Which of the following demonstrates that reactants and profucts are chemically different?
A. Zn+2HCI-->2HCI+Zn
B. Zn+2HCI-->H2+ZnCI2
C. H2O+C4H10-->H2O+C4H1
D. C4H10+H2O-->C4H10+H2O
Is the answer C?
I don't agree with your answer. What is different about the reactants and products in C? I don't see any difference (except for a typo on C4H1 and I'm sure you meant to type in C4H10.)
Yea I did mean to put C4H10 so sorry. Is the answer b?
Yes, the answer is b.
No, the answer is actually B.
To determine whether the reactants and products are chemically different in a chemical equation, you need to analyze the chemical formulas of each compound involved.
In option A, the reactants are Zn and HCl, and the products are HCl and Zn. Although the order has changed, the chemical formulas remain the same, so they are not chemically different.
In option C, both sides of the equation have the same reactant (H2O) and product (C4H10), so they are not chemically different.
In option D, both sides of the equation have the same reactants (C4H10 and H2O) and product (C4H10), so they are not chemically different either.
Option B, on the other hand, shows that the reactants (Zn and 2HCl) combine to form different products (H2 and ZnCl2). The formation of new compounds with different chemical formulas indicates that the reactants and products are chemically different. Therefore, the correct answer is B.
