Answer:
a > c > b
Explanation:
As higher is the strength and stiffness of the bond between two atoms, more stable it is, and more difficult is to these bonds vibrate. So, the stretching vibration decreases when the strength and stiffness increases.
As more bonds are done between the atoms, more strength, and stiffness they have. So, the order of increase is:
simple bond > double bond > triple bond
And the increased frequency of vibration is:
triple bond > double bond > simple bond
An alkane is a hydrocarbon that has only simple bonds between carbons, an alkene is a hydrocarbon with one double bond between carbon, and an alkyne is a hydrocarbon with one triple bond. So, the increase in vibration of them is:
alkyne (a) > alkene (c) > alkane (b)
Answer:
One billion
Explanation:
A nanometer is a BILLIONTH of a meter which means it takes one billion to equal a meter
In order to knw hw stable an atom is
Answer:
2.5 militers (mL) of digoxin solution
Explanation:
if 1 microgram = 0.001 miligram
then 62.5 micrograms = X miligrams
X = (62.5 × 0.001) / 1 = 0.0625 miligrams
the we calculate the number of militers of digoxin needed by the patient:
if we have 0.0250 miligrams of digoxin in 1 mililiter of solution
then we have 0.0625 miligrams of digoxin in X mililiters of solution
X = (0.0625 × 1) / 0.0250 = 2.5 militers (mL) of digoxin solution
