Nataly [62]3 years ago

Answer:

45) the answer is C.

46) The calculation of quantities in chemical reaction is called Stoichiometry .

47) The phase changed from solid to gas so I think the answer is A.

48) The phase changed from solid to gas as well so I think that the answer is A again.

49) Applying the formula n = m/M, we have n = 1.5 moles, therefore the answer is D.

50) C2H4 + 3O2 -> 2H2O + 2CO2

The answer is C.

51) The answer is C.

52) 2NaHCO3 + CaCl2 -> CaCO3 + H2O + 2NaCl + CO2

Hopefully I got all of them correct.

Need help ASAP!! Full paragraph! Will give Brainliest!!
Amanda [17]

Answer:

All elements in the same group of the periodic table have the same number of valence electrons. This made it possible to compare the valence of the alien elements to the valence of elements from our periodic table, and match the alien elements to the correct group. For example, our group 14 elements all have 4 valence electrons, so the alien element with 4 valence electrons had to be part of group 14 also.
