Moles of OH
which reacted
(mol)

Ch4 is nonpolar and insoluble in water. since all of the hydrogen atoms are evenly spread around the carbon atom even through the c h bond is polar all the poles cancel each other out.

1) according to the law of conservation of mass ,in all chemical reactions total mass is unchanged

The phase where ice changes directly to gas is called sublimation 

The answer is c.  h+  and oh−  react to form water (h2o). i just took the test and i got it right. hope this !
