Answer:
H₂: 0.48, N₂: 0.43; Ar: 0.09
Explanation:
First of all, sum all the pressures to know the total pressure in the mixture.
434 Torr + 389.9 Torr + 77.9 Torr = 901.8 Torr
Mole fraction = Pressure gas / Total Pressure
Mole Fraction H₂: 434 Torr /901.8 Torr = 0.48
Mole Fraction N₂: 389.9 /901.8 Torr =0.43
Mole Fraction Ar: 77.9 /901.8 Torr = 0.09
Remember: <u>SUM OF MOLE FRACTION = 1</u>
Answer:
B.
Explanation:
the SI unit for density is the kilogram per Cubic meter
Answer:
chemical change, or chemical reaction.
Explanation:
A change in matter that produces one or more new substances is a chemical change, or chemical reaction. In a chemical change, atoms rearrange to form new substances, which results in different physical properties, as well. ( you could have looked it up on google lol )
Answer:
Explanation: 1Pa 1 N/m^2. p = F/A and A = F/p = 300N /35 Pa = 8.57 m^2
This is a two step step reaction as shown below,
Step 1: Epoxidation of Alkene: In first step Cyclohexene is treated with peroxybenzoic acid in the presence of Dichloromethane which results in the formation of epoxide moiety.
Step 2: Nucleophillic Substitution Reaction: In second step the epoxide formed is treated with Sodium Methoxide which acts as a nucleophile and attacks the less hindered carbon of epoxide resulting in the formation of final product as shown below.
