1) The forward reaction is N2 (g) + O2 (g) → 2NO
(that reaction requires special contitions because at normal pressures and temperatures N2 and O2 do not react to form another compound.
2) The equiblibrium equation is
N2 (g) + O2 (g) ⇄ 2NO
3) Then, the reverse reaction is
2NO → N2(g) + O2(g)
Answer: 2NO → N2(g) + O2(g)
Acetone (systematically named propanone)
Answer: The new pressure of the gas in Pa is 388462
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas at STP =
= final pressure of gas = ?
= initial volume of gas = 700.0 ml
= final volume of gas = 200.0 ml
= initial temperature of gas = 273 K
= final temperature of gas =
Now put all the given values in the above equation, we get:
The new pressure of the gas in Pa is 388462
Molar mass of cuso4=63.5+32+4*16= 159.5 g
6.02*10^23 molecules weigh=159.5 g
1 molecule weigh=159.5/6.02*10^23 g
3.36 × 10^23 molecules weigh=159.5/6.02*10^23*3.36× 10^23
=89.023g
Answer:
Explanation:
substance (as an acid or salt) that when dissolved (as in water) conducts an electric current.
