Answer:
1.67 atm.
Explanation:
- We can use the general law of ideal gas: PV = nRT.
where, P is the pressure of the gas in atm (P = ??? atm).
V is the volume of the gas in L (V = 5.0 L).
n is the no. of moles of the gas in mol (n = 0.5 mol).
R is the general gas constant (R = 0.0821 L.atm/mol.K),
T is the temperature of the gas in K (T = 203 K).
∴ P = nRT/V = (0.5 mol)(0.0821 L.atm/mol.K)(203 K)/(5.0 L) = 1.67 atm.
Here are your answers:
1. MgBr2 + Cl2 = MgCl2 + Br2
Balancing,
Already balanced.
Type of reaction: single displacement
2. Al + Fe2O3 = Al2O3 + Fe
Balancing,
2Al + Fe2O3 = Al2O3 + 2Fe
Type: single displacement reaction
3. AgNO3 + ZnCl2 = AgCl + N2O6Zn
Balancing,
2AgNO3 + ZnCl2 = 2AgCl + N2O6Zn
Type: double displacement reaction
MnO2
4. H2O2 ====== O2 + H20 [being catalyzed by manganese dioxide]
Balancing,
MnO2
2H2O2 ====== O2 + 2H2O
Type: decomposition reaction
5. Zn + HCl = ZnCl2 + H2
Balancing,
Zn + 2HCl = ZnCl2 + H2
Type: single displacement reaction
6. H2SO4 + NaOH = Na2SO4 + H2O
Balancing,
H2SO4 + 2NaOH = Na2SO4 + 2H2O
Type: Acid-base reaction
That took hella long!!! Hope it helps.
<span>4.9 L would be the answer to this question :)</span>
Their is 2 valence electrons
The answer that i found is 4.650
