The reaction yield is 94.4% and there are 4.73 g of magnesium with 1.83 g of water in the reaction. Mg (24 amu): H (1 amu): 0 (16 amu):
Mg(s) + 2H20 (1) >Mg(OH)2 (s) + H2(g)
Blank 1 how many moles of Mg in 4.73 g Mg?
Blank 2 how many moles of H20 in 1.83 g H2O?
Blank 3 which is the limiting molecule?
Blank 4 what mass in grams of hydrogen is produced?

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.

(b) which contains higher levels of vitamin b, oranges or spinach?

explanation:

you can eliminate a, c, and d because they are questions based on opinions.

the answer is c.the valence of the atoms combine .
