Answer:

C. H2O (l) --> H2O (g)

Explanation:

Hello,

In this case, we need to remember that processes absorbing energy are those that have positive heat, it means, process that obtain energy from a certain source. In such a way, processes that need energy, in terms of phase chance are fusion, sublimation and evaporation, which are the change from solid to liquid, solid to gas and liquid to gas respectively. Therefore, for the given options, we can see that C. H2O (l) --> H2O (g) accounts for an evaporation process which actually absorbs energy.

Best regards.

which molecules show an appropriate number of bonds around each carbon atom? select the three that apply.
iren2701 [21]

The appropriate number of bonds around each carbon atom are four covalent bonds

Please note that carbon has four valence electrons in its outermost shell

<h3>What is an element?</h3>

An element is a substance which cannot be split into simpler forms by an ordinary chemical process. This simply goes to say that elements are substances which cannot be decomposed into simpler substances by ordinary chemical reactions.

An atom is the smallest unit or part of an element which can take part in a chemical reaction.

On a general note, elements are classified as thus:

  • Metals, non-metal, and metalloid.

  • The extreme left side elements in the periodic table are metals, for example, aluminum, sodium, calcium, caesium, etc.

  • However, elements on the right side are generally referred to as non-metals, carbon, chlorine, oxygen,

So therefore, the appropriate number of bonds around each carbon atom are four covalent bonds

Complete question:

What is the appropriate number of bonds around each carbon atom?
