The following reaction shows sodium carbonate reacting with calcium hydroxide. Na2CO3 + Ca(OH)2 → 2NaOH + CaCO3

How many grams of NaOH are produced from 20.0 grams of Na2CO3?

(Molar mass of Na = 22.989 g/mol, C = 12.01 g/mol, O = 15.999 g/mol, Ca = 40.078 g/mol, H = 1.008 g/mol) (4 points)

a
12.2 grams

b
15.1 grams

c
24.4 grams

d
30.2 grams

answer is a

explanation:

hurricanes form in warm water

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
