Answer: The corresponding value of 
for this reaction at 84.5°C is 0.00232
Explanation:
Relation of with is given by the formula:
where,
= equilibrium constant in terms of partial pressure = ?
= equilibrium constant in terms of concentration = 0.0680
R = Gas constant = 
T = temperature =
= change in number of moles of gas particles = 
Putting values in above equation, we get:
Thus the corresponding value of for this reaction at 84.5°C is 0.00232
Answer: B
Explanation:
I think this is false. I really don't know the explination, but due to me just finishing this class. I'm going to go with B.
Answer:
Gold: 1.1 x 10²² atoms/cm³
Silver: 4.8 x 10²² atoms/cm³
Explanation:
100 g of the alloy will have 29 g of Au and 71 g of Ag.
19.32 g Au ____ 1 cm³
29 g Au ______ x
x = 1.5 cm³
10.49 g Ag ____ 1 cm³
71 g Ag _______ y
y = 6.8 cm³
The total volume of 100g of the alloy is x+y = 8.3 cm³.
Gold:
196.97 g Au____ 6.022 x 10²³ atoms Au
29 g Au _______ w
w = 8.9 x 10²² atoms Au
8.9 x 10²² atoms Au ____ 8.3 cm³
A ____ 1 cm³
A = 1.1 x 10²² atoms Au
Silver:
107.87 g Ag____ 6.022 x 10²³ atoms Ag
71 g Ag _______ w
w = 4.0 x 10²³ atoms Ag
4.0 x 10²³ atoms Ag ____ 8.3 cm³
B ____ 1 cm³
B = 4.8 x 10²² atoms Ag
Fire is a risk in all commercial kitchens. Open flames, grease, poor house-keeping practices, electrical hazards and flammable materials are common causes of restaurant fires.
What is an accidental fire?
Accidental fires are those in which the proven cause does not involve any deliberate human act to ignite or spread the fire.
Open flames, grease, poor house-keeping practices, electrical hazards and flammable materials are common causes of restaurant fires. Employers must implement effective administrative controls to protect employees and the business from the dangers of fire.
