Answer:
a) 3.0076 E24 atoms
Explanation:
∴ mass Cl2 = 354.22 g
∴ molar mass Cl2 = 70.906 g/mol
⇒ mol Cl2 = (354.22 g)*(mol/70.906 g) = 4.9956 mol
⇒ atoms Cl2 = (4.9956 mol)*(6.022 E23 atoms/mol)
⇒ atoms Cl2 = 3.008 E24 atoms
Answer:
The cathode of a spontaneous electrochemical cell is the cell in which metal cations undergo reduction. The electrons are supplied by the anode. Without much thought, we can conclude magnesium is much less favorably reduced than gold.
Answer:
819 K
Explanation:
Given data
- Initial pressure (P₁): 1 atm (standard pressure)
- Initial volume (V₁): 250 mL
- Initial temperature (T₁): 273.15 K (standard temperature)
- Final pressure (P₂): 0.500 atm
- Final volume (V₂): 1500 mL
- Final temperature (T₂): ?
We can find the final temperature using the combined gas law.
"X" in the reaction above is acetic acid with a chemical formula CH3COOH. The chemical reaction would be NaOH + CH3COOH = NaCH3COO + H2O. This is a neutralization reaction in which it produces a salt and water. The salt produced is called sodium acetate.
8 carbons is "oct" prefix (like polygons)
No pi bonds is "ane" suffix.
put it together to get.... Octane
