Consider the following unbalanced equation. C3H8(g) + O2(g) → H2O(g) + CO2(g)
When the equation is completely balanced using
smallest whole numbers, the coefficient of o2 is
(1) 5 (2) 2 (3) 3 (4) 7

Phosphorous acid, h3po3(aq) , is a diprotic oxyacid that is an important compound in industry and agriculture. p k a1 p k a2 1.30 6.70 calculate the ph for each of the points in the titration of 50.0 ml of 1.5 m h3po3(aq) 1.5 m h 3 po 3 ( aq ) with 1.5 m koh(aq). 1.5 m koh ( aq ) .
