Why does copper sulfate solution turn clear and magnesium develop a copper coating?
Redox! The magnesium is reducing the copper while the copper is oxidizing the magnesium. In other words, magnesium is giving electrons to the copper to bring the copper back to its metallic form while the magnesium is leaving the metal to be part of the solution as magnesium sulfate, which is colorless.
What did William Crookes conclude from his experiment?
Priestley and Lavoisier discovered oxygen. I think they burned magnesium and it got heavier. The phlogiston theory (the theory that people believed about burning and combustion) could not answer this so they had discovered something. We now know that oxygen from the air is "extracted" when the magnesium is burned. the oxygen then combines with the magnesium and form magnesium oxide. So if you started with 24g of magnesium and burned it, you would end up with about 40g of magnesium oxide.
How many fluoride ions will combine with magnesium to form magnesium fluoride?
MgF2 Two ions of fluorine.yup flouride 1 type the type that makes you a stupid slave. poisin. by product of left over metal by product . dont accept its good for your teeth. its not eat an aluminum can see how that feels same stuff metal ios deadly to humans. here me now!
Why is magnesium oxide heavier than magnesium?
Magnesium Oxide increases in mass because it is made of oxygen AND magnesium, and the symbol equation explains that 2MG (2 magnesium) + O2( 2 oxygen) makes 2MGO (2 Magnesium Oxide) because oxygen is a molecule as the 2 shows that for oxygen it is made up of 2 atoms, and to balance the equation magnesium must be 2 too, making 2 Magnesium Oxide ,this shows the mass increases as oxygen is ADDED to magnesium, thus making it heavier and an increase in mass. Ta-Da just amazing chemistry logic!! :)
How many kg minus 925 g equals 1075?
To solve this equation, convert 1075 to grams, which is 1075g. Then, convert kg to grams for the subtraction: 1 kg = 1000 g. Now, subtract 1075g - 925g which equals 150g.
How many atomes of each element are in a formula unit of magnesium phosphate?
If you balance the charges of the magnesium ion and the phosphate polyatomic ion, you get a formula of Mg3(PO4)2. Now count 'em up: there are 3 magnesiums, 2 phosphrous, and 8 oxygens. (watch those parentheses!)
If you have 2000 pets and you take away 3000 how many do you have now?
none. unless you can get minus pets which would be -1000!
What does a minus balance on acredit card mean?
If your credit (not debit) card has a negative balance on your statement, then there is an overpayment (you paid more than you owe). So now they owe you money. This is usually applied towards future charges.
How many Zoroastrians are left today?
Today the number of of Zoroastrians is dwindling fast . In India it is now minus 3 percent only.
What are the latest updates on the Jordan Peterson charges?
As of now, there are no recent updates on any charges against Jordan Peterson.
Can a 17-year-old girl whose abuse was many years ago and abuser's charges lain 4 years ago get a restraining order against her brotherabuser NOW after the charges were lain?
Of course Of course Of course
What is ten and three eighths minus five and one fourth?
Ten minus five is 5. Now to the fractions, change one fourth to two eighth and u have a common denominator. Now three minus two is 1 so u have an answer of 5 and 1/8.
How do magnesium ions get there charge?
An atom of magnesium has '12' protons in its nucleus. '12+ '. It also has '12' electrons in energy shells around the nucleus. '12-' . These 12 electrons are arranged as 2 electrons in the inner most shell to the nucleus, then 8 electrons in the next outer shell, and finally 2 electrons in the outermost shell. For a magnesium atom to become a magnesium ion, it MUST lose 2 electrons. These two electrons are lost from the outer most energy shell, because they are furthest away from the nucleus. So the charges are;_ Mg(atom ; 12+ & 12- = 0 (No charge) Mg(ion) ; 12+ & 10- = 2+ (charge) because there are now 12 pluses compared to 10 minuses. +12 - 10 = +2 (A little sum) Hence the magnesium ion is described as 'Mg^(2+)'. NB It is an atom when neutrally (0) charged It is an ION when it carries any charge.

What is the material used in mag wheels?
There are many materials that mag wheels are built with. They used to be made with magnesium, but are now made with stronger materials like aluminum alloys and plastic.
