Answer:
Explanation:
The relation between Kp and Kc is given below:
Where,
Kp is the pressure equilibrium constant
Kc is the molar equilibrium constant
R is gas constant
T is the temperature in Kelvins
Δn = (No. of moles of gaseous products)-(No. of moles of gaseous reactants)
For the first equilibrium reaction:
Given: Kp = 0.174
Temperature = 243 °C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T = (243 + 273.15) K = 516.15 K
R = 0.082057 L atm.mol⁻¹K⁻¹
Δn = (2)-(3+1) = -2
Thus, Kp is:
D. An organism stops taking in carbon when it dies.
Answer:
Ch4 + 2O2 ----> CO2 + 2H2O
Explanation:
Ch4 has 4H, 1C
O2 has 2 O2
CO2 has 1 C, 2O
H2O has 1 H, 2O
you need to add 2 to O2 to balance it. Add 2 to H2O to balance the H and O
Answer:
Pb2+ (aq) & 2Br- (aq) --> PbBr2 (s).
Explanation:
Equation of the reaction:
Pb(C2H32O2)2 (aq) + 2 NH4Br (aq) --> 2NH4C2H3O2 (aq) + PbBr2 (s)
Ionic equation:
Pb+2(aq) + 2(C2H3O2)-1 (aq) + 2(NH4+) (aq) + 2Br-1 (aq) --> 2(NH4+) (aq) + 2(C2H3O2-) (aq) + PbBr2 (s)
2(NH4)+1(aq) & 2(C2H3O2)-1 (aq) cancel out from both sides, you are left with the net ionic equation :
Pb2+ (aq) & 2Br- (aq) --> PbBr2 (s).
opinion and belief mean a judgment that someone thinks is true. ... belief is used if the judgment is certain and firm in a person's own mind without regard to the amount or kind of evidence.
