Scientists discover two new elements, element a and element x, and are able to determine their atomic mass. element a has an atomic mass of 17 amu element x has an atomic mass of 76 amu. these elements combine to form a compound with the following formula: ax3. determine the molar mass of this compound.
a.93 g/mol
b.98 g/mol
c.110 g/mol
d.245 g/mol
e.262 g/mol

An atom of which element reacts with an atom of hydrogen to form a bond with the greatest degree of polarity ?

Which of the following warnings would an agricultural chemist tell a farmer who wants to recycle his or her own ammonia? recycling ammonia is a difficult process that sometimes takes weeks. recycling ammonia requires a degree in biochemistry or a related field. recycling ammonia can be harmful because it is highly flammable and toxic. recycling ammonia costs too much money considering the price of the necessary chemicals.

Why is it important for scientists to review and repeat the work of other scientists? 1.a scientific theory must be tested three times before it is proven. 2.the scientific method only applies to repeated experiments. 3.an experiment may have had errors that the scientists didn't recognize. 4.the results of individual scientists may be influenced by bias. 5.an experiment must be performed twice before the data can be analyzed.
