The greater the energy, the larger the frequency and the shorter (smaller) the wavelength. Given the relationship between wavelength and frequency — the higher the frequency, the shorter the wavelength — it follows that short wavelengths are more energetic<span> than long wavelengths.</span>
Lead<span> (/lɛd/) is a chemical </span>element<span> in the carbon </span>group<span> with symbol Pb (from Latin: plumbum) and atomic </span>number<span> 82.

Answer:
0.125 atm
Explanation:
From the question,
Applying boyles law
PV = P'V'................................. Equation 1
Where P = Initial pressure, V = Initial volume, P' = Final pressure, V' = final Volume.
make P' the subject of the equation
P' = PV/V'............................. Equation 2
Given: P = 97.5 atm, V = 90 mL = 0.09 L, V' = 70 L.
Substitute these values into equation 2
P' = 97.5×0.09/70
P' = 0.125 atm
Answer:
-184.6 KJ/mole
Explanation:
H2(g) + Cl2(g) ------------> 2HCl(aq)
Δ H0 rxn = Δ H0f products - Δ H0f reactants
= 2×-92.3 - (0 + 0)
= -184.6KJ/mole
H2(g) + Cl2(g) ------------> 2HCl(aq) Δ H0rxn = -184.6KJ/mole
