Anna stated that ionic compounds have high melting points and low boiling points. She said that this demonstrates that ionic compounds have strong bonds because a lot of energy is needed to break the electrical forces that hold the bonds together. Which statement best describes Anna’s error?

Strong electrical forces will make ionic compounds have high boiling points.
Strong electrical forces will make ionic compounds have weak bonds.
A low amount of energy is needed to break the bonds in ionic compounds.
Gravitational forces hold the bonds together in ionic compounds.

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 740 n/m. it is initially at rest on an inclined plane that is at an angle of theta= 26 with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is uk = 0.17. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. the block's initial mechanical energy is 9.472 j.b. if the spring pushes the block up the incline, what distance l in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
