Determine the spin state of each complex using the spectrochemical series along with your chemical intuition. Please explainany complexes that may be difficult to determine. You may assume any 6-coordinate complex has octahedral symmetry. For 4-coordinate complex think about if it should be square planar or tetrahedral a. WC12(OH)44- N
b. Co(Py)42+ py is pyridine
c. Pt(H2O)42+
d. Cr(NH3)4(CO)23+

Agroup of students is studying convection current. they fill two identical balloons with the same amount of helium. one balloon is placed in a freezer and the other is in an area with warm air. after 10 minutes, the balloon are released from a height of 1 meter. which of the following to the students most likely observe? a) the warm balloon expands and rises. the cold balloon shrinks and sinks b) the balloon both rise. the cold balloon is larger than the warm balloon c) the cold balloon expands and rises. the warm balloon shrinks and sinks d) the balloon rise at the same rate. both balloons are the same size

When electrolyzing copper (ll) chloride, what reaction takes place at the anode? what reaction takes place at the cathode?

Imagine that twenty i.u.’s of enzyme z were catalyzing the above reaction for one minute, under vmaxconditions, in a 3.00 ml assay volume. the assay is buffered with 20 mm phosphate buffer, ph 7.60. what will the ph be at the end of that one minute?
