The Parker Solar Probe is on its way to the Sun. It is the fastest vehicle humans have built. It will reach a speed of 4.3 x 10^5 miles per hour. At that speed how long would it take to reach the center of our galaxy? Assume straight-line flight from Earth. The earth is 2.5 x 10^4 light years from the center of the Milky Way galaxy. A light year is 5.879 x 10^12 miles. A year is 365.25 days.

Which is a difference between molecular compounds and ionic compounds? select the correct answer below: question 5 options: molecular compounds typically form between a metal and a nonmetal, while ionic compounds typically form between nonmetals. molecular compounds result from the transfer of electrons between atoms to form ions, while ionic compounds result from the sharing of electrons between neutral atoms. molecular compounds are formed of discrete, neutral molecules, while ionic compounds are formed of large repeating arrays of opposite charges. molecular compounds have high melting points and high boiling points, while ionic
