rigth statement is:
<h3>C. The balloon with CH4 has the same moles of gas molecules as the balloon with H2</h3>
Answer: It changed in identity and properties.
Explanation:
Answer:1.4
Explanation:
Angle of incidence= 38°
Angle of refraction=26.3°
From Snell's law: n= sin i/sinr
sin i= 0.6157
sin r= 0.4430
n= 0.6157/0.4430=1.4
Note, n is dimensionless
