Unknown element x is a metal that ionically bonds to sulfur. is the formula, x3s feasible? why or why not? a) it is feasible. the three metallic ions each receive an electron from sulfur. b) no, it is not feasible. sulfur cannot give three electrons to the metal since the sulfide ion has a -2 charge. c) no, it is not feasible. the metallic ion x only has one valence electron and the sulfide ion receives two electrons. d) no, it is not feasible. three metallic ions cannot provide the exact number of electrons that one sulfur needs for the ionic bond.

Next a skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 15 with the horizontal. the rope moves parallel to the slope with a constant speed of 0.69 m/s. the force of the rope does 800 3 of work on the skier as the skier moves a distance of 8.4 m up the incline. (a) if the rope moved with a constant speed of 2.2 m/s how much work would the force of the rope do on the skier as the skler moved a distance of 8.4 m up the incline? at what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.69 m/s and (c) 2.2 m/s?

This is one type of line graph in which the independent variable is time plotted on the x axis and the dependent variable, also numerical, is plotted on the y axis.

Which of the following compounds would be primarily ionic? methane, ch4, ammonia nh3, calcium chloride, cacl2, or carbon dioxide, co2
