Please answer this question for me Potassium sulphate can be prepared by the reaction between dilute sulphuric acid and
potassium carbonate.
H 2 SO 4 + K 2 CO 3 → K 2 SO 4 + CO 2 + H 2 O
Calculate the mass of potassium sulphate that can be prepared from 3.45 g of potassium
carbonate.

Freezing and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
