17. Copper, Cu, is used in many facets of the roofing and building construction industries. Leading producers of this metal are Chile, United States, Canada, Zambia, and Zaire. To find how many moles of copper is in 1.07 × 1024 atoms of copper, you should

A divide the number of Cu atoms by 6.02 × 1023 particles per mol.

B subtract the number of Cu atoms by 6.02 × 1023 particles per mol.

C add the number of Cu atoms by 6.02 × 1023 particles per mol.

D multiply the number of Cu atoms by 6.02 × 1023 particles per mol.

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)

Rank the following four acids in order of increasing bronsted acidity : h2f+ , ch3oh, (ch3)2oh+ , ch3sh2+

How many liters of oxygen gas, at standardtemperature and pressure, will react with 35.8 grams ofiron metal? 4 fe (s) + 3 o2 (g) → 2 fe2o3 (s)
