Is heat produced when two liquids are mixed a physical change?
No and yes. If the two liquids do not react chemically then its a physical change, called the enthalpy of mixing, heat of mixing, which can be exothermic or endothermic. If the two liquids react then the heat produced would be chemical.
What type of double displacement reaction may not produce a visible product?
A reaction where the products formed are liquids in an aqueous solution.
When two liquids are mixed together and a new solids is form which is called?
This is a precipitation reaction.
What causes an increase in the rate of a chemical reaction between 2 liquids?
Increasing the temperature will increase the reaction rate, as will finding a suitable catalyst.
Why are alkane called olefins?
Alkenes are also called OLEFINS because they form oily liquids on reaction with chlorine gas.
Hopkin's cole test reaction?
Produces a Purple ring at the point of contact of the two liquids. :)
What is the general name for a solid produced in a chemical reaction that turns a solution cloudy?
Reaction involving liquids and aqueous solutions can have solid products. These products are known as precipitates. Precipitate reactions have important uses in chemistry and industry.
What forms can reaction products take?
Products of a chemical reaction are solids, liquids or gaseous.
How does surface area of an object affect gravity?
increasing the surface area of reactants in a solid form the speed of reaction is increased the contact between the solid reactants or liquids and gas.
Who was a physician and alchemist who produced distilled liquids?
Paracelsus
Physician and alchemist who produced distilled liquids?
Paracelsus

When two liquids react to form a solid it is called an?
This is a reaction of precipitation.
When you mix 2 liquids and it is warm to touch is it a chemical or physical change?
Can be both or either. 1. When mixed, without chemical reaction, liquids can take or release heat; it is a physical phenomenon. 2. But mixed liquids can react and this chemical reaction can also release heat.
What type of double displacement reaction may not produce a visible product?
A reaction where the products formed are liquids in an aqueous solution.
What is an insoluble product that forms from the reaction of two liquids?
An insoluble product that forms from the reaction of two liquid solutions is called a precipitate.
How do different liquids absorb differently?
the chemicals in the paper towels absorb by creating a chemical reaction with the different materials and in turn soak up the liquids:)
