Answer:
2.17 e -14
Explanation:
A strong acid like HCl ionize 100 % in water so [H3O+] = 0.46 M
[OH-] = Kw / [H3O+]
= 1.0 e -14 / 0.46
= 2.17 e -14
Answer:
6, double
Explanation:
Hex- is a prefix for number 6.
Ene- is a suffix for a double bond.
Use the ideal gas law:
PV = nRT
so, T = PV / nR
n=0.5
V= 120 dm^3 = 120 L (1 dm^3 = 1 L)
R = 1/12
P = 15,000 Pa = 0.147 atm (1 pa = 9.86 10^{-6} )
Put the values:
T = PV / nR
T = (0.147) (120) / (0.5) (1/12)
T= 426 K
