Select all that are true for a titration of 0.20 m khp with 0.20 m hcl as the titrant as compared to your titration with 0.20 m naoh as the titrant in the lab. (select all that apply.)
1. the equivalence volume would be the same.
2. the ph at the equivalence point would be the same.
3. phenolphthalein would be an appropriate indicator.
4. the initial ph would be the same.
5. the ph at the midpoint would be the same

You are performing an experiment in a lab to attempt a new method of producing pure elements from compounds. the only problem is that you do not know what element will form. by your previous calculations you know that you will have 6.3 moles of product. when it is complete, you weigh it and determine you have 604.4 grams. what element have you produced?

Achemist is studying the following equilibirum, which has the given equilibrium constant at a certain temperature: 2 no(g) + cl2(g) < => 2 nocl(g) kp = 2 x 10^(-6)he fills a reaction vessel at this temperature with 13. atm of nitrogen monoxide gas and 12. atm of chlorine gas. use this data to answer the questions: a. can you predict the equilibrium pressure of noci, using only the tools available to you within aleks? y/nb. if you said yes, then enter the equilibrium pressure of nocl at right. round your answer to 1 significant digit.
