Answer:
The International Bottled Water Association (IBWA), Alexandria, Va., and Beverage Marketing Corporation (BMC), New York, recently released 2015 bottled water statistics showing that Americans' consumption of bottled water increased by 7.9 percent and bottled water sales were up 8.9 percent from the previous year.

Answer:
A chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus and minus signs.
Explanation:
Answer: Option (b) is the correct answer.
Explanation:
The elements which have excess or deficiency of electrons will react readily.
Atomic number of Mn is 25 and electronic configuration of 
is [Ar]
. This configuration is stable.
Atomic number of Cr is 24 and electronic configuration of 
is [Ar]
. This configuration is not stable.
Atomic number of Fe is 26 and electronic configuration of 
is [Ar]
. This configuration is stable.
Atomic number of Cu is 29 and electronic configuration of 
is [Ar]
. This configuration is not stable.
Atomic number of Al is 13 and electronic configuration of Al is 
. This configuration is not stable.
Atomic number of Ba is 56 and electronic configuration of 
is [Kr]
. This configuration is stable.
Atomic number of Mg is 12 and electronic configuration of 
is 
. This configuration is stable.
Atomic number of Sn is 50 and electronic configuration of Sn is [Kr]
. This configuration is stable.
Thus, we can conclude that out of the given options, only Fe and reactants would lead to a spontaneous reaction as they have incomplete sub-shells. Therefore, in order to gain stability they will readily react.
