IS THE MASS PRODUCTS OF A CHEMICAL REACTION GREATER THAN OR LESS THAN THE MASS OF THE REACTANTS?
The mass of the products in a chemical reaction is equal to the mass of the reactants, according to the law of conservation of mass. This principle states that matter cannot be created or destroyed in a closed system, so the total mass remains constant throughout the reaction. Therefore, the mass of the products is neither greater nor less than the mass of the reactants; it is the same.

What kind of reaction occurs when the entropy change of an endothermic reaction is negative?
The reaction is exothermic
Can the arrow in chemical equation indicate which compounds have greater mass?
No, the arrow indicates which way the reaction proceeds, often with 2 arrows being used pointing in both directions indicating the reaction is in equilibrium. The compound's mass can be calculated using the molecular mass of the compound from the periodic table.
What if kc expression is greater than 1 in chemistry?
If the Kc expression is greater than 1 in chemistry, it means that the concentration of products in the equilibrium mixture is higher than the concentration of reactants. This suggests that the reaction favors the formation of products at equilibrium.
In a chemical reaction the total mass of the reactants is less than equal to greater than the total mass of the products.?
In a chemical reaction, the total mass of the reactants is equal to the total mass of the products, according to the law of conservation of mass. This principle states that matter cannot be created or destroyed in a closed system, so the mass remains constant throughout the reaction. Therefore, regardless of the changes that occur during the reaction, the total mass before and after remains the same.
How does reaction quotient predicts the direction of a reaction?
The reaction quotient is the ratio of products to reactants not at equilibrium. If the system is at equilibrium then Q becomes Keq the equilibrium constant. Q = products/reactants If Q < Keq then there are more reactants then products so the system must shift toward the products to achieve equilibrium. If Q > Keq then there are more products than reactants and the system must shift toward the reactants to reach equilibrium.
Is the equilibrium constant greater than 1 in the given chemical reaction?
To determine if the equilibrium constant is greater than 1 in a chemical reaction, compare the concentrations of products to reactants at equilibrium. If the concentration of products is greater than reactants, the equilibrium constant is greater than 1.
In chemical equilibrium what happens when Q is greater than K?
When Q is greater than K in a chemical reaction, it means the reaction is not at equilibrium. This indicates that there are higher concentrations of products compared to reactants, so the reaction will shift in the reverse direction to decrease Q and reach equilibrium.
What is relationship between active mass and rate of reaction?
The rate of a chemical reaction increase when the concentration of the reactants increase.
Why amount of reactant and product do not change in reversible reaction?
The amount of reactants and products do not change in reversible reactions because, in a chemical reaction, matter is neither created nor destroyed -- it is only rearranged. This is the law of conservation of matter.
How can one determine if a reaction is favored towards the products or the reactants?
One can determine if a reaction is favored towards the products or the reactants by comparing the equilibrium constant (K) to 1. If K is greater than 1, the reaction is favored towards the products. If K is less than 1, the reaction is favored towards the reactants.
Does an exothermic reaction contain more chemical energy than reactants?
depends , if the reaction is endothermic or exothermic. if the reaction is endothermic , the energy needed to break the bonds is greater than the energy that forms bonds.and to break bonds you need thermal energy , meanwhile forming bonds gives off energy. now if the reaction is exothermic the energy given off the bonds form are greater than the enrgy needed to break them. you know if the reaction is exothermic or endothermic because exothermic have a negitave delta next to d eqn.while endothermic have a positive delta.
Does the size of the reactants affaect the speed of a chemical reaction?
Yes. The more surface area that is exposed, the greater the speed of the 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
What kind of reaction occurs when the entropy change of an endothermic reaction is negative?
The reaction is exothermic
In a chemical reaction the number of atoms of reactants and products must?
I know that this probably isn't the answer that you were looking for but its a start the answer to this question is one of four different answers choose the one that you think is right. A) The same as the number of atoms in the reactants B) Less than the number of atoms in the reactants C) Greater than the number of atoms in the reactants D) The same as the number of molecules in the reactants
What statement describes the potential energy diagram of an exothermic reaction?
The difference in potential energy between the reactants and products.
Can the arrow in chemical equation indicate which compounds have greater mass?
No, the arrow indicates which way the reaction proceeds, often with 2 arrows being used pointing in both directions indicating the reaction is in equilibrium. The compound's mass can be calculated using the molecular mass of the compound from the periodic table.
