Is Heating potassium chlorate a chemical or physical change?
Heating anything to a visible change is ALWAYS a chemical change
What are the chemical symbols for iron chloride plus hydrogen?
The symbols for iron chloride plus hydrogen are: FeCl2 + H2.
Is mixing salt water and silver nitrate chemical change or physical change?
Mixing salt water and silver nitrate would result in a chemical change, as a reaction would occur between the compounds to form a precipitate of silver chloride. This new substance has different chemical properties than the original reactants.
Is adding silver nitrate to salt water a chemical change?
Oh, dude, adding silver nitrate to salt water is a chemical change because it forms a solid precipitate of silver chloride. It's like mixing chocolate and peanut butter - two great things coming together to create something new. So yeah, it's totally a chemical change, but don't worry, the salt water won't mind the company.
What is the reaction between acetyl chloride and sodium acetate?
The reaction between acetyl chloride and sodium acetate would likely result in the formation of acetic anhydride and sodium chloride. Acetyl chloride would react with the sodium acetate to form acetic anhydride, along with sodium chloride as a byproduct.
Is Heating potassium chlorate a chemical or physical change?
Heating anything to a visible change is ALWAYS a chemical change
Is heating a chemical or physical change?
Heating a substance can result in either a physical change or a chemical change. A physical change does not alter the substance's composition, such as melting or boiling, while a chemical change leads to the formation of new substances with different properties, such as burning or baking.
Is iron chloride and sodium hydroxide a physical or chemical change?
The reaction between iron (III) chloride and sodium hydroxide is a chemical change as new substances are formed. Iron (III) hydroxide and sodium chloride are produced as a result of the reaction.
When a solution is heated and a gas is formed is that a chemical change?
If there is no chemical reaction occurring in the solution as a result of heating then this scenario constitutes a phase change.
Is mixing iron iii chloride and sodium hydroxide a chemical or physical change?
Mixing iron III chloride and sodium hydroxide would result in a chemical change. The reaction between the two compounds forms iron III hydroxide and sodium chloride, which are new substances with different chemical properties than the original reactants.
When heated to decomposition calcium chloride produces chlorine gas is it physical or chemical?
The production of chlorine gas when calcium chloride is heated to decomposition is a chemical change. This is because a new substance (chlorine gas) with different chemical properties is formed as a result of a chemical reaction taking place between the calcium chloride and heat.
Is heating and cooling are examples of a chemical change?
Heating can be due to a chemical change, for example burning a fuel is in effect a chemical reaction with oxygen. Also some chemical reactions are exothermic, ie they produce heat. Not so many produce cooling, but one is the combination of ice and salt.However heating and cooling happen for other reasons as well, so you can't say they are examples of chemical changes. It is correct to say that some chemical changes result in heating and cooling.
Why Heating zinc oxide is a physical change Why?
It is a physical change. I goes from white, to yellow, back to white.
Is Heating a hydrous salt to obtain an anhydrous salt a chemical or physical change?
if you mean epsom salts (magnesium sulfate) then heating it will result in a decomposition reaction, where magnesium oxide (s) and sulfur trioxide (g) is formed. The decomposition reaction is therefore a chemical change.
Is the formation of salt a chemical or physical change?
The formation of salt is a chemical change because it involves the rearrangement of atoms and the formation of new chemical bonds between sodium and chloride ions. This results in a new substance with different properties from the original sodium and chloride ions.
When hydrogen burns in chlorine gas it is a physical or chemical change?
When hydrogen burns in chlorine gas, it undergoes a chemical change. This is because new substances are formed as a result of the reaction, such as hydrogen chloride. The properties of the starting materials are different from those of the products.
Is heating a wood splinter a chemical change and why?
Heating the wood (and not burning it) would be a physical change. If the wood splinter catches fire and burns, then it is a chemical change because a combustion reaction has taken place and the wood is no longer the same chemical composition. It will turn into carbon dioxide and water, and other materials left over.
