Answer:
Covalent bonds involve the sharing of electron pairs between atoms. Electron pairs shared between atoms of equal or very similar electronegativity constitute a nonpolar covalent bond (e.g., H–H or C–H), while electrons shared between atoms of unequal electronegativity constitute a polar covalent bond (e.g., H–O).
Explanation:
make or become hot or warm is heating.
cooling is to become colder or cool down from a higher temp.
Strong electrolytes by definition are those compounds that completely dissociates into their component ions when dissolved in water. The chemical formula for the zinc fluoride is,
ZnF2
This means that each formula unit is composed of one atom of zinc and 2 atoms of fluoride. The ions comprising the unit are Zn²⁺ and F⁻. The dissociation is as shown below,
ZnF₂ --> Zn²⁺ + 2F⁻
When dissolved in water it is expected that the compound dissociates into three different ions, one Zn²⁺ and two F⁻.
The overall reaction order is 2, because you add the orders of the individual components, which each are 1.
For CO2 there is one atom of carbon and two atoms of oxygen. For H2O, there is one atom of oxyegen and two atoms of hydrogen. A moleclue can Be made of only one type of atom
