Which led to the formation of oceans after water on Earth’s surface evaporated?

Explanation:

En tiempos de la formación de la Tierra, el planeta se encontraba a una elevada temperatura, por lo que no le resultaba posible retener ningún tipo de atmósfera. La ausencia de nubes de vapor de agua y océanos en la tierra primigenia era causa directa de su temperatura, ya que el agua se encontraba combinada con los materiales rocosos.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
