select the correct number.\nthe equation shows neutralization of an acid and a base to produce a salt and water.\n2hcl + na₂o → xnacl + h₂o\nwhich value of x will balance the equation?
Answer
Explanation:
Step1: Count sodium atoms on left - hand side
On the left - hand side of the equation $2HCl+Na_2O\rightarrow xNaCl + H_2O$, in $Na_2O$, the number of sodium ($Na$) atoms is 2.
Step2: Balance sodium atoms
For the equation to be balanced, the number of sodium atoms on the right - hand side (in $xNaCl$) must equal the number on the left - hand side. Since each $NaCl$ has 1 sodium atom, if the number of sodium atoms is 2, then $x = 2$.
Answer:
2
