Yes silicon can undergo physical and chemical changes.
Yes silcon can undergo chemical reactions but it needs catalyst. You sure are familiar with SiO2. SiO2 is used in coating plates for thin layer chromatography thus serving as the stationary phase.
Copper sulfate dissolving in water is a physical change as no new substance is formed. However, if copper sulfate is heated to decomposition, it would be a chemical change because a new substance is formed.
A physical change is a change where the atoms might get separated but there is no change in it's chemical. It all depends on what you did with the atoms (For example, poisoning something is a physical change), and if the thing itself is edible.
A catalyst doesn't undergo a chemical change during a chemical reaction.
Yes, heating red lead in a test tube is a chemical change. The process of heating causes the red lead to undergo a chemical reaction, leading to a change in its chemical composition. This change is irreversible.
Matter can undergo go both physical and chemical change.
Hg is not a change, it is an element. It can undergo changes, both physical and chemical.
No. It is a chemical change.
Yes silcon can undergo chemical reactions but it needs catalyst. You sure are familiar with SiO2. SiO2 is used in coating plates for thin layer chromatography thus serving as the stationary phase.
Bread is not a change. It is a mixture of substances that can undergo physical and chemical changes.
It is a physical phenomenon.
Magnesium is not a change of any sort. It is a metallic element that can undergo both physical an chemical changes.
if during a change the chemical composition of the reactants change or any new products are formed then the reactant is said to undergo chemical change.if the state, color, phase or any other physical properties of the reactant change without any change the chemical composition of the reactants or formation of any new substances then it is said to undergo physical change
Tuna is not a change, it is a fish commonly eaten as food. Tuna can undergo physical and chemical changes.
Heterogenous mixtures undergo physical change (I THINK)
Initially the only change its location (physical). In the stomach, though, it starts to undergo chemical changes.
Oxidation is a chemical reaction; but a physical modification can also occur.
