Since I can't post pictures in this answer, I will just tell you how to get the answer. For this question, you need to consider, how many centimeters go into 2 meters? Well, since 1 meter equals one hundred centimeters, 2 meters would equal 200 centimeters. And since we need to know how many 10 centimeter long sections there would be, then you need to divide 200 by 10. 200 divided by ten equals 20. So the answer would be 20 sections. The plumber is able to cut 20 sections. I hope that helped!
In the balanced reaction
2 Fe + O₂ → 2 FeO
2 moles of iron (Fe) react with 1 mole of molecular oxygen (O₂) to produce 2 moles of iron oxide (FeO). The ratio of Fe to FeO is 1-to-1, so if one starts with 42.4 mol of Fe, one will end up with the same amount of FeO, 42.4 mol.
Look up the molar mass of Fe and O:
• Fe = 55.845 g/mol
• O = 15.999 g/mol
Then the molar mass of FeO is approximately 71.835 g/mol, and so the mass of 42.4 mol of FeO is
(42.4 mol) × (71.835 g/mol) ≈ 3050 g
YZ = 16. The triangles are congruent. This would be AAS so YZ = 16 because of CPCTC.
