Does anyone have the reactant and product energy change quick check?
1)The number of atoms of each element in the reactants is the same as the number of atoms of each element in the products.
2) 2 moles
3) H2SO4
4) 1 mole of lead (II) nitrate and 2 moles of potassium iodide
5) There will be 1 mole of silver (Ag) in the product. Ya welcome
1. Molecules must collide at a high enough energy to break bonds.
2. The minimum amount of energy required to break bonds and start a chemical reaction.
3. Adding heat
4. More energy is released when forming the bonds of the products because a lot of heat is given off, which indicates energy was released.
5. Two H-H bonds are broken, one O=O bond is broken, and four H-O bonds are formed.
100% correct
Just took the quick check
thank you
does anyone have reactants vs product quick check?
Ty bone is right
does anyone have it??
As an AI, I don't have access to specific quick checks or homework assignments. However, I can guide you on how to determine the reactant and product energy change in a chemical reaction.
To calculate the energy change in a reaction, we need to know the enthalpy values of the reactants and products. Enthalpy (represented as ΔH) is the heat energy absorbed or released during a chemical reaction.
Here's a step-by-step guide to finding the reactant and product energy change:
1. Identify the balanced chemical equation of the reaction you are interested in. For example, let's consider the reaction: A + B → C + D.
2. Look up the standard enthalpy values (ΔH°) of each component involved in the reaction. Standard enthalpy values are typically given in reference tables or can be found through online sources. These values represent the energy change accompanying the reaction under standard conditions.
3. Calculate the energy change for the reactants by adding up the enthalpy values of the reactants. For our example reaction, the reactant energy change would be:
Reactant energy change = ΔH(A) + ΔH(B)
4. Similarly, calculate the energy change for the products by summing up the enthalpy values of the products. For our example reaction, the product energy change would be:
Product energy change = ΔH(C) + ΔH(D)
5. Finally, calculate the overall energy change of the reaction by subtracting the sum of the reactant energy change from the sum of the product energy change:
Overall energy change = Product energy change - Reactant energy change
Keep in mind that these values are specific to the reaction under consideration and can vary depending on the reaction conditions. Additionally, if the reaction is not under standard conditions, you might need to consider additional factors such as temperature, pressure, or concentration.
Remember to consult your textbooks, class notes, or other reliable sources to find the specific enthalpy values for your reaction if they haven't been provided to you.
