In this double replacement reaction, which are the products? hcl + naoh —> ______?
Anarel [89]
The answer is:  " NaCl + H₂O " ; (or; write as:  " H₂O + NaCl " ) .
________________________________________________________
Specifically:
_________________________________________________________

    HCl + NaOH  —>  NaCl + H₂O  ;   or; write as:

    NaOH + HCl   —>  H₂O + NaCl  .
_______________________________________________________
            This type of "double-replacement" reaction is called "neutralization".
 
             Since we are adding a strong acid to a strong base (reactants), we know that the product will be:  1) a salt ; and 2) water.  Since we know one of the reactants will be "water" (H₂O) ; we can find the base (i.e. , the "remaining product") from selecting the "unused elements" to form the corresponding "salt".

14. As the moles of salt added are increased, what<br> happens to the melting point of the water?
Vika [28.1K]
Salt lowers the freezing/melting point of water, so in both cases the idea is to take advantage of the lower melting point. Ice forms when the temperature of water reaches 32 degrees Fahrenheit (0 degrees Celsius).
