Predicting Products Practice Identify the type of chemical reaction, predict the products of the chemical reaction, write the complete chemical equation,
and balance the chemical equation. Use the activity series for single replacement reactions and note the phases of both the
reactants and the products for double replacement reactions using the solubility rules.

How does litmus paper indicate an acid?

How does the viscosity of magma change as magma cools?

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
