Linear molecule with two domains
Explanation:
The describe geometry of the substance fits that of a linear molecule with two domains.
This description is based on the VSEPR i.e Valence Shell Electron Pair repulsion(VSEPR) model. It states that if an atom is bonded by two or more kinds of atoms the shape is determined by the geometry of the bonds around the central atom.
The electron domain is the number of lone pairs of electron around an atom.
Here in CO₂:
there are two lone pairs and the oxygen atoms are in a 180° linear shape around the central carbon atom. The bond is made up of two O⇔C structure.

Answer:
the molecular weight of H2SO4 is 98.086g/mole
Answer:
<em>Density = 1.74 gm/mL</em>
Explanation:
Given that:
Mass of piece of Magnesium = 4.80 grams
The volume displaced by this piece = 2.76mL
Let us learn about a property:
Volume of water displaced by a substance when immersed in the water is equal to the Volume of the substance itself.
So, volume of the piece of Magnesium = 2.76 mL
To find:
Density of magnesium = ?
Solution:
Let us have a look at the formula for Density of a Substance:
Density of a substance is given as the ratio of mass of substance and the volume of that mass of substance.
i.e.
Putting the given values:
So, the answer is:
Density of Magnesium = <em>1.74 gm/mL</em>
