Magnesium

Hydrogen chloride has a covalent bond.

no. it only has ionic as far as i know.

Magnesium iodide is more covalent than magnesium chloride because iodine is a larger atom with more electron-electron repulsion between its electrons, making it easier for iodine to share electrons with magnesium in a covalent bond. This results in a more even sharing of electrons between magnesium and iodine, leading to a more covalent character in magnesium iodide compared to magnesium chloride.

Magnesium is found in chlorophyll and this kind of pigment have a porphyrin ring associated with the protein.

Mg has 2 valence electrons.

Mg-24

No. This is a redox question. It is asking whether the reaction will occur spontaneously. In order for Mg+2 to spontaneously oxidize Cu(s), Mg+2 needs to have a higher reduction potential (the tendency to be reduced) than Cu+2. Check a redox table to see:

Mg2+ + 2 e− --> Mg(s) E° = −2.372

Cu2+ + 2 e− --> Cu(s) E° = +0.340 (More favorable reaction)

Cu2+ has a higher reduction potential, meaning Mg2+ will not oxidize Cu(s).

Because it burns readily and with a bright flame.

If you have pure magnesium, then the two atoms that compose the substance are going to be magnesium atoms. Magnesium is an element, a pure substance composed of all the atoms of the same kind. It is not to be confused with a compound which is made up of two or more atoms of different elements.

No - it is non-renewable

The combustion of magnesium in air is a chemical reaction.

Milk of magnesia is an aqueous suspension of magnesium hydroxide, Mg(OH)2. Each formula unit of magnesium hydroxide contains 5 atoms (one magnesium, two oxygen, two hydrogen).

To give milk of magnesia to a cat, first consult your veterinarian to ensure it's appropriate for your cat's condition and determine the correct dosage. You can administer it using a syringe (without a needle) or a dropper, gently placing it in the side of the cat's mouth to encourage swallowing. Be sure to do this slowly to avoid choking and stress. Always monitor your cat for any adverse reactions after giving the medication.

Believe it or not, aluminum is technically more reactive than iron. However, when aluminum is exposed to air, it almost instantly forms a microscopic layer of aluminum oxide (Al2O3) which protects the rest of the aluminum from any further reaction. Iron doesn't do this, and therefore corrodes unevenly, making it unsuitable for certain applications.

Sulphur dioxide is a covalent compound with a v-shaped structure. Because of this, the molecule is polar and can bond to other molecules due to permanent dipoles, which are relatively strong bonds. Magnesium oxide, on the other hand, is an ionic compound that forms an ionic lattice - due to the attraction between the positive Mg and negative O ions. Because of this, there are strong intermolecular bonds that hold the molecules more tightly together than permanent dipole and so more energy is required to break them than in SO2

Mg + H2SO4 → MgSO4 + H2↑
Magnesium(s) + Sulfuric Acid(aq) → Magnesium sulfate(aq) + Hydrogen(g)

Many metals will react with acids to produce hydrogen, so they too produce hydrogen with sulfuric acid. The hydrogen will be produced from the protons creacted by the acid, and the remainder will become a salt (in aqueous solution) with the metal. If you boil away the remaining acid and water you would be left with crystals of magnesium sulphate. Without removing the water, the magnesium will still be dissolved, and be ionized: Mg(s) + H2SO4(aq) → Mg+2(aq) + SO4-2(aq) + H2(g)

In accordance with Coulomb's Law, the positively charged magnesium ions attract the negatively charged oxygen atoms, and they form an alternating lattice. You never get two magnesium or two oxygen next to each other, because they repel each other; you get alternating magnesium and oxygen.

Yes, magnesium is relatively expensive.

The reasons being because magnesium is a very large commercial market commodity compared to the abundance of magnesium ore in certain geographic countries/locations.

Magnesium is also very difficult to mine, because it is very reactive and therefore harder to separate from its other compounds, which is reflected in the price of the metal.

magnesium + dilute acid=magnesium dilute hydroxide and hydrogen

I believe it is because they don't want to bond. They are both metals and have a positive charge; they repel each other. This is just my guess. If you heat both of the pure substances up in an oxygen rich environment you may get a bright surprise though. ~James

On burning in air, magnesium produces a brilliant white light. they are highly flammable in their pure form when molten or in powder or ribbon form. Burning or molten magnesium metal reacts violently with water. When working with powdered magnesium, safety glasses with welding eye protection are employed, because the bright white light produced by burning magnesium contains ultraviolet light that can permanently damage the retinas of the eyes.

Monovalent sodium and pottasium ions and divalent magnesium and calcium ions are found in large proportions in biological fluids. These ions perform important biological functions such as maintainance of ion balance and nerve impulse conduction.

The chemical reaction equation would be Mg + CO2 + O -> ?.
