True or False: 1. A mixture is a material made up of two or more different substances which are physically combined and the identities of each substance are retained. 2. A heterogeneous mixture has different proportions or unequal amounts of components evenly distributed throughout the mixture. 3. A homogeneous mixture has equal or the same amount of components. 4. The salt disappears when mixed with water because the salt particles spread evenly in the water.
