Nitrous Oxide is heavier than air.
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!! :)
The pH of Magnesium oxide is 10.3, which is slightly alkaline.
Magnesium oxide in fact is soluble in water but very little. it means that if you put magnesium in water and fitrate and repeat this a few times you can realize that you don"t have the same amount that you started with. the reason why magnesium oxide is less soluble in water than other metals oxide, is due to the intramolecualr force within the magnesium oxide compound. In fact, magnesium oxide is very small, and the attaction forces are very strong to be broke apart when reacted with water.
When Magnesium burns, it is actually combining with oxygen in the air to form a new compound, magnesium oxide. If we were to carefully weigh a piece of magnesium before and after burning it, you would see that its weight increased by about one third. For example, if you start with 100 grams of magnesium, after the burn you would end up with about 130 grams of magnesium oxide. The fact that the magnesium oxide you create by burning is powdery, means that it takes up more space (size or volume) than the solid magnesium did.
Magnesium reacts with steam faster than cold water because magnesium needs to burn to get magnesium oxide and to get magnesium oxide there has to be heat and since steam is already heated it doesn't need much time, but the cold water needs time to heat first to react.
You get a grey powder because magnesium is higher up in the reactivity series than Copper - (magnesium is more reactive than copper) therefore when you heat it up there is a displacement reaction. That grey powder is actully magnesium oxide and copper e.g Copper oxide + magnesium = magnesium oxide and copper.
It is a compound.
When magnesium is heated it reacts with oxygen in the air to for Magnesium oxide (MgO) 2Mg + O2 = 2MgO Magnesium oxide is white, so when it is heated, it produces a bright white light.
Magnesium is more reactive than iron. Magnesium reacts more readily with oxygen and water to form compounds like magnesium oxide and magnesium hydroxide compared to iron.
No it does not. Magnesium is more reactive than zinc and so zinccant replace magnesium.
Magnesium oxide is non-flammable, but magnesium can burn. Magnesium oxide Melting Point: 2852 °C, 3125 K, 5166 °F Boiling Point: 3600 °C, 3873 K, 6512 °F Magnesium Melting Point: 923 K, 650 °C, 1202 °F Boiling Point: 1363 K, 1091 °C, 1994 °F
