A binary compound is a compound that contain two different chemical elements in it. These compounds may be molecular or may also exist in other forms such as solid. In this case Barium and Beryllium are not binary compounds since they are independent elements, Calcium hydroxide is also not a binary compound since it has more than two chemical elements. Therefore,carbon dioxide is the binary compound since it contains two chemical elements ( carbon and oxygen)
Answer:
0.44 m is the molality
Explanation:
Molality means mol of solute in 1kg of solvent.
Solute → CdBr₂
Solvent → H₂O
Mass / Molar mass = 45.38 g / 272.21 g/m = 0.167 moles
1 g = 1x10⁻³ kg
375 g = 0.375 kg
0.167 m/0.375 kg = 0.44 m
The lone pairs on the oxygen in the following compound are best described as: <u>one localized and one delocalized</u>
<h3>Lone pair electron</h3>
A lone pair electron is valence shell electron pair associated with one atom, and not part of a covalent bond.
Within the context of this question, the oxygen atom of water for instance has two lone pair of which one of them is localized and other one is delocalized

Mixture: matter than is composed of two or more substances that can be separated by physical means (ex; let's say you have a jar of red and blue marbles. this is a mixture. You can separate the colors with your hands (physical means.))
Compound: a substance in which two or more atoms are chemically combined in a fixed proportion (ex: water is a compound that consists of the element hydrogen and the element oxygen).
