If it is a really humid warm day, have you ever noticed that's when all electrical storms occur
1. Solids
- definite volume & shape
- little energy
-vibrate in place
- very incompressible
2. Liquids
- held together yet can still flow
Answer: All of these statements are true
Explanation:
Melting point help us to determine if a mixture is pure or has impurities by the virtues of it melting range..
Answer:
The breaking of the chemical bonds of a storage molecule transfer energy, no what molecule is stored.
Explanation:
Being successful of plants and animals does not necessary depend on the stored molecule but on the energy being transferred during their breaking.
Answer:
The intermolecular forces between CO3^2- and H2O molecules are;
1) London dispersion forces
2) ion-dipole interaction
3) hydrogen bonding
Explanation:
Intermolecular forces are forces of attraction that exits between molecules. These forces are weaker in comparison to the intramolecular forces, such as the covalent or ionic bonds between atoms in a molecule.
Considering CO3^2- and H2O, we must remember that hydrogen bonds occur whenever hydrogen is bonded to a highly electronegative atom such as oxygen. The carbonate ion is a hydrogen bond acceptor.
Also, the London dispersion forces are present in all molecules and is the first intermolecular interaction in molecular substance. Lastly, ion-dipole interactions exists between water and the carbonate ion.
