a. a sperm and egg cell are formed during meiosis
b. the parent cell splits into two identical cells
c. the sperm and egg join, forming a new cell
d. the sperm are present

Consider the following reactions. (note: (s) = solid, (l) = liquid, and (g) = gas.) mg(s) + ½o2(g) → mgo(s) + 146 kcal/mole h2(g) + ½o2(g) → h2o(g), δh = -57.82 kcal/mole what type of reaction is represented by the previous two examples?

3) in peaches, [oh]=3.16x10-11 m a) find [h+ ] b) what is the ph? c) is the solution acidic, basic, or neutral?

Which of these have the same number of particles as 1 mole of water h2o
