in a reaction, 15 moles of carbon dioxide are produced from 5 moles of iron (iii) oxide and 15 moles of carbon monoxide. what is the mole ratio of carbon dioxide to carbon monoxide?

15: 5

5: 15

1: 3

1: 1

What is the number of atoms in 3.54 mol s

What is the mass defect of a mole of nuclei with 1.8 x 10^15 j/mol binding energy?

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
