Which of the following shows a physical change?
A. H2(g)+O2(g)=H2O(l)
B. 2CH3OH(l)+3O2(g)=2CO2(g)+4H2O(l)
C. NaCl(s)=NaCl(aq)
D. 2AgNO3(aq)+CaBr2(aq)=2AgBr(s)+Ca(NO3)2(aq(

Respuesta :

The option that shows a physical rather than only a chemical change is H2(g)+O2(g)=H2O(l).

What is a physical change?

A physical change implies a change in physical characteristics such as:

  • Color
  • State of the matter
  • Density

Which one is an example of a physical change?

The reaction  H2(g)+O2(g)=H2O(l) is an example of a physical change. This is because hydrogen and oxygen are usually in a gas state but once they bond and form water they change to a liquid state.
