Here
are the answers for the two ions:
<span>1.
For K+, this would be the answer: Zeff
= 19 - (0.35(7) + 0.85(8) +2) = 7.75</span>
2. For CI-, Zeff = 17 - (0.35(7) + 0.85(8) +2) = 5.75
I am hoping that these answers have satisfied your queries and
it will be able to help you.
I am unsure if this is correct, but this might be the whole section:
- The top of the syringe is a circle. You need to compute its area for use in later computations of pressure values. Start by using a ruler to measure the diameter. Estimate to the nearest 0.01 cm. <em>Answer: </em><em>3.60 </em><em>cm</em>
- Divide by two to find the radius. Maintain significant figures. <em>Answer: </em><em>1.80 </em><em>cm</em>
- Substitute the radius into the formula A = πr² to find the area of the top of the syringe. Maintain significant figures. <em>Answer: </em><em>10.2 </em><em>cm²</em>
a method of procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses.
I’m pretty one of the answers is water, but I don’t know if there is more
