Answer: 3.37x10^23 atoms
Explanation:
1mole of Fe contains 6.02x10^23 atoms.
0.56mol of Fe will contain = 0.56x6.02x10^23 = 3.37x10^23 atoms
Answer:
B. The reactants form additional unexpected products.
Explanation:
Answer: In order for reflection to occur, the wave must “bounce off” an object
Explanation: For example if your looking in the mirror the waves are bouncing off the mirror to reflect your image
They have a low boiling point because of weak intermolecular forces. They
Explanation:
Covalent compounds are compounds that are known to have weak intermolecular forces and hence low boiling point.
Covalent bonds are bond formed between two or more atoms having zero or very small electronegativity difference. Such bonds exists between molecules of non-metals.
Here are some properties of covalent bonds;
- They are gases or volatile liquids or low melting point solids
- Most of them are insoluble in polar solvents or water but they are generally soluble in non-polar organic solvents.
- They are mainly non-conductors.

Answer:
Boron and Aluminium
Explanation:
Boron and Aluminium are present in Group 13 of the modern periodic table. Group 13 (IUPAC System) can also be referred to as Group III-A. Logically, Boron and Aluminum can't be placed alongwith elements such as Yttrium as they don't exhibit properties of a transition metal.
