List the following bonds in order of increasing ionic character:
csf, clcl, brcl, sic

Explanation:

We can determine the ionic character of a bond by using the periodic table of elements. We look up the electronegativity of both elements: the bigger the difference of electronegativity between the elements, the bigger the ionic character of the bond is.

With that in mind, in order of increasing ionic character, the answer is:

c- cold periods in earth's history during which glaciers covered much of the surface.

explanation:

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
