PLEASE HELP ASAP Volcanic activity during Earth’s formation is responsible for contributing a significant portion of CO2 and H2O to the atmosphere. Explain how volcanoes can change the temperature and composition of Earth’s atmosphere over time. Refer to your experimental data or graph as evidence.

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.

An atom's configuration based on its number of electrons ends at 3p4. another atom has seven more electrons. starting at 3p, what is the remaining configuration? 3p63d34s2 3p43d54s2 3p64s23d3 3p44s23d

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt
