Answer:
Volume of gold is 9.64 L
.
Explanation:
Given data:
Mass of gold = 85 g
Temperature = standard = 273 K
Pressure = standard = 1 atm
Volume of gold = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
Now we will calculate the number of moles of gold.
Number of moles = mass/molar mass
Number of moles = 85 g/ 197 g/mol
Number of moles = 0.43
1 atm × V = 0.43 mol ×0.0821 atm.L/ mol.K × 273 K
V = 9.64 atm.L / 1 atm
V = 9.64 L
The question is incomplete, here is the complete question:
The given chemical equation follows:
What is the equilibrium constant expression for the given system?
<u>Answer:</u> The expression of equilibrium constant for the given equation is
<u>Explanation:</u>
Equilibrium constant is the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as
For a general chemical reaction:
The expression for is written as:
The given chemical equation follows:
The expression for for above equation follows:
Hence, the expression of equilibrium constant for the given equation is
Answer:
H2SO4 + 2(NaOH) -----> Na2SO4 + 2(H2O).

Answer:
Multicellular
Explanation:
Prokaryotic cells are unicellular because the do not have a nucleus and lack organelles, while eukaryotic cells do have a nucleus, have organelles, and are are multicellular. :)
