Answer:water self-ionize to form an equilibrium system that has [h30+]=1.0x10^-7 M
Explanation:
Answer:
It's the 4th one. waves are created by the wind
0.500 grams would be left after 56.0 days.
After 14 days=4.00 g
After 28 days=2.00 g
After 42 days=1.00 g
After 56 days=0.500 g
This is after four half lives.
Answer: Q= - 405,881 J or -405.88 kJ
Explanation: To find the amount of heat released we will use the formula of heat which is Q = mc∆T.
Q= 2,064 g ( 4.184 J/g°C) ( 45°C -92°C)
= 2,064 g ( 4.184 J/g°C) ( -47°C)
= -405,881 J
Or we can convert this into kJ which is equal to -405.88 kJ.
Answer:
last step= [Pb(H2O)4]^2+ (aq) -----> [PbCl(H20)3]^+ (aq) + H2O (l)
Explanation:
Please see attachment for part of the equation.
The balanced chemical equation for the last step is;
last step= [Pb(H2O)4]^2+ (aq) -----> [PbCl(H20)3]^+ (aq) + H2O (l)
