Q. What is the mass in grams of one mole of any substance know as
A. Molar Mass
Answer:
Non-equilibrium thermodynamics is a branch of thermodynamics that deals with physical systems that are not in thermodynamic equilibrium but can be described in terms of variables (non-equilibrium state variables) that represent an extrapolation of the variables used to specify the system in thermodynamic equilibrium.
Explanation:
Answer : First, he should measure how long it takes for the liquid to become clear if X and Y are mixed together. Then, he should measure how long it takes if he also adds substance A to X and Y. He will find out if substance A is a catalyst
Explanation : Measuring the time taken for the liquid to become clear when X and Y were mixed together will give an assumption about the reaction time and the rate of reaction.
Then same measurement should be done when the substance A is added to the liquid of X and Y mixture. If there is a fast reaction that occurs when A is added to the reaction mixture then it can be concluded that A acts as an catalyst for mixing X with Y. Also, by comparing the reaction rates of both the reaction it can be easily concluded that A was a catalyst or not.
The magnetic forces exerted by the magnet can act at a distance on other magnets or on objects containing certain metals. The magnetic fields showcase the presence of magnetic forces. The magnetic forces arise due to attraction and repulsion of the poles inside the material. Opposite poles attract each other while similar poles repel each other.
