A= (99x1+0,8x2+0,2x3)÷100%=1,012
1,012≈1
The answer is 209.15cm3
The volume is directly related to the temperature of a gas. You can solve this question using Charles' law, but remember to convert the temperature from Celcius to Kelvin.
V1/T1= V2/T2
<span>200 cm3/ (33+273K)= V2/(47+273K)
V2= 200cm3 * 320/306= 209.15cm3</span>
Homogeneous because it is unable to be distinguished of the components Water and Salt
Answer:
D. Light waves travel fastest through a vaccumm
Explanation:
"In a vacuum , light waves move their fastest: 186,000 miles per second (300,000 kilometers per second). This is also the fastest that anything in the universe moves. But when light waves move through air, water or glass, they slow down."
Please mark me as brainliest! <3
Hopefully I could help! Good luck.
Answer:
