Which of the following describes an exothermic reaction A. ht reactants equals 0 B. ht reactants ht products C. ht equals ht D. ht ht?
Hf, reactants > Hf, products apex
In a balanced chemical reaction the total mass of the products always equals the total what?
In a balanced chemical reaction the total mass of the products always equals the total mass of reactants; this is the law of mass conservation.
What is S in the equation delta G equals delta H minus TdeltaS?
The change in enthalpy between products and reactants in a reaction
When hydrogen and chlorine mix together does the mass change?
No, due to the Law of Conservation of Mass, which states that in a chemical reaction, the mass of the products equals the mass of the reactants.
Why the reaction mixture doesn't have 50 percents reactants and 50 percents products at equilibrium position?
Chemical equilibrium occurs when the rate of the forward reaction is equal to the rate of the reverse reaction. Take this example:2NO2(g) ↔N2O4(g)At this point of the reaction the rate of N2O4 produced from NO2 is the same as the rate of NO2 produced from N2O4. The key aspect to keep in mind is that the amounts (of moles) of products and reactants at equilibrium is not always 50%/50%. It is usually not.Finding the amounts of products and reactants present during a reaction can be found using Q. Q is known as the reaction quotient. Q can be found like so:Q=[products]/[reactants]reaction quotient =concentrations of products (M) / concentrations of reactantsQ is used to find this ratio at a certain point in time during a reaction (not atequlilibrium)Most likely, you will be given Keq, the equilibrium constant, for a reaction. The value tells you the concentrations of products/reactants at equilibrium. Comparing Q and Keqwill tell you whether a reaction is at equilibrium.Not to get off topic, the answer is that equilibrium does not mean that the reaction mixture has 50% reactants and 50% products. Equilibrium means that the rate of the forward reaction equals the rate of the reverse reaction.
Predict the products of the following reaction MgCl2 plus K equals?
Mg + KCl
In a balanced reaction the total mass of the products always equals the?
In a balanced chemical reaction the total mass of the products always equals the total mass of reactants; this is the law of mass conservation.
If keq equals 740 What is favored starting material or product?
Products. keq equals [products] / [reactants] . A (-) Keq indicates a reactant favored reaction.
In the chemical reaction 2AlCl3 equals 2Al plus 3Cl2 the substances Al and Cl2 are called what?
Products
What does it mean if Keq equals 1?
Products and reactions are equally favored in the reactions
How does the mass of the products in a chemical equation compare to the mass of a reaction?
In a closed system, the mass of the products equals the mass of the reactants.
What chemical reaction occur when acids are mixed with bases?
The mass of products equals the mass of reactants.
In an exothermic reaction the difference between the chemical energy of the reactants and the chemical energy of the products equals?
The amount of heat given off by the reaction
The equation G equals H-TS predicts that?
the change in entropy between products and reatants in a reaction
Which of the following describes an exothermic reaction A. ht reactants equals 0 B. ht reactants ht products C. ht equals ht D. ht ht?
Hf, reactants > Hf, products apex
In a balanced chemical reaction the total mass of the products always equals the total what?
In a balanced chemical reaction the total mass of the products always equals the total mass of reactants; this is the law of mass conservation.
If you know the molar masses of the reactants in a chemical reaction can you determine the molar masses of the products?
If you know know the molar masses of the reactants in a chemical reaction you can determine the molar masses of the products because the combined molar masses of the reactants equals the combined molar masses of the products.
