With some value of mixture co and o2 density by hydrogen is 15 . when reaction begun some time later density by hydrogen of the new mixture become 18.75. find volume portion (%) of co2 in the end.

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.
