sodium metal
+
chlorine gas
→
table salt
How does the mass of the sodium metal and chlorine gas involved in the reaction, compare to the mass of the table salt produced?
O The mass of the sodium metal and chlorine gas combined is equal to the mass of the table salt that is produced.
O The mass of the sodium metal and chlorine gas combined is larger than the mass of the table salt produced.
O The mass of the sodium metal and chlorine gas combined is less than the mass of the table salt produced.
O The mass of the sodium metal is equal to the mass of chlorine gas used and the table salt produced.
