Answer:
option c
Explanation:
Solution is formed when a solute is dissolved a solvent.
Formation of solution is decided by the interaction between solute and solvent.
When a solute is dissolved, the intermolecular interactions in between solute molecules are broken. And New interactions are formed between solute and solvent.
In order to form solution, the solute-solvent interactions must be stronger than solute-solute and solvent-solvent in interactions.
Therefore, among given the option c is correct.
Answer:
All the members of a group of elements have the same number of valence electrons and similar chemical properties.
Explanation:
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior.
1. An ion is a charged atom. A molecule is a neutrally-charged combination of atoms.
2. A molecule is a combination of atoms. It can consist of atoms from one or more elements. For example, an oxygen molecule comprises two oxygen atoms. A compound is a substance made up of a combination of atoms of different elements. For example, water is a compound of hydrogen and oxygen.
3. An electron dot diagram is a simple way of representing the bond and electronic structure of molecules. A formula is a written representation of the types and numbers of atoms in a molecule.
4. As above...a formula denotes which atoms are in a molecule and how many. For example, H2SO4 tells us there are two hydrogen atoms, one sulfur atom and four oxygen atoms in each molecule of sulfuric acid.
5. An ionic bond is a type of chemical bond that stems from electrostatic attraction between ions with opposite charges. A covalent bond is another type of chemical bond that involves sharing of electrons between atoms in order to achieve a stable electronic structure for the molecule as a whole.
Answer:
The identity does not matter because the variables of Boyle's law do not identify the gas.
Explanation:
The ideal gas law confirms that 22.4 L equals 1 mol.
