Earth’s fresh water can be found in bodies of water that provide people with drinking water and recreational sites. rivers, lakes, streams, and wetlands. These also play a role in maintaining a healthy ecosystem. You explored these valuable systems and their importance in the world in lesson 2.14, however do you recall where MOST of the fresh water is located?

Question 1 options:

The Red Sea between Africa and Asia

frozen in glaciers and ice caps

South America's Amazon River

The Great Lakes between the United States and Canada

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms

the dependant variable is spilled water

the independent is the heat

i don,t know so just answer mine
