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.
Is heat produced or absorbed when alkali metals react with water?
Produced, in great abundance!
What are vein deposits usually produced by?

Vein deposits usually produced by what?
hydrothermal solutions
What do you call a solid that forms when two solutions react?
precipitation
What is it called when Solutions are combined to form another solution?
dilution if the solutions do not react with each other. reaction if they do react. Mixing if the two solutions do not dissolve one another (such as a nonpolar solution mixed with a polar solution)

Maria would like to determine how mixing two solutions that chemically react with each other affects the density of the solutions Maria hypothesizes that the solutions will increase in density Maria?
maria is not godd

What two main products are produced when acids react with metal?
a salt and hydrogen gas
What salt solutions would react with lead?
sulphate will react too lead
What is produced when acids and bases react?
A salt is produced when an acid and a base react each other.
What is the gas produced when a base is mixed with carbonate?
Those two kinds of compounds do NOT react at all.
What is precipitation reaction reaction?
A precipitation reaction is one in which two solutions react to form an insoluble solid called a precipitate and a precipitate is an insoluble solid which is formed on mixing certain solutions.
What gas is produced when potassium hydroxide and calcium carbonate are mixed?
Those two compounds do NOT react at all.
What is produced after the reaction between vinegar and baking soda?
The combination of the two becomes a salute and no longer can react.
