Draw an electron dot diagram for BaCl2. Explain how your diagram shows that all atoms in the compound are stable.
note; I already have the dot diagram drawn, I just need help with the last part.

19) Sound travels fastest through A)space. B)cool air. C)warm air. D)a metal spoon.

Which statement is TRUE?Question 2 options:Light waves always travel at a constant speed, but sound waves do not. Waves travel at different speeds through different materials. Light waves and sound waves travel at the same constant speed. Wave speed depends on the amplitude of the wave.

The velocity is 60 m/S at an angle of 42 degrees above from the horizontal, the cliff is 150m above sea level. Compare qualitatively the magnitude of the projectiles initial velocity (u) with its final velocity (v). Explain your answer

kiku And Alex are wearing rollerskates Kiku is right behind Alex and both skaters are standing still Alex weighs more than Kiku if Kiku gives Alex a forward push which of the following will be true after the push assume that this is a closed system and friction can be ignored
