Photon is the smallest possible unit of electromagnetic energy that can be absorbed or emitted.
I think it's N and O because on the left 3 times 2 gives you O6 on the left but O3 on the right. Then on the right 1×2= N2 but on the right it's just N1
Answer:
Variability of data around the mean is best expressed through the standard deviation.
Explanation:
We have some statistical metrics, and we need to find the best measure of the variability of data around the mean.
First variable is mode. Mode of a set of data values is the value that appears most often. It means the most frequent data.
Second variable is Median. The median is a simple measure of central tendency. It is located around 50% of data range.
Third variable is standard deviation. The standard deviation is found by taking the square root of the average of the squared deviations of the values subtracted from their average value. It means, it will show the dispersion of data around the average value.
According to the definition presents for the three variables, Standard deviation is the most appropriate measure of variability of data around the mean.
Answer:
Mol. mass of ethyl alcohol =C2H5OH=46
No. of moles of ethyl alcohol =4660=1.304
Mol. mass of methyl alcohol =CH3OH=32
No. of moles of methyl alcohol =3240=1.25
′XA′, mole fraction of ethyl alcohol =1.304+1.251.304=0.5107
′XB′, mole fraction of methyl alcohol =1.304+1.251.25=0.4893
Partial pressure ethyl alcohol =XAp˙A0=0.5107×44.5=22.73mmHg
Partial pressure methyl alcohol =XBp˙B0=0.4893×88.7=73.40mmHg
Total vapour pressure of solution =22.73+43.40=66.13mmHg
Mole fraction of methyl alcohol in the vapour
=Total vapour pressurePartial pressure of CH3OH
Explanation:
I HOPE THIS HELPS YOU
Answer:
So if you are buying, Inorganic is cheaper but at the cost of it's quality, organic fertilizer is better quality that's why it is more expensive, both work so if you want the cheaper option that's fine it still works
