What is the correct balanced equation for making water from hydrogen and oxygen?

The actual reaction to make water is a bit more complicated: 2H2 + O2 = 2H2O + Energy. In English, the equation says: To produce two molecules of water (H2O), two molecules of diatomic hydrogen (H2) must be combined with one molecule of diatomic oxygen (O2). Energy will be released in the process.

Is sound made of matter?

The “particles” of light are called photons and have no mass. In contrast, matter is made up of particles that do have mass. Sound is a little different in that it is the propagation of a pressure wave through a medium of particles. Since it is a wave, it is not considered a form of matter.
