Which of the following equations shows a chemical change?
NH3(g)→NH3(l) N H 3, which is a gas right-arrow N H 3, which is a liquid C2H5OH(l)→C2H5OH(g) C 2 H 5 O H, which is a liquid right-arrow C 2 H 5 O H, which is a gas H2O(s)→H2O(g) H 2 O, which is a solid right-arrow H 2 O, which is a gas C3H8+5O2→3CO2+4H2O
The equation that shows a chemical change is C3H8+5O2→3CO2+4H2O.
The equation that shows a chemical change is:
C3H8 + 5O2 → 3CO2 + 4H2O
In this equation, the reactants (C3H8 and O2) are combining to form different products (CO2 and H2O). This indicates a chemical change, as the molecular structure and composition of the substances are being altered.
The equation that shows a chemical change is C3H8 + 5O2 → 3CO2 + 4H2O.
A chemical change, also known as a chemical reaction, occurs when the substances involved undergo a transformation, resulting in the formation of new substances with different properties. In this equation, the reactants (C3H8 and O2) combine to form the products (CO2 and H2O). Since the substances on both sides of the equation are different, it indicates a chemical change.
To determine if an equation shows a chemical change, you can identify the reactants and products and compare them. If they are different substances, it suggests the occurrence of a chemical reaction. In this case, the reactants (C3H8 and O2) combine to form the products (CO2 and H2O), indicating a chemical change.
