7 0

Answer:

The answer to your question is: letter D.

Explanation:

Double replacement reaction is when the cation of one reactant replaces the metal of the other reactant and vice versa.

a. 2SO2 + O2 —> 2S03                          This is a combination reaction

b. Zn + Cu(NO3)2 → Zn(NO3)2 + Cu      This is a single replacement reaction.

c. 2H2O2–> 2H2O + O2                         This is a decomposition reaction

d . AgNO3 + NaCl → AgCl + NaNO3      This is a double replacement reaction

How many liters of space are in 4.00x10^22 of O2 occupy at STP
irinina [24]

Answer:

V O2 = 1.623 L

Explanation:

  • 1 mol ≡ 6.022 E23 molecules

∴ molecules O2 = 4.00 E22 molecules

⇒ moles O2 = (4.00 E22 molecules O2)×(mol O2/6.022 E23 molecules)

⇒ moles O2 = 0.0664 moles

at STP:

∴ T = 25°C ≅ 298 K

∴ P = 1 atm

assuming ideal gas:

∴ V = RTn/P

⇒ V O2 = ((0.082 atm.L/K.mol)(298 K)(0.0664 mol))/( 1 atm)

⇒ V O2 = 1.623 L

What is the molar mass of calcium carbonate (CaCO3) ?
agasfer [191]

Answer: 15.1 grams

Given reaction:

Na2CO3 + Ca(OH)2 → 2NaOH + CaCO3

Mass of Na2CO3 = 20.0 g

Molar mass of Na2CO3 = 105.985 g/mol

# moles of Na2CO3 = 20/105.985 = 0.1887 moles

Based on the reaction stoichiometry: 1 mole of Na2CO3 produces 2 moles of NaOH

# moles of NaOH produced = 0.1887*2 = 0.3774 moles

Molar mass of NaOH = 22.989 + 15.999 + 1.008 = 39.996 g/mol

Mass of NaOH produced = 0.3774*39.996 = 15.09 grams
