Write procedural steps that allow you to demonstrate the sun's role in the water cycle using common material - for each explain what you are modeling and how the materials you have chosen represent nature.
Using the accepted value for the volume of 1 gram of water at the temperature of the room that you reported above, what is the accepted value for the density of water
Calculate the preexponential factor, A, for a reaction with a rate constant of 8.72 x 10-2 s-1 at a temperature of 350 K with an activation energy of 44.0 kJ/mol
- Use the Arrhenius Equation: k=Ae−Ea/RT. k is the rate constant, A is the pre-exponential factor, T is temperature and R is gas constant (8.314 J/molK) ...
- Use the equation: ln(k1k2)=−EaR(1T1−1T2) .
- Use the equation ΔG=ΔH−TΔS. .
<h3>What is
exponential factor?</h3>
The Arrhenius equation, an empirical link between temperature and rate coefficient, uses the pre-exponential factor or A factor as the pre-exponential constant. When determined through experiment, it is typically denoted by A, whereas collision frequency is typically left to Z.
Depending on the order of the reaction, the units of the pre-exponential factor A will differ from those of the rate constant. It has units of the first order reaction, s1. It is known as the frequency factor as a result.
The frequency factor, A, is dependent on both how frequently molecules collide when all concentrations are 1 mol/L and whether or not the molecules are appropriately orientated at the time of contact, according to collision theory.

Answer:
<em>Step 1: Write the balanced chemical equation with the states first:</em>
Ca(OH)₂ (aq) + 2NH₄Cl (aq) → CaCl₂ (aq) + 2NH₃ (g) + 2H₂O (l)
<em>Step2: Write the complete ionic equation, break only the aqueous ones only :</em>
Ca²⁺ + 2OH⁻ + 2NH₄⁺ + 2Cl⁻ → Ca⁺² + 2Cl⁻ + 2NH₃ (g) + 2H₂O (l)
<em>Step 3: cancel the spectator ions ( the ions which stay the same like calciumn and chlorine ions here)</em>
<h2> 2OH⁻ + 2NH₄⁺ → 2NH₃ (g) + 2H₂O (l)</h2>
