Answer:Even if your door is closed, you would still smell the odors because of the space under the door and the space that is needed to close the door.
Explanation:
The rows are known as PERIODS and the columns are know as GROUPS.
Answer:
a.Low temperature
Explanation
Equation of reaction:
2NO2 <==> N2O4(g) ∆H = +ve
To cause the reaction to become darker brown means to produce more of NO2 gas. That is backward reaction.
Since the reaction is endothermic, decrease in temperature will shift the equilibrium position to the left thereby favouring backward reaction. This is in line with Me Chatelier's principle.
High pressure will rather favour forward reaction (it is not the right option).
Answer:
V = 1.2 × 10⁻⁶ m³
Explanation:
Volume is equal to length × width × height, since we are given these measurements in the question we can simply plug our numbers into the formula.
V = l × w × h
V = 1.64 x 10⁻² × 1.5 x 10⁻² × 4.8 x 10⁻³
V = 1.2 × 10⁻⁶ m³
