Answer: 10.3 mol/l
Explanation: Molality = concentration c = n/V
Amount of substance n = m/M = 150 g / 58.44 g/mol =
2,5667 mol . c = 2.5667 mol / 0.25 l = 10.2669 mol/l
c =
Answer:
- Initial: forward rate > reverse rate
- Equilibrium: forward rate = reverse rate
Explanation:
2NO₂(g) → N₂O₄(g) Kc=4.7
The definition of <em>equilibrium</em> is when the forward rate and the reverse rate are <em>equal</em>.
Because in the initial state there's only NO₂, there's no possibility for the reverse reaction (from N₂O₄ to NO₂). Thus the forward rate will be larger than the reverse rate.
Answer:
B. 1 triple bond and 2 single bonds
Explanation:
C2Cl2 has linear structure.
For its Lewis structure, the C2Cl2 molecule has a total of 22 valence electrons. Each Carbon (C) atom has 4 valence electrons and 7 atoms in each chlorine atoms.
So, after pairing in C2Cl2, Chlorine (Cl) form 2 single bonds, one with each carbon atom andboth the Carbon (C) atoms form one triple bond with each other.
Sugar flowers are there favorite. But any will lots of nearer do well.
D. keeping heat from moving out of the water
