1. Which two dates from the chart above would have nights with a full moon?

1. Since I don’t have access to the chart you’re referring to, I can't identify which specific dates would have nights with a full moon. Typically, a full moon occurs once a month, so you would need to identify the dates in the chart that correspond with that full moon phase.

2. Yes, on Halloween night 2020, the moon was indeed a full moon, which means that the entire face of the moon visible from Earth was illuminated by the sun. A full moon occurs when the Earth is positioned between the sun and the moon, allowing the sun's light to fully illuminate the moon's surface facing Earth. Therefore, on that night, the moon appeared fully lit and bright in the sky.
