Calculate the number of moles of carbon atoms present in 1.7 g of ethanol (C2H60). Answer in units of mol. (Please show the steps to working this out, thank you!)​

In which situation can a mixture always be called a solution

Freezing 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.

Use the periodic table to find the molar mass of each element. molar mass h = g/mol molar mass s = g/mol molar mass o = g/mol
