It explodes all over the place
Answer:
269.068 kJ/mol.
Explanation:
<em>ln (k₂/k₁) = (Eₐ/R) [(T₂ - T₁)/(T₁T₂)].</em>
<em>k₁ = 6.20 x 10⁻⁴ min⁻¹, T₁ = 700.0 K.</em>
<u><em>To get k₂:</em></u>
in first order reactions: k = 0.693/(half-life).
∴ k₂ = 0.693/(29.0 min) = 2.39 x 10⁻² min⁻¹, T₂ = 760.0 K.
∵ ln (k₂/k₁) = (Eₐ/R) [(T₂ - T₁)/(T₁T₂)]
∴ ln [(2.39 x 10⁻² min⁻¹)/(6.20 x 10⁻⁴ min⁻¹)] = (Eₐ/(8.314 J/mol.K)) [(760.0 K - 700.0 K) / (760.0 K)(700.0 K)].
3.65 = (Eₐ/(8.314 J/mol.K)) (1.128 x 10⁻⁴).
<em>∴ Eₐ =</em> (3.65)(8.314 J/mol.K) / (1.128 x 10⁻⁴) = <em>269.068 kJ/mol.</em>
Answer:
Gently place 2 fingers of your other hand on the left side of your chest. · Do not use your thumb because it has its own pulse that you may feel. · Count the beats for 30 seconds
Explanation:
Heart rate can be measured using electrocardiography, pulse ... Heart rate is generally expressed as the number of beats per minute (bpm). ... Because perfect accuracy is not always required in pulse-counting,
The balanced chemical reaction is:

We are given the amount of nitric oxide to be used in the reaction. This will be the starting point of the calculations.
27.8 g NO ( 1 mol NO / 30.01 g NO ) ( 4 mol NH3 / 6 mol NO ) ( 17.0337 g NH3 / 1 mol NH3 ) = 10.52 g NH3
