a copper of mass 120g is heated in an enclosure to a temperature of 12.5c. it then taken out bof enclosure and hold in air for a min and dropped carefully into a copper calorimeter of mass 105g containing 200g of water of 20c% the temp of the water rises to 25c. calculate the rate at which heat is boiling from the pieces of copper​

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

explanation:

i guess it’s a and b

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
