there are 8 moon phases.
They are - First quarter, waxing crescent, new, waning crescent, third quarter, Waning gibbous, full, and waxing gibbous
The answer is group 1A.
In the ionic compound formula X₂SO₄, SO₄ has a -2 charge. Hence to balance this -2 charge of SO₄, X must have a +1 charge.
Group 1A elements form X⁺ type of ions because they are metals. So, they have the tendency to lose electrons.
Hence, X must belong to the 1A group.
Ionic Compounds-
- Ionic compounds are formed by the electrostatic attraction between the anions and the cations.
- Cations are positively charged ions that are formed due to the loss of electrons.
- And the anions are negatively charged ions that are formed due to the gain of electrons.
- Due to this, they have opposite charges and form bonds known as Ionic Bond.

Answer:
1.10 g/mL
Explanation:
The amount of volume an object displaces is the amount of volume that object takes up.
7.87 - 1.67 = 6.2
The object has a volume of 6.2 mL.
You have the mass (6.82 g) and the volume (6.2 mL). Divide the two value to find the density.
(6.82 g)/(6.2 mL) = 1.10 g/mL
The density of the object is 1.10 g/mL.
