Litmus solution is generally a purple dye. The solution of Litmus is extracted from lichens. The Litmus solution is used as an indicator to determine the acidic and basic nature of a solution.Lichens plants belonging to the class of Thallophyta. The litmus solution method involves the grinding and crushing of lichens. In order to get the desired litmus solution, such dyes are then introduced to neutral water.
I believe your answer is 40g 15*C I hope that helps.
The law of conservation of mass states that
In any chemical reaction mass is neither created nor destroyed rather it remains conserved
- Mass of reactants=Mass of products
Look the chemical reaction below
Count the mass on both sides and simplify
- It will be 18g and ratio remains one
Answer is no
The chemical reaction between iron and oxygen in the presence of moisture or water produces a new substance, which is the rust (iron oxide). In this case, it shows a chemical property.
