The potential energy diagram is a common way of depicting the reaction profile. The following are true about the diagram;
- The activation energy of the reaction is 35kJ.
- The enthalpy change of this reaction is 25kJ.
- The slope of the diagram is positive.
- The reaction is endothermic.
<h3>What is a potential energy diagram?</h3>
A potential energy diagram is a diagram that shows the conversion of reactants to products. It can tell us whether the reaction is endothermic or exothermic.
1) From the diagram, the activation energy of the reaction = 65 kJ - 30 kJ = 35 kJ
2) The enthalpy change of this reaction = 55kJ - 30 kJ = 25kJ.
3) The slope of the diagram is positive.
4) The reaction is endothermic.

Answer:
The answer is
<h2>877 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
density = 19.3 g/cm³
volume = 44.9 cm³
The mass of the gold bar
mass = 19.3 × 44.9 = 866.57
We have the final answer as
<h3>877 g</h3>

Answer:
Al3+<Mg2+<Na+
Explanation:
this is because of nuclear charge (no. of protons)
atomic radius is inversely proportional to nuclear charge.
