Answer:

Hope dat helps

Explanation:

All the data related to the potential energy diagram is shown in the attached image.

Reactants, intermediate, products, activation energy (Ea), and enthalpy change (ΔH).

Enthalpy change (ΔH) is the difference in energy between reactants and products.

ΔH = E of products - E of reactants.

Enthalpy of the reaction is defined as the difference in the potential energy of the products and the reactants. It is represented as

From the image, the points marked represents:

Point A represents the potential energy of the reactants.

Point B represents the intermediate state or transition state in a reaction.

Point C represents the potential energy of the products.

Arrow D represents the activation energy of the reaction.

Arrow E represents the enthalpy of the reaction.

Hence, arrow E represents the enthalpy of the reaction.

Hope this helps! Na+ lost an electron, so I just left a "+" symbol to show that, and fluorine gained an electron, hence the "-" symbol.

What's the difference between series and parallel circuit in table form?​
schepotkina [342]
Hey :)

In a parallel circuit, a different amount of current flows through each parallel branch of the circuit.

In the series circuit, different voltage exists across each component in the circuit.

Whereas in the parallel circuit, the same voltage exists across the multiple components in the circuit.


Hope this helps :)

PLEASE HELP! How many grams of iron metal do you expect to be produced when 245 grams of an 80.5 percent by mass iron (II) nitra
cricket20 [7]
The mass of Fe(NO3)2 you have is 245 g * 0.805 = 197.23 g 

<span>The molar mass of Fe(NO3)2 is 179.85 g/mole so you have 1.0966 moles </span>

<span>From the balanced equation, that is the number of moles of Fe you make since both Fe(NO3)2 and Fe have a 3 in front of them. </span>

<span>The mass of Fe is 1.0966 moles * 55.85 g/mole (atomic mass of iron) = 61.246 g. From the information you are given, your answer should be in 3 sig figs so 61.2 g </span>

<span>Moles of HCl = 8.2 L * 3.5 mole/L = 28.7 moles </span>

<span>From the balanced equation, you need 1/2 the moles of zinc as you have of HCl so you need 14.35 moles. </span>

<span>To get the mass of zinc, multiply moles of zinc by its atomic mass = 938.2 g. From the information given, your answer should be in 2 sig figs so I would report it as 9.4 * 10^2 g, that clearly shows 2 sig figs.</span>
