34. For each of the reactions, calculate how many grams of the
product form when 17.8 g of the reactant in color complete-
ly reacts. Assume there is more than enough of the other
reactant.
(a) Ca(s) + Cl2(g) - CaCl,(s)
(b) 2 K(s) + Br(I) — 2 KBr(s)
(c) 4 Cr(s) + 3 0(g) 2 Cr2O3(s)
(d) 2 Sr(s) + O2(g) - 2 Sro(s)

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

the maximum mass of nh3 is nh3 in grams

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
