Answer : The rate of consumption of 
is, 
Explanation : Given,
Moles of = 
Volume of solution = 170 mL = 0.170 L (1 L = 1000 mL)
Time = 170 s
First we have to calculate the concentration.
Now we have to calculate the rate of consumption.
Thus, the rate of consumption of is,
The answer:
<span>When the volume of a gas is changed from 3.6 L to 15.5 L, the temperature will change from ?? oC to 87°C
application of charles law
charle's law tells that
T1/ V1 = T2 / V2, T must be in kelvin
it is given that V1 = 3.6 L, V2 = 15.5 L,
T2= </span><span>87°C= 360.15 K
</span>
so to find T1, T1 =(T2 / V2) x V1
T1= (360.15 / 15.5) * 3.6= 83.64° K = - 190.15° C
Answer:
the answer is B 200%
Explanation:
cause its the second column
Answer:
Propane
Explanation:
From the question given, we were told that 0.1240 kg of propane reacted with excess oxygen to produce 0.3110kg of carbon dioxide.
Since the reaction took place in the presence of excess oxygen, therefore, propane is the limiting reactant as all of it is used up in the presence of excess oxygen.
