What mass of potassium chloride can be collected at 0.987 atm of pressure and 250 C when 230.6g of KClO3 goes through the following reaction? KClO3 (s) KCl (s) + O2 (g) **unbalanced**

Melting 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.

All forces cause motion? true or false

Achemist reacted 57.50 grams of sodium metal with an excess amount of chlorine gas. the chemical reaction that occurred is shown. na + cl2 → nacl if the percentage yield of the reaction is 86%, what is the actual yield? show your work, including the use of stoichiometric calculations and conversion factors.
