Answer:

6.92; neutral

Explanation:

Kw = [H^+][OH^-] = 1.47 × 10^-14

pKw = pH + pOH = 13.83

At neutrality, [H^+] = [OH^-] and pH = pOH

2pH = 13.83

 pH =  6.92

The pH will be 6.92.

At 303 K, this will be the neutral pH, because [H^+] = [OH^-]

What mass of sulfur has to burn to produce 4.5l so2 at 300°c and 101kpa s(s) o2(<br> g. so2(<br> g.?
Mandarinka [93]
S + O2 --> So2. P = 101kPa = 1atm. R = 0.082 atm - L - (mol-K)^-1. Applying ideal gas equation PV = nRT. n = 1x4.5/0.082x573 = 0.096mole. According to stoichiometry, moles of S = moles of SO2 = 0.096mol. Mass of S = moles of So2 x molar Wt = 0.095x32 = 3.04moles. Hope it helps
