The diagram shows the process of the water cycle on Earth. The heat from the Sun causes water to evaporate: the liquid water turns into water vapor. The water vapor eventually cools in the atmosphere and becomes clouds. These clouds eventually precipitate. Explain how this diagram relates to what you observed in the biome.

The covalent compound acetylene, which is the fuel of the oxyacetylene torch used by welders, has the molecular formula c2h2. the covalent compound benzene, a commercial solvent, has the molecular formula c6h6 each of these covalent compounds contains carbon and hydrogen atoms in a one-to-one ratio. would it be correct to write the chemical formulas of each as ch? explain.

How many moles are in 7.2 x 10^23 carbon molecules? (*round to the nearest hundredth and include the unit "mol c" after your number) question 6 options:
