2. Sulfur dioxide (SO2) gets blasted out of volcanoes and reacts with oxygen (O2) in our atmosphere to produce sulfur trioxide (SO3). If 128 grams of sulfur dioxide reacts with
oxygen in the atmosphere and 160 grams of sulfur trioxide (SO3) is produced, how many
grams of oxygen originally reacted?
SO2 + O2= SO3

If a 12-v battery is connected to a circuit that has a current of 3.0 a, what is the total resistance in the circuit? 36 ohms 4 ohms 0.25 ohms

Which other elements contain the same number of outer electrons as sodium

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.
