As many studies have shown that men have faster reflexes then woman, many woman can have better reflexes then men. It just depends on your genes and dna and all the things that make you be good at things.
Mg (magnesium) reacts with acids and Produces magnesium salt and hydrogen gas as the products.
Followings are some balanced reactions of Mg with acids.
Mg(s) + H₂SO₄(aq) → MgSO₄(aq) + H₂(g)
Mg(s) + 2HCl(aq) → MgCl₂(aq) + H₂(g)
Mg(s) + 2HNO₃(aq) → Mg(NO₃)₂(aq) + H₂(g)
Answer:
A. steel spoon
Explanation:
A steel spoon will get hot the quickest from the different given spoon. This is because steel is predominantly made up of a metal which shows metallic properties such as heat conduction.
- Metals have low specific heat capacity which is the amount of head needed to raise 1g of a substance by 1°C.
- By so doing, metals will conduct heat at a very fast rate.
- The delocalized electron around the central nucleus plays very important role.
Other properties originating from metallic bonds are ductility, malleability, luster etc.
Answer:
The molar mass of:
Helium = 4.00 g/mol
Potassium = 39.0983 g/mol
Manganese = 54.94 g/mol.
Boron = 10.81 g / mol
Explanation:
Helium = 4.00 g/mol
Potassium = 39.0983 g/mol
Manganese = 54.94 g/mol.
Boron = 10.81 g / mol
