Performing the 5% Sodium Hydroxide Solubility Test. If your compound is water-soluble, proceed to Part 3.

All our lives, even if we donât know it, weâve been dreaming of the New Earthâthe Heaven that will last forever. Whenever we see beauty in water, wind, flower, animal, man, woman, or child, we see just a sample of what Heaven will be like.We should expect this New Earth to be like the Garden of Eden, only better.lthough the painting is still the same, it looks once again like it was meant to look. The New Earth will still be Earth just as we, in our new bodies, will still be ourselves. So we can expect New Earthâs sky to be blue and its grass green.
Earth was once a âwaterworldâ much like the one depicted by Hollywood, scientists believe. A new model of the early Earth suggests that until around 2.5 billion years ago oceans covered almost the whole of the planet. Just 2% to 3% of the Earthâs surface would have been dry land, compared with 28% today. Earth was once a âwaterworldâ, scientists believe. The Earth at that time may have resembled the way it looked in Waterworld, the 1995 post-apocalyptic sci-fi movie starring Kevin Costner. In the film, humanity struggles to survive after the ice caps melt and inundate the planet with water.
