Is magnesium plus oxygen a chemical or physical change?
The reaction between magnesium and oxygen to form magnesium oxide is a chemical change. This is because new substances with different properties are formed during the reaction.
Is burning magnesium a physical change?
This is a chemical change, like any other burning reaction: magnesium is turned into magnesium oxide by burning reaction with oxygen (from air). 2Mg + O2 --> 2MgO
If you melt magnesium metal is it a chemical change?
Yes, the combustion of magnesium, or anything else for that matter, represents a chemical change. For magnesium, the combustion reaction results in the loss of magnesium and the production of magnesium oxide. Clearly a chemical change.
What is a physical property that magnesium has?
One physical property of magnesium is its silver-white color.
Properties that describe the appearance of matter are known as?
physical
What element has the same physical and chemical properties as magnesium and strontium?
Calcium has similar physical and chemical properties to magnesium and strontium. They all belong to the same group of the periodic table, which means they have similar reactivity and characteristics.
Is magnesium plus oxygen a chemical or physical change?
The reaction between magnesium and oxygen to form magnesium oxide is a chemical change. This is because new substances with different properties are formed during the reaction.
What are the difference between a substance's physical properties and its chemical properties?
Chemical properties involve reacting with another substance. IE: burning of magnesium requires oxygen after which it is no longer magnesium. Physical properties do not. IE: metals are malleable, some very malleable, like copper wire can be bent with your hand. BUT it is still copper wire.
Why is magnesium a metal?
magnesium is not a metal but a reactive metal. scientists have divided all elements into two types of category: metals and non-metals to classify them as they have different chemical and physical properties. magnesium has properties of a metal so it is a metal.
What is an astatide?
An astatide is a binary compound of astatine and another element.
What family of physical properties is magneium in?
Magnesium belongs to the family of alkaline earth metals in the periodic table. It exhibits physical properties such as high strength-to-weight ratio, low density, and strong alkaline reactivity.
What is the chemical formula of ammonium astatide?
I believe the chemical formula for cesium astatide is "CsAt".
What is physical properties of magnesium wire heated?
When magnesium wire is heated, it undergoes several physical changes. Initially, it expands due to increased temperature, which causes the atoms to vibrate more vigorously. As the temperature rises further, magnesium can ignite and burn with a bright white flame, producing magnesium oxide. This combustion alters its physical state, transforming the wire into a powdery ash-like residue.
Is burning a magnesium ribbon a physical change?
Burning a magnesium ribbon is a chemical change because the magnesium reacts with oxygen in the air to form magnesium oxide. This results in a new substance being formed with different chemical properties than the original magnesium ribbon.
What element has the most properties in common with magnesium on the periodic table?
Calcium is the element that has the most properties in common with magnesium on the periodic table. Both elements are in Group 2, known as the alkaline earth metals, and share similar physical and chemical properties such as high reactivity and the ability to form ionic compounds.
Will caesium astatide be soluble in water?
Yes, cesium astatide (CsAt) is expected to be soluble in water due to the high solubility of alkali metal halides in general. Alkali metal halides like cesium chloride are known to be highly soluble in water, and given the similar nature of astatide ion to halide ions, CsAt is likely to exhibit similar solubility properties.
Is burning magnesium a physical change?
This is a chemical change, like any other burning reaction: magnesium is turned into magnesium oxide by burning reaction with oxygen (from air). 2Mg + O2 --> 2MgO
