Answer:
The concentration of chloride ion is 
Explanation:
We know that 1 ppm is equal to 1 mg/L.
So, the 
content 100 ppm suggests the presence of 100 mg of in 1 L of solution.
The molar mass of is equal to the molar mass of Cl atom as the mass of the excess electron in is negligible as compared to the mass of Cl atom.
So, the molar mass of is 35.453 g/mol.
Number of moles = (Mass)/(Molar mass)
Hence, the number of moles (N) of present in 100 mg (0.100 g) of is calculated as shown below:
So, there is 
of present in 1 L of solution.
In this case, you are given the water density (62.4lb/ft3) and the water volume (10,000 gallons). But the unit used in the density and gallon is different, so you need to convert it. The calculation would be:
mass= density * volume
mass= 62.4 lb/ft3 * 10,000 gallons * (231 inch3/gallon) * (1 ft3/ 1728 inch3)
mass= 83,416.66 lbs= 81417 lbs
Answer: B) Electromagnetic waves can travel through empty space.
Explanation:
Conduction: This type of heat transfer happens when there is direct contact between the two object. Example: heating a pan on stove.
Convection: This type of heat transfer happens when there is a movement of fluid (liquid or gas) due to the movement of hot layers to the top and cold layers to the bottom which leads to convection currents. Example: Heating of swimming pool.
Radiation: This type of heat transfer happens when there is direct transfer of energy through empty space.The electromagnetic radiation from the surface of an object which is due to the object's temperature is radiation. Example: Heating of earth's surface.
Answer:
The Flow of science keeps going because not everything is fully discovered yet. New things are discovered everyday and are also made better as well.
