Hello!
The concentration of the reactants decreases and the concentration of products increases during the course of a forward chemical reaction.
A chemical reaction is a thermodynamical process in which two or more substances (called reagents) undergo transformation by the breaking and rearrangement of their chemical bonds to form another substance(s), called products. In a forward chemical reaction, the reagents are being consumed, so their concentration will decrease, increasing the concentration of products as they are the result of the reaction.
The study of how concentration changes with time in a chemical reaction is called reaction kinetics.
Have a nice day!
Answer:
Water has strong hydrogen bond dipole-dipole intermolecular forces that give water a high surface tension and a high heat of vaporization and that make it a strong solvent
The answer is (2) 1.0 dm3. In a balanced equation, the ratio of the mole number of the compounds is equal to the coefficients. And the ratio of volume of gas is equal to the mole number under same condition. So the answer is 1.0 mol.
Q=mcΔT
q=(125g)(0.446 J/(g x °C))(78°C - 23.5°C)
q=(125 g)(0.446 J/(g x °C))(54.5°C) (Be sure to cancel all similar units)
q= 3038.375 J
