I NEED THE ASNWER ASAP I'M IN A RUSH THX :D

Here you are I really hope this helps you

Explanation:

Changes in the Moon's position as it revolves around the Earth results in more or less of the sunlight reflected form the Moon being visible when observing the Moon from the Earth. This causes the Moon to appear to change shape.

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
