A new solid Ni(II) octahedral complex has been synthesized containing only chloride and ammonia as ligands. When 9.64x10-4 moles of this complex is dissolved into 425.0 mL of the water, you find that 19.22 mL of 0.1000 M HCl is needed to reach a titration endpoint. What is the final formula? (Make sure that your final formula contains the necessary counter ions to make a neutral salt)

calculate the vapor pressure of an aqueous solution at 30 degrees C made from 100 g of sucrose (C12H22O11) and 100g of water
Do all chemical compounds undergo each type of chemical reaction,i.e. synthesis, decomposition, metathesis-precipitation, metathesis-neutralization, redox-single displacement, redox-combustion and can this information be useful to a criminal inves..
prepared in good yield as the exclusive product of hydration of an alkyne with water, SO4 and Hg to form ketone
MnSO4 (aq) is converted to MnO2(s) in a basic medium as oxygen gas is converted to hydroxide ion. In this case, is the sulfate ion a spectator ion
a sample of helium gas initially at 37 degrees celsius, 785 torr and 2.00L was heated to 58.0 degrees celcius while the volume expanded to 3.24L. What is the final pressure in atm.
