What is hard water and how does it affect chemical reactions in chemistry?
Hard water is water that contains high levels of minerals like calcium and magnesium. These minerals can interfere with chemical reactions by forming insoluble compounds with certain chemicals, reducing their effectiveness. This can lead to issues like soap scum formation and reduced efficiency of cleaning products.
Soap scum physical or chemical change?
A chemical change. Soap scum is usually found in 'hard' water areas, where there is a lot of calcium cations (Ca^(2+)). On dissolution of soap in water , the oily anion of soap combines with calcium cation , to form calcium sterate (The Scum).
What is the chemical symbol of ethanol and water?
The chemical symbol for ethanol is C2H5OH. Water does not have a chemical symbol, but its chemical formula is H2O.
Is hard ketchup a physical or chemical change?
Hardening of ketchup is typically a physical change, as it does not involve a change in the chemical composition of the ketchup molecules. It is usually caused by evaporation of water or cooling of the ketchup, which causes it to solidify.
What is the sign for oxygen and water?

When water and concrete mix are combined the material becomes warm and a hard solid forms. is this a physical change or a chemical change?
This is a chemical process: a hydration reaction occur.
When water and concrete mix are combined the material becomes warm and a hard solid forms so Is this a physical change or a chemical change?
The reaction between water and concrete is a chemical change because new substances are formed as a result of the mixing process. In this case, the components of the concrete react with the water to form a new compound that hardens into a solid material through a chemical reaction.
