Which of the following is an appropriate unit to measure large distances across the solar system? astronomical unit meter square mile year

Distances in space could be measured in common units of length, such as miles or kilometers. But measuring such large distances in these common units creates some pretty big numbers. It's easier to measure distances in two alternate units of distance- light years and astronomical units.

(please rate brainliest and have a blessed day )

The correct answer is Astronomical Unit.

Explanation:

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
