3. Sodium tetraborate, Na2B407, is produced when sodium hydroxide neutralizes H3BO3. How much boric acid, H3BO3, is needed (in grams) to
make 150 metric tons of sodium tetraborate? Assume 1 metric ton equals
1000 kg and water is the second product.

Fill in the coefficients that will balance the following reaction: a0cr2(so4)3 + a1agno3 -> a2cr(no3)3 + a3ag2so4

Although respiratory organs vary across different organisms, they all contain respiratory surfaces that have a large surface area and are extremely thin. explain why having an extremely thin respiratory surface with a large surface area is advantageous for the process of gas exchange
