What is the limiting reactant when 5.5 mol of Ni(NO3)3 reacts with10.0 grams of NaOH? Ni(NO3)3 + 3Na(OH) -> Ni(OH)3 + 3NaNO3

a) If you wanted to design an experiment such that the limiting reactant from #5 was still the limiting reactant when it reacted with calcium phosphate, what mass of excess reactant could you use/ would you need? (multiple answers may apply)

One of these occurs (depending on the limiting reactant you chose):

6Na(OH) + Ca3(PO4)2 --> 3 Ca(OH)2 + 2Na3PO4

2Ni(NO3)3 + Ca3(PO4)2 --> 2Ni(PO4) + 3Ca(NO3)2

A5 mole sample of liquid acetone is converted to a gas at 75.0°c. if 628 j are required to raise the temperature of the liquid to the boiling point, 15.600 kj are required to evaporate the liquid, and 712 j are required to raise the final temperature to 75.0°c, what is the total energy required for the conversion?

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.

The standard emf for the cell using the overall cell reaction below is +2.20 v: 2al(s) + 3i2(s) → 2ai3+(aq) + 6i-(aq) the emf generated by the cell when [ai3+] = 3.5 × 10-3 m and [i-] = 0.015 m is v. the standard emf for the cell using the overall cell reaction below is +2.20 v: 2al(s) + 3i2(s) 2ai3+(aq) + 6i-(aq) the emf generated by the cell when [ai3+] = 3.5 × 10-3 m and [i-] = 0.015 m is v. 2.36 2.24 2.21 2.51 2.04
