The correct answer is false. The statement given does not describe a property in general. However, it speaks of a specific type of property which is the physical property. This property is the one that does not change the identity of a substance. A property can also be a chemical property where the identity of a substance is changed.
Answer:
Calculate the molar concentration of the NaOH solution that you prepared Number of moles of KHP = Number of moles NaOH = 2.476 x 10 -3 moles Number of moles NaOH = Mb x Vb Mb = 2.476 x 10 -3 moles / 0.0250 L (equivalence point) = 0.0990 M 3
Explanation:
Distance traveled by the race horse=6 furlongs
Converting the distance from furlongs to rods: 40 rods =1 furlong
![6 furlongs*\frac{40rods}{1furlong} =240rods](https://tex.z-dn.net/?f=6%20furlongs%2A%5Cfrac%7B40rods%7D%7B1furlong%7D%20%3D240rods)
Converting the distance from rods to yards, feet and miles: 5.5 yards = 1 rod, 3foot =1 yard, 1 mile = 5280 feet.
![240rods*\frac{5.5yards}{1rod}*\frac{3foot}{1yard}*\frac{1mi}{5280feet}=0.75mi](https://tex.z-dn.net/?f=240rods%2A%5Cfrac%7B5.5yards%7D%7B1rod%7D%2A%5Cfrac%7B3foot%7D%7B1yard%7D%2A%5Cfrac%7B1mi%7D%7B5280feet%7D%3D0.75mi)
The given speed of race horse = 40.7mi/hr
Calculating the time required:
![0.75mi*\frac{1hr}{40.7mi}*\frac{60min}{1hr}*\frac{60s}{1min}= 66.34s](https://tex.z-dn.net/?f=0.75mi%2A%5Cfrac%7B1hr%7D%7B40.7mi%7D%2A%5Cfrac%7B60min%7D%7B1hr%7D%2A%5Cfrac%7B60s%7D%7B1min%7D%3D%2066.34s)
Therefore, 66.34 s is required for a race horse to run six furlongs at 40.7 miles per hour.
Answer:
Co(cobalt) is the answer
Explanation:
Cobalt is a chemical element with the symbol Co and atomic number 27. Like nickel, cobalt is found in the Earth's crust only in chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal.
