Yes, the chemical reaction occurs because new substance is formed and heat energy is released.

<h3>What is chemical reaction?</h3>

Chemical reaction is a process in which one or more substances i.e. the reactants, are converted to one or more different substances i.e. the products so we can conclude that the chemical reaction occurs because new substance is formed and heat energy is released.

sing any data you can find in the ALEKS Data resource, calculate the equilibrium constant K at 25.0°C for the following reaction
prisoha [69]

Answer:

2.76 × 10⁻¹¹  

Explanation:

I don’t have access to the ALEKS Data resource, so I used a different source. The number may be different from yours.

1. Calculate the free energy of formation of CCl₄

                         C(s)+ 2Cl₂(g)→ CCl₄(g)

ΔG°/ mol·L⁻¹:       0         0         -65.3

ΔᵣG° = ΔG°f(products) - ΔG°f(reactants) = -65.3 kJ·mol⁻¹

2. Calculate K

\text{The relationship between $\Delta G^{\circ}$ and K  is}\\\Delta G^{\circ} = -RT \ln K

T = (25.0 + 273.15) K = 298.15 K

\begin{array}{rcl}-65 300 & = & -8.314 \times 298.15 \ln K \\65300& = & 2479 \ln K\\26.34 & = & \ln K\\K& = & e^{26.34}\\&= & \mathbf{2.76 \times 10}^{\mathbf{11}}\\\end{array}

Which of the following is NOT a unit energy? (select all that applies)
docker41 [41]

Answer:

Calories and joules are both units of energy.

Kelvin, Celsius, and Temperature are measures of temperature not technically units of energy.

Since temperature measures the energy of atoms, a true temperature scale must be a positive scale since atoms cannot have a negative energy. Of the three kelvin is technically the only true measure of energy.
