Which of the following represents a solution? * 2 points
NaCl (s)
HCl (aq)
H2O (g)
HBr(g)

units of G.

Explanation:Milk of magnesia, a suspension of Mg(OH)2

in water, reacts with stomach acid (HCl) in a

neutralization reaction.

Mg(OH)2(s) + 2HCl(aq) −!

2H2O(l) +MgCl2(aq)

What mass of MgCl2 will be produced if

4.55 g of Mg(OH)2 reacts?

Answer in units of g.

021 (part 2 of 2) 10.0 points

What mass of HCl is required to completely

react with 4.55 g of Mg(OH)2?

passing a magnet thought the

mixture , because iron gets attracted to magnet .

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.
