The scientist who discovered the first real evidence of the big bang was EDWIN HUBBLE.
Astronomer Edwin Hubble was an American astrophysicist. He contributed in so many ways to humanity during his lifetime. One of his contribution is that, his observation showed the existence of galaxies that are far beyond the milky way; these galaxies were moving away from one another. This observation serves as a concrete evidence for the big bang theory, which explain the origin of the universe.

Explanation:
Steroid contains a steroidal ring and are devoid of fatty acid chain. The steroidal nucleus is a fused ring consisting of three six membered rings, and a five membered ring.
Examples of steroidal molecules include, cholesterol, steroidal hormones such as estrogen(estradiol) progestrone, testoterone and corticosteroidal hormones such as cortisol, aldosterone and cortisone.
The balanced molecular equation is Na₂S(aq) + ZnSO₄(aq) → Na₂SO₄(aq) + ZnS(s)
The total ionic equation is 2Na⁺(aq) + S²⁻(aq) + Zn²⁺(aq) + SO₄²⁻(aq) → 2Na⁺(aq) + SO₄²⁻(aq) + ZnS(s)
The net ionic equation is S²⁻(aq) + Zn²⁺(aq) → ZnS(s)

what is precipitation?</h3>
Any liquid or frozen water that condenses in the atmosphere and falls to the ground is known as precipitation. Snow, sleet, and rain are just a few of the variations. One of the three main processes that make up the global water cycle is precipitation, along with evaporation and condensation.
Water vapor in the clouds condenses into increasing-sized droplets of water, forming precipitation. Droplets fall to the Earth when they are sufficiently heavy. The water droplets may freeze to produce ice if a cloud is colder, as it would be at higher elevations. Depending on the temperature within the cloud and at the Earth's surface, these ice crystals eventually discharge to the Earth as snow, hail, or rain.
