Le Chatelier's Principle says that when something disrupts the equilibrium, the system adjusts to minimize the effect of that disturbance. If 0.1 M HCl solution is added, this dissociates into H+ and Cl- ions, so there will be more Cl- ions in the system. This causes the reaction to go in the reverse direction (equilibrium shifts to the left) to reduce the amount of Cl-.
Since this also consumes Ag+ ions, the concentration of Ag+ (aq) will decrease.
The answer is the second choice.
Mols is shorthand for molarity, a unit of measurement corresponding to moles/liter. A mole is just a number for example “ a dozen”. Mole is also spelled mol in chemistry so they do mean the same.
Thank me by clicking the heart ❤️. Thanks!
=58.464 kg/hr
width= 21.0 feet
length= 20.0 feet
snowflake mass=1.60 milligrams
1 foot^2=1450 snowflakes per minute
area of lawn=length*width
area=(21.0)(20.0)
area=420 feet^2
1450 snowflakes at 1.60 milligrams per snowflake:
(1.60)(1450)=2320 milligrams
2320 milligrams to kilograms:
=(2320 mg)(1 gram/1000 mg)(1 kilogram/1000 grams)
=(2320)(1/1000)(1/1000)
=(2.32)(1/1000)
=0.00232 kg per minute
0.00232 kg per minute to kg per hour:
=(0.00232 kg/1 minute)(60 minutes/1 hour)
=(0.00232)(60)
=0.1392 kg per hour per square foot
For the total lawn's accumulation in kilograms per hour, multiply by area:
=(0.1392 (kg/hr) per 1 foot^2)(420 feet^2)
=58.464 kilograms of snow accumulate on the lawn per hour
Answer:
288.19
Explanation:
C19 = 12.01 = 228.19
H28 = 1.00 x 28 = 28
O2 = 16 x 2 = 32
228.19 + 28 + 32 = 288.19
