The answer is a compound because it is only a compound that can be broken to elements. for eg. H2o is a compound and be broken to element of 2 molecules of hydrogen and oxygen
Answer:
V₁ = 0.025 Liters = 25 ml
Explanation:
P₁ = 6 Atm P₂ = 7800mm/760mm/Atm = 0.01 Atm
V₁ = ? V₂ = 29 Liters
T₁ = 115 K T₂ = 225 K
P₁V₁/T₁ = P₂V₂/T₂ => V₁ = P₂V₂T₁/P₁T₂
V₁ = (0.01 Atm)(29L)(115K)/(6 Atm)(225K) = 0.025 Liters = 25ml
The density of the carbon tetrachloride is 1.59 g/mL.
Mass of CCl₄ = 703.55 g – 345.8 g = 357.75 g
Density = mass/volume = 357.75 g/225 mL = 1.59 g/mL
2C2H2(l) +5O2(g)→ 4Co2(g) + 2H2O
The limiting reactant for reaction above is O2
<u><em>explanation</em></u>
The limiting reagent is determined using mole ratio of both reactant.
that is the mole ratio of C2H2:O2 which is 2:5 .
The mole ratio above implies that 37.0 mole of C2H2 needs 37.0 moles x5/2=92 moles of O2.
<em>Since the available moles of O2 was 81.0 mole and 92 moles are required to completely react with C2H2</em><em> ,</em> <u>O2 is the limiting reagent.</u>
