Answer: single covalent bond
Explanation: Chlorine is a simple molecule. each chlorine atom can count 8 electrons in its outer shell. with other chlorine atoms. One pair of shared electrons form a single covalent bond.
Answer:
The pH is approximately: 2.1549
Explanation:
pH = - log(0.007)
Answer:
A solution labeled "0.105 M NaOH" would contain 0.105 moles of NaOH in each liter of solution.
Explanation:
The concentration of a solution in Molarity (M) stands for the number of moles of that substance contained in 1 L of solution.
Molarity = Concentration in mol/L = (Number of moles of solute) ÷ (Volume of solution in L)
Molarity = Concentration in mol/L = 0.105 M = 0.105 mol/L
Number of moles of solute = ?
Volume of solution in L = 1 L
0.105 = Number of moles of solute × 1
Number of moles of solute = 0.105 mole
Hence, a solution labeled "0.105 M NaOH" would contain 0.105 moles of NaOH in each liter of solution.
Hope this Helps!!!
Answer:
The answer to your question is below
Explanation:
There are 4 types of chemical reactions:
- Synthesis is when two elements or compounds form only one compound.
- Decomposition is when 1 compound is broken into 2 or more products.
- Single replacement is when one element is replaced by another element.
- Double replacement is when the cations of two compounds are interchanged.
1.- Decomposition 2 Al₂O₃ ⇒ 4 Al + 3O₂
2.- Single replacement Mg + 2HNO₃ ⇒ Mg(NO₃)₂ + H₂
3.- Combustion 2C₆H₆ + 15O₂ ⇒ 12CO₂ + 6H₂O
4.- Synthesis 2Ag + S ⇒ Ag₂S
5.- Double replacement 3Ca(OH)₂ + 2H₃PO₄ ⇒ Ca₃(PO₄)₂ + 6 H₂O
Answer:
Whether the forces of attraction is strong or weak is explained below in details.
Explanation:
There are three distinct kinds of intermolecular forces in expressions of energy. They are (strongest to weakest) dipole-dipole, hydrogen bonding, and Van der Waals' strengths. Intermolecular forces are weak related to intramolecular forces – the energies which endure a molecule collectively. For instance, the covalent bond, including distributing electron sets among atoms, is much more powerful than the forces impersonate among neighboring molecules.
