The correct answer to the question that is being presented above would be letter c. change in particle size. Changes in pressure, temperature, and concentration are stressors that cause change in chemical equilibrium.
Combustion of <span>acetylene :
</span><span>molar ma</span>ss acetylene ( C₂H₂ ) = 26.0 g/mol and CO₂ = 44.0 g/mol
<span>
2 C₂H₂ + 5 O₂ ---> 4 CO₂ + 2 H₂O
</span>
2 moles C₂H₂ --------> 4 moles CO₂
? moles C₂H₂ --------> 1.10 moles CO₂
moles C₂H₂ = 1.10 * 2 / 4
moles C₂H₂ = 0.55 moles of C₂H₂
Mass acetylene:
m = n * mm
m = 0.55 * 26.0
m = 14.3 g
hope this helps!
Volatile organic compounds are compounds
that easily evaporate at standard room temperature and pressure. They are
considered harmful to the environment if regulations are not followed. Examples
of this are:
Benzene
Ethanol
Benzopyrene
Ethenone
Acetic acid
Methane
Butane
Heptane
Pentane
A tea kettle holds on average about 1.7-2 Liters of water. So the answer should be 2 Liters
<span>number of moles= mass / molecular mass
mass=131.50g
molecular mass of Zn(NO3)2 =189.39 g/mol
number of moles = 131.50 g/189.39 g/mol =0.69433 mol</span>
