Answer:
B. The motorcyclist traveled southeast along a highway at 55 mph and reached the campsite in less than the two-hour estimated time.
Explanation:
<em>Velocity </em>is the rate at which an object changes position in a specific direction. It has both <em>magnitude and direction.</em>
Travelling <em>southeast</em> at <em>55 mph</em> is a <em>velocity</em>. It gives both speed and direction.
Statements A., B., and C. give the direction but not the speed.
The answer is Iron(II) Hydrogen Carbonate. It can also be known or referred as Ferrous Hydrogen Carbonate or even Iron(II) Bicarbonate. The known formula for this chemical is Fe(HCO3)2. The Molar Mass of this chemical is known as 177.8787. Here are some chemical reactions that may be equivalent to this chemical: FeCO3 + H2CO3 = Fe(HCO3)2; or Fe(HCO3)2 = FeCO3↓ + CO2 + H2O; or Fe(HCO3)2 + 2HNO3 = Fe(NO3)2 + 2H2O + 2CO2
