The dimensions of room are . Thus, volume of room will be:
Converting to
Since,
Thus,
Now, concentration of carbon monoxide in the urban apartment is , thus, mass of carbon monoxide can be calculated as follows:
Rearranging,
Putting the values,
converting
Since, thus,
Therefore, mass of carbon monoxide present in the room is .
Answer:
This experiment is uncontrolled because two different masses of substance A are used.
Explanation:
A controlled experiment is a structured experiment aimed at testing a particular observation or observations. The setup of a controlled experiment helps to determine the reason why a particular observation occurs and what must have led to it.
In the experiment highlighted above, different masses of a substance were used, they were heated to different temperatures. The set up does not show any correlation between the masses of substances heated and the temperatures. It is even difficult to try to predict the hypothesis for this kind of experimental set up. All the variables in play can best be assumed to be independent of one another.
The probability that the resulting offspring will be tall in ratio is 1:2:1
Chemical properties of neon are colorless, tasteless and odorless.
