PLEASE HELP FOR EXAM I'll give 5 star and brainliest

calculate the new volume if you have 2.00 L of a gas at 0 degrees Celsius, and raise the temp to 23 degrees Celsius.

using V1/T1 =V2/T2

Advice: You must convert the T numbers into degrees K - do not use degrees C. So, 23 C is 296 K.

When you perform this reaction, what could remain at the end of the reaction? check all that apply. excess reactant aqueous copper chloride excess reactant aluminum oxygen product solid copper carbon dioxide product aqueous aluminum chloride water
