The potential energy diagram for a reaction starts at 380 kJ and ends at 100 kJ. What type of reaction does the diagram best rep
ohaa [14]

Answer: A.  Exothermic reaction

Explanation: Enthalpy change for a reaction is sum of enthalpy of formation of products minus sum of enthalpy of formation of reactants.

When the energy level of reactants is above as compared to the products, the reaction is exothermic and when its opposite then reaction is endothermic.

From given information, the potential energy diagram starts at 380 kJ means the energy level of reactants is 380 kJ. It ends at 100 kJ means the energy of products is 100 kJ.

Enthalpy of reaction = 100 kJ - 380 kJ

Enthalpy of reaction = -280 kJ

Negative sign of enthalpy change indicates an Exothermic reaction.

Do the number of moles of a gas impact the pressure of a gas?
lapo4ka [179]
Yes. Avogadro Law gives the relationship between volume and amount when pressure and temperature are held constant. Remember amount is measured in moles. This means the gas pressure inside the container will increase (for an instant), becoming greater than the pressure on the outside of the walls.

You are given a food containing 6 g protein per serving (30g), how much of the food you needto add to 100 ml solution to make a
Bas_tet [7]

Hey there!

500 mg of protein is present in 100 mL of solvent as per the concentration 0.5 mg/mL or 500 g/mL ,

So, 250 mg (0.25 g) of serving food need to be added to 100 mL solvent in order to prepare 50 mg of protein/100 mL solution.

Dilution factor = initial amount of protein / final amount of protein

= 6 g / 0.05 g = 120

Hope this helps!
