What political party is most closely associated with the opponents of Andrew Jackson and his political party

What are the spectator ions in the reaction between KCl (aq) and AgNO3 (aq)?

Glass of orange juice typically contains around 1.6 g of citric acid in 100 mL. What is the concentration of citric acid in the juice in M? Assume the molecular weight of citric acid is 192.12 g/mol. Give your answer to 3 decimal places.

Coral bleaching is a sign that the coral is doing very well and is healthy.

A reaction Gibbs energy, ΔG, is sometimes not easy to determine experimentally. However, if the chemical reaction is a redox reaction that can be assembled into the form of a voltaic cell, then the Gibbs energy, ΔG, can be measured using just a volt meter! Consider the following redox reaction: 2 NO3− + 8 H+ + 3 Cu → 2 NO + 4 H2O + 3 Cu2+ It is a complicated reaction! You should be happy that you donate need to understand but in order to answer this question. Although it is complicated looking, it can be setup as a voltaic cell, where the voltage, Ecell, is measured to be +0.62 V on a voltmeter. What is the Gibbs energy of the redox reaction above as written, in kJ (to 1 decimal place)? You also need to know that there are 6 electrons involved in this reaction. Use the following to determine ΔG. ΔG = -n F Ecell F = 96,485 Coulombs/mol

Again, remember that your webcam must be pointed so that BOTH hands and your desktop can be clearly seen for the entire duration of the test. If your camera is built-in to your computer, you may tilt is back as necessary to see the screen, but anytime you are working on your paper, your desktop and hands should be visible to the camera.  This test is closed book. The use of any resources including devices, websites or notes, is a violation of academic integrity.  Failure to follow the rules of this test will result in a ZERO on the test.

Give the percent yield when 28.16 g of CO2 are formed from the reaction of 4.000 moles of C8H18 with 8.000 moles of O2.                         2 C8H18 + 25 O2 → 16 CO2 + 18 H2O

Prokaryotes are organisms with nuclei.

Were any states exempt from the Emancipation Proclamation?  If not why not and if so why?
