The unknown concentration of naoh was determined by titration with hcl. the following data was collected:

ml naoh = 34.8 ml

ml of hcl used = 29.6 ml

concentration of hcl = 0.19 m

what is the concentration of the naoh?

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.

What are the first two quantum numbers for the electrons located in subshell 4d? what are the first three quantum numbers for the electrons located in subshell 2s? how many electrons can be held in a sublevel l = 3? how many electrons can be held in the energy level n = 4? how many electrons in an atom can share the quantum numbers n = 4 and l = 3?

If two objects at different te,peraure are in contact with each other what happens to their temperature
