The question is incomplete. The complete question is :
A 100.0 mL flask is filled with 0.065 moles of A and allowed to react to form B according to the reaction below. The following experimental data are obtained for the amount of A as the reaction proceeds. What is the average rate of appearance of B in units of M/s between t = 10 min. and t = 30 min.? Assume that the volume of the flask is constant. A(g) → B(g)
Time 0.0 10.0 20.0 30.0 40.0
Moles of A 0.065 0.051 0.042 0.036 0.031
Solution :
Consider the following reaction as follows :

The experiment data is given as follows :
Time (min) : 0.0 10.0 20.0 30.0 40.0
Moles of A : 0.065 0.051 0.042 0.036 0.031
According to the rate of reaction concept, the rate can be expressed as a consumption of the reactant and formation of the product as follows :
Average rate : ![$= -\frac{d[A]}{dt} = \frac{d[B]}{dt} $](https://tex.z-dn.net/?f=%24%3D%20-%5Cfrac%7Bd%5BA%5D%7D%7Bdt%7D%20%3D%20%20%5Cfrac%7Bd%5BB%5D%7D%7Bdt%7D%20%24)
Now we have to calculate the average rate between 10.0 to 30.0 min w.r.t. A as follows :
Rate 


Therefore, the rate = 
Answer:
Firsthand association assigns energy throughout conduction. Radiation transpires when particles consume energy that progresses as a wave. The heat will run from the h2O to the ice continuously until the ice has absolutely melted so both elements have reached the same temperature.
Explanation:
Solid, ductile (can conduct heat), malleable (can be shaped differently).
Answer:
A chemical change occurred, so even if Cash heats it, the white solid will remain.
Explanation:
- A physical change occurred, so if Cash heats it, the white solid will dissolve to form the original mixture of clear liquids.
- A physical change occurred, so even if Cash heats it, the white solid will remain.
- A chemical change occurred, so if Cash heats it, the white solid will dissolve to form the original mixture of clear liquids.
- A chemical change occurred, so even if Cash heats it, the white solid will remain.
<em>The correct answer would be that a chemical change occurred, so even if Cash heats it, the white solid will remain.</em>
Chemical changes occur when atoms in a substance or mixture of substances are rearranged, leading to the formation of new substances.
<u>In this case, the mixture of the two clear liquids led to the formation of gas in form of bubbles and a white solid forms that settle at the bottom. The formation of these 2 substances from the mixture of the two clear liquid is an indication of chemical reaction/changes. Hence, even if cash heats the resulting mixture, the white solids will likely remain.</u>
