Answer:
A water molecule is made up of two hydrogen atoms and one oxygen atom.
Explanation:
Answer:
since that's the closest option we have
10.6atm
Explanation:
Since volume is constant
P1/T1 = P2/T1
P1 =8.5atm
T1 = 59.2°C = 332.2k
T2 = 140°C = 413k
P2 = ?
8.5/332.2 = P2/413
0.026 = P2/413
P2 = 0.026 x 413
P2 = 10.74atm
Answer:
Strength
Explanation:
Lattice energy is the energy needed to remove one mole of ionic substance to its gaseous ion.
The lattice energy is used to determine the strength of a substance.
- Lattice energy increases as the size of an ion decreases.
- It decreases as the ion size increases.
- This quantity is often determined using electrostatics method in the laboratory
- The lattice energy is used to break an ionic solid to form a gaseous compound.
Answer:
A chemical reaction is a process in which the chemical bonds of a substance are broken or rearranged. One or more substances are formed with different properties because of this chemical reaction. Examples of chemical reactions are rust, combustion, and oxidation.
Answer:
Benzoic acid, anthracene
Explanation:
If you have a compound with an aqueous layer and organic layer, they can be distinguished by adding distilled water. The aqueous layer increases in size.
Organic products are soluble in organic solvent (organic layer). Benzoic acid, anthracene are both acidic, therefore if you perform an extraction with acidic aqueous solution both would dissolve in the methylene chloride thereby remaining in the organic layer.
