Answer:
Mass = 25.08 g
Explanation:
Given data:
Volume of fluorine = 29.6 L
Temperature = standard = 273.15 K
Pressure = standard = 1 atm
Mass of fluorine = ?
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
n = PV/RT
n = 1 atm × 29.6 L / 0.0821 atm.L/ mol.K × 273.15 K
n = 1.32 mol
Mass of fluorine:
Mass = number of moles × molar mass
Mass = 1.32 mol ×19 g/mol
Mass = 25.08 g
When fireworks go off, they produce smoke, which is evidence of a new substance being created.
An acid base reaction occurs since we know that vinagar is just acetic acid and baking soda is just sodium bicarbonate. The vinagar (weak acid) is going to react with the bicarbonate (weak base) to create carbonic acid which decomposes into carbon dioxide and water. I hope this helps. Let me know in the comments if anything is unclear.
<u>Answer:</u> The equilibrium constant expression for the given equation is written below.
<u>Explanation:</u>
Equilibrium constant in terms of partial pressure is defined as the ratio of partial pressures of products to the partial pressures of reactants each raised to the power their stoichiometric ratios. It is expressed as 
For the general chemical equation:
The expression of 
follows:
For the given chemical equation:
The expression of for above equation follows:
Hence, the equilibrium constant expression for the given equation is written above.
