Answer:
Explanation:
From the combustion of carbon, the reactions occurring in limited oxygen conditions are:
If it occurs in excess, then any leftover CO changes to CO2. i.e.
---- (1)
----- (2)
From (1), the enthalpy change is:
From (2), the enthalpy change is:
Subtracting (2) from (1), we get:
<u> </u>
The enthalpy change ΔH of the reaction = -110.5 kJ/mol
Not quite sure what you mean by matter ? Yes air is matter and yes it does matter ! Air is various gasses that support life and other things ! We use air for so many things, it's very important c:
Answer:
B. Measures of central tendency
Explanation:
Mean, median and mode are best described as measures of central tendency of a given data set.
Mean is the average of the samples given
Mode is the data point with the most frequent occurrence
Median is the data point that lies in the middle
- All these parameters tells us how far a data point is from the middle or how close they are.
