Answer:
In general, the magnetic field is strongest close to the wire and weaker farther away. In fact, the magnetic field weakens as 1/r1/r where rr is the distance from the wire. This can change a bit depending on the length and shape of the wire. Far enough away, the magnetic field decays as 1/r21/r2 .
Answer:
Mole fraction of solute (heptane) → 0.73
Explanation:
Mole fraction = Moles of solute or solvent / Total moles
Let's calculate the moles of everything:
Moles of solute → Mass of solute / Molar mass
36 g / 100 g/mol = 0.36 moles
Moles of solvent → Mass of solvent / Molar mass
16 g / 119.35 g/mol = 0.134 moles
Total moles = 0.36 + 0.134 = 0.494 moles
Mole fraction of solute = 0.36 / 0.494 → 0.73
Answer:
organic chemistry is chemistry focused on structure and composition, extending to recations and properties of compounds.
often centered around compounds with carbon.
alcohols, amines, and aldehydes are some groups that are studied on organic chemistry
SHORT ANSWER:
a) chemistry focused on the structure qnd composition of compounds
b) alcohols, amines, aldehydes
Refrigerants are chemical mixtures composed of several substances. During the HVAC cycle, <span>refrigerants can usually exist in several states.
These substances have very dangerous and destructive effects on the environment.
Based on this, if two or mire </span><span>refrigerants are mixed together, the mixture must be recovered into a separate tank and sent to the specialized facility to destroy it.
The destruction of the mixture should only be done by experts in specialized facilities.
Hope this helps :)</span>
