Clouds are a source of Infrared Radiation. When cloud coverage increases, the infrared radiation also increases. So the clouds basically act as space heaters. This emits energy towards the ground, which is what makes cloudy nights warmer. While with clear sky’s all the heat from the day just escapes back into the atmosphere so the temperatures will be colder.
Is not a single replacement
<h3>Further explanation</h3>
A single replacement reaction is a chemical reaction in which one element replaces the other elements of a compound to produce new elements and compounds
Reactions
A+BC--> AC+B
Metal halogens can force metal halide ions in the order F> Cl> Br> I
Oxidation : F₂> Cl₂> Br₂> I₂
Reaction
NaBr+I₂ -> NaI+Br₂
Then the reaction will not occur because I₂ cannot oxidize Br, or the reaction is said to be non-spontaneous
Answer:
0th order with respect to oxygen.
Explanation:
Whenever we have a table with the molarity of a substance against time, the best idea is to input the time into one cell of Excel and molarity into the other adjacent cell of Excel.
We wish to produce 3 plots: plot 1 would contain time on the x-axis and molarity values on the y-axis. In case we get a straight line in the graph, we can verify that this is a 0th order reaction.
Plot 2 would need us to calculate the natural logarithm of each concentration and plot time on the x-axis and ln of each molarity on the y-axis. In case we get a straight line, we can verify a 1st order reaction.
Plot 3 would require calculating the reciprocal of each molarity, that is, 1/[O2] in each case. Plotting time on the x-axis and 1/[O2] on the y-axis would yield a graph. In case this graph is linear, then the reaction order is 2nd.
We plot each graph and add trendline in Excel. None of the graphs is perfectly linear, so the only data we can rely on is the R-squared coefficient. The closer it is to 0, the closer your points resemble a line. Out of all three graphs, the highest R-squared value is seen for the 0th order rate law at a value of 0.8721 against 0.7749 for the 1st and 0.6255 for the second.

Answer:
The change during the burning of a match stick is a irreversible chemical change while the change when a liquid starts boiling is reversible chemical change.
