The molar mass of carbon dioxide (CO2) is 44.01 g/mol. The molar mass of water (H2O) is 18.01 g/mol. A reaction uses 528 g of CO
Black_prince [1.1K]
CO₂  +  H₂O  ------->  H₂CO₃

moles of CO₂ = \frac{MASS  of  Carbon}{ MOLAR  MASS}
              
                       = \frac{528  g}{44.01  g / mol}
 
                       =  11.997 mol

mole ratio of  CO₂  :  H₂O  =   1  :  1
           
            ∴ moles of H₂O  =  (`11.997 mol )  *  1
                                       =  11.997 mol
                                       ≈  12  mol

An ____,or an element located in group 7A, will form a salt when reacted with a metal atom.
stiv31 [10]

Answer:

B. Halogen

Explanation:

Halogens are the family of chemical elements found in the group VIIA of the periodic table which means they possess seven (7) outer electrons. Some examples of halogens are Fluorine (F), Iodine (I), Bromine (Br), and Chlorine (Cl).

A halogen, or an element located in group 7A, will form a salt when reacted with a metal atom.

For example, when Chlorine reacts with Sodium it would form a salt known as Sodium Chloride.

Na + Cl ----> NaCl
