Ionic bonds are made up of a metal and a nonmetal elements while covalent bonds are are made up of two metal. So, you can just look at the periodic table and identify which compounds have two metals and which have one metal and one nonmetal. Also, those compounds with high electronegativity difference are very likely to be ionic while the opposite is covalent. HOWEVER, some compounds can be both covalent and ionic. For instance, if HCI gas is at higher temperatures, then it is ionic while it would be covalent at room temp.
Hope I've helped.

i think its d but im not sure.
Answer/Explanation:
<u>Acids:</u>
Physical ⇒ Sour Taste, Increases the concentration of hydrogen ions when added to water
Chemical ⇒ Corrosive (Burns your skin and breaks down other materials), Forms hydrogen gas when it comes in contact with a metal, Forms salt and water when added to a base
Example: Tomatoes
<u>Bases:</u>
Physical ⇒ Bitter taste ( Never taste or smell a substance unless your parent/guardian tells you that it is okay), Slippery feeling(never touch a substance unless your parent/guardian tell you that is okay)
Chemical ⇒ Increases the concentration of hydroxide ions when added to water, Forms salt and water when added to an acid
Example: Soap, Clorox

Answer and explanation;
-Knowledge of chemistry allows the public to make informed decisions.
-Since chemistry is the basis of everything in life, knowing the basics allows us to make smarter decisions. With a knowledge of chemistry, one can form better opinions about the day’s news. An individual will be able to distinguish the truth from the lies in environmental reporting, and better understand the meaning of a chemical spill.
-One can even better decide what your opinion on public policy should be by using your own knowledge of science rather than trying to figure out which politician or pundit is the least untrustworthy.
Fission is a form of nuclear transmutation<span> because the resulting fragments are not the same </span>element<span> as the original atom. The two nuclei produced are most often of comparable but slightly different sizes, typically with a mass ratio of products of about 3 to 2, for common </span>fissile isotopes.<span>Most fissions are binary fissions (producing two charged fragments), but occasionally (2 to 4 times per 1000 events), </span>three<span> positively charged fragments are produced, in a </span><span>ternary fission</span>
