What type of reation does Na + F2 --> NaF have (as in synthesis reaction, replacement reaction, and decomposition reactionpick from those 3)

answer; /// the amount of material dissolved in a measure of liquid(concentration) the above statement is (true); /// good luck

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
