The elements x and y combine in different ratios to form four different types of compounds: xy, xy₂, xy₃, and xy₄. consider that there is enough of each sample to contain 2 g of x, and the mass of x is estimated to be 2 g and the mass of y is estimated to be 4 g.
arrange the following ratios in order of their increasing value. (the exercise gives me three tabs to put in order from highest to least. these are in the pic)
rank from highest to lowest ratio. to rank items as equivalent, overlap them.
i put xy₄ as highest, then xy₃ in the middle, and xy₂ as lowest. is this order correct? i'm not quite understanding this lesson : // so if i could also get some sort of an explanation, that'd be

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.
