Coppers molecular weight is 63.546 u
Answer:
The definition of an absolute reference frame would be that fixed reference frame that every observer would rest at all times in his/her state of motion.
Explanation:
The H+ in a solution that has a Ph of 8.73 is calculate as follows
Ph is always = - log (H+)
H+ = 10^-Ph
H+ is therefore = 10 ^- 8.73
H+ = 1.86 x10^-9 M
Magnetic separation is a method that uses magnetic force to remove the magnetically sensitive material from a mixture. Because iron is attracted by magnets, this is the ideal method for separating sand and iron fillings.
Magnetism was the physical attribute that allowed this combination to be separated. I used the magnet to separate the iron filing from the sand in the mixture. The magnet attracted the iron filings but not the sand. We were able to separate the iron filings from the sand as a result of this.
Because iron is magnetic while the other two are not, a magnet may be used to pull the iron filings out of the mixture while leaving the salt and sand. Sand is not water-soluble, although salt is. This implies they may be combined in water and swirled together. The salt dissolves, but the sand does not.
