1. 2Al(s)+6HCl(aq)⇒2AlCl₃(aq)+3H₂(g)

2. 2AgNO₃ (aq) + Cu (s)⇒Cu(NO₃)₂ (aq) + 2Ag (s)

3. 2C₃H₈O(l) + 9O₂(g) ⇒ 6CO₂(g) + 8H₂O(g)

<h3>Further explanation</h3>

There are several reactions that can occur in a chemical reaction: single replacement, double replacement, synthesis, decomposition or combustion, etc.

1.Al(s)+HCl(aq)⇒AlCl₃(aq)+H₂(g)

type : single replacement

balance :

2Al(s)+6HCl(aq)⇒2AlCl₃(aq)+3H₂(g)

2. AgNO₃ (aq) + Cu (s) ⇒ Cu(NO₃)₂ (aq) + Ag (s)

type : single replacement

balance :

2AgNO₃ (aq) + Cu (s)⇒Cu(NO₃)₂ (aq) + 2Ag (s)

3. C₃H₈O + O₂ ⇒ CO₂ + H₂O

type : combustion of alcohol

balance :

2C₃H₈O(l) + 9O₂(g) ⇒ 6CO₂(g) + 8H₂O(g)

What is the pressure of 62.76 g of carbon dioxide (CO2) gas if it occupies a volume of

Korolek [52]

Answer:

P = 995.6 atm

Explanation:

assuming ideal gas:

PV = RTn

∴ Tst = 25°C ≅ 298 K

∴ V = 35.00 mL = 0.035 L

∴ molar mass CO2 = 44.01 g/mol

∴ mass CO2(g) = 62.76 g

⇒ mol CO2(g) = (62.76 g)*(mol/44.01 g) = 1.426 mol

∴ R = 0.082 atm.L/K.mol

⇒ P = RTn/V

⇒ P = ((0.082 atm.L/K.mol)*(298 K)*(1.426 mol)) / (0.035 L)

⇒ P = 995.6 atm
