Is adding calcium to water a chemical property or chemical change?
Calcium reacting with water is a chemical change.
Formation of ethanol from glucose by yeast a chemical or physical change?
A chemical change
When Ethanol boils is that a chemical change or chemical property?
neither. it is a change of state.
When ethanol condenses and from the gaseous phase into the liquid phase is this a physical change or chemical change?
physical change- the composition of the ethanol is not effected
Is burned ethanol a physical or chemical change?
Burning anything (a liquid or a solid) is a chemical change and the reaction is known as a combustion reaction.
Grape juice turns to wine chemical or physical change?
Grape juice contains mostly glucose (C6H12O6) and wine also has ethanol (C2H5OH). The ethanol is produced by fermentation of glucose by yeast cells. This is a chemical change.
Is ethanol boiling a chemical reaction?
no, boiling is a physical change
When ethanol is burnt and converted into carbon dioxide and water is that a chemical or physical change?
chemical
Is calcium in water a physical or chemical change?
Adding calcium to water results in a chemical change because the calcium and the water that react are combined to form a distinct new substance, calcium hydroxide, that did not exist in either the calcium or the water before their reaction.
Is The colorless liquid ethanol burns in air a physical or chemical property?
ethanol is a type of alcohol, in the oxygenated hydrocarbon class of compounds. when it combines rapidly with oxygen in a combustion reaction, the ethanol is used up, and with oxygen forms carbon dioxide and water. ethanol is quite literally gone, it is broken down and reformed into new products, which is the definition of a chemical reaction.
Is the reaction between Sodium acetate and water a chemical reaction?
No, it is simply the water dissolving the sodium acetate, which is a physical change. There is a physical change when you introduce a seed crystal to the sodium acetate as the bonds in the chemical become different to form a solid. By adding water, you are just dissolving it and then allowing it to become supersaturated through heating.
Is developing film a chemical or physical change?
chemical change :-)
