answer: white fur works as a camouflage against the white snow, allowing polar bears an advantage when hunting for food and hiding from predators
The atoms decay until the nucleus is balanced again
Did you perhaps mean the phase of matter?
If so, then a solution has only one phase of matter: liquid. It is always almost always liquid because solutions are made up of a solvent and a solute and a solvent is always a liquid. Though, some may come in an emulsion form, but still it can be considered as liquid
Answer:
Na Cl ?
Explanation:
None of them but Sodium and Chlorine does make salt i think thats what you meant.
Answer: C) 
Explanation: The <u>Valence</u> <u>Shell</u> <u>Electron</u> <u>Pair</u> <u>Repulsion</u> <u>Model</u> (VSEPR Model) shows bonding and nonbonding electron pairs present in the valence, outermost, shell of an atom connecting to other atoms. It also gives the molecular geometric shape of a molecule.
To determine molecular geometry:
1) Draw Lewis Structure, i.e., a simplified representation of the valence shell electrons;
2) Count the number of electron pairs (count multiple bonds as 1 pair);
3) Arrange electron pairs to minimise repulsion;
4) Position the atoms to minimise the lone pair;
5) Name the molecular geometry from the atom position;
Trigonal planar molecular geometry is a model which molecule's shape is triangular and in one plane. Such molecule has three regions of electron density extending out from the central atom and the repulsion will be at minimum when angle between any two is 120°.
The Lewis structure of each molecule is shown in the attachment.
<u>Analysing each one, it can be concluded that molecule with trigonal planar geometry is </u>
