In chemical reactions mass is doubled
Did you know?
Web4. In a chemical reaction, mass is conserved. This means that a) The mass of the reactants stays the same during a chemical reaction b) The mass of the products stays the same during a chemical reaction c) The type and number of atoms in the reactants equals the type and number of atoms in the products WebThe magnitude of ΔH is dependent upon the amounts of reactants consumed. Doubling the reactants, doubles the amount of enthalpy. 2.Reversing a chemical reaction results in the same magnitude of enthalpy but of the opposite sign. 3.The enthalpy change for a reaction depends upon the state of the reactants and products.

WebAug 27, 2024 · If the concentration of A is doubled, the reaction rate doubles; if the concentration of A is increased by a factor of 10, the reaction rate increases by a factor of 10, and so forth. What are the 4 factors that affect the rate of reaction? surface area of a solid reactant. concentration or pressure of a reactant. temperature. WebWhen the concentration of substance B in the reaction above is doubled, all other factors being held constant, it is found that the rate of the reaction remains unchanged. The most …
WebThe explanation The relationship between pressure and concentration Increasing the pressure of a gas is exactly the same as increasing its concentration. If you have a given mass of gas, the way you increase its pressure is to squeeze it into a smaller volume. If you have the same mass in a smaller volume, then its concentration is higher.
