Which best describes subduction? when two crustal plates collide to form a volcano when two crustal plates pull apart to form a chasm when a crustal plate is forced below another plate when a crustal plate fuses with another plate?

given the reactants, h2so4 and koh, we are asked to determine the product(s) of the reaction. since h2so4 is an acid and koh is a base. this is a neutralization reaction, thus, the products are salt and water. 

so, h+ from h2so4 will react with oh- from koh forming h2o. k+ will also react with so4 2- forming k2so4. therefore, the balanced reaction will be:

h2so4 + 2koh > k2so4 + 2h2o

"the periodic table is arranged in order of atomic number."
