Na2S

Na3n

Explanation:

I just did it

The chemical formulas are aluminum bromide (AlBr₃), magnesium bromide (MgBr₂), sodium sulfide (Na₂S), and the chemical compound formula of the sodium nitride is Na₃N.

Chemical formulas are important to identify the chemical composition of the mixture as they provide important information about the types and numbers of atoms present in a molecule or compound and also predict the properties of a substance, such as its melting point and boiling point. This is useful in industries such as manufacturing, agriculture, etc which has significant importance in the field of medicine, as it helps researchers understand how the human body interacts with the drug.

Hence, the chemical formulas are aluminum bromide (AlBr₃), magnesium bromide (MgBr₂), sodium sulfide (Na₂S), and the chemical compound formula of the sodium nitride is Na₃N.

Answer: cellular membrane: The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.

Explanation:

passive transport Passive transport is a type of membrane transport that does not require energy to move substances across cell membranes. Instead of using cellular energy, like active transport, passive transport relies on the second law of thermodynamics to drive the movement of substances across cell membranes.

It’s something like The lunar phase or Moon phase is the shape of the Moon's directly sunlit portion as viewed from Earth. The lunar phases gradually change over a synodic month as the Moon's orbital positions around Earth and Earth around the Sun shift

Answer with Explanation:

A lunar phase is also known as a "moon phase." This refers to how we see the Moon in different shapes as it is reflected back to Earth. Such reflection depends on the portion of the Moon that is illuminated by the sun. This explains why the amount of moon that we view from Earth changes over time.

It consists of 8 phases: New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Third Quarter and Waning Crescent.
