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.
Answer: It depends on the element.
Explanation: Every element has a different amount of protons in its nucleus. It is the same as its atomic number on the periodic table. For example: Hydrogen has an atomic number of 1 because it has 1 proton in its nucleus, Helium has 2, Carbon has 6, Platnium has 78, and so on...
Claim is : chemical reactions are smaller
Answer:a) 2C4H10 + 13O2 —> 8CO2 + 10H2O. Oxidation reaction
b) 8 (4 moles CO2 per mole butane)
Explanation:
could be written C4H10 + 6 1/2 O2 —> 4CO2 + 5H2O
Answer:
Balanced Chemical equation:
3Mg(s) + 2FeCl₃(s) → 2Fe(s) + 3MgCl₂(s)
Explanation:
Chemical equation:
Mg(s) + FeCl₃(s) → Fe(s) + MgCl₂(s)
Balanced Chemical equation:
3Mg(s) + 2FeCl₃(s) → 2Fe(s) + 3MgCl₂(s)
Solid magnesium react with solid iron(III) chloride and produce solid iron and magnesium chloride.
The oxidation state of iron changed from +3 to zero and that of magnesium is from zero to +2.
<em>Coefficient with reactant and product:</em>
Mg(s) 3
FeCl₃(s) 2
Fe(s) 2
MgCl₂ 3
