Aqueous nitric acid and aqueous ammonia reacts to form ammonium nitrate
HNO₃(aq)+NH₃(aq) = NH₄NO₃(aq)
HNO₃ +NH3 = NH₄ (+) + NO₃ (-)
Therefore the net ionic equation will be;
H⁺(aq) + NH₃ = NH₄⁺ (aq)
Answer:
C) In[reactant] vs. time
Explanation:
For a first order reaction the integrated rate law equation is:
where A(0) = initial concentration of the reactant
A = concentration after time 't'
k = rate constant
Taking ln on both sides gives:
![ln[A] = ln[A]_{0}-kt](https://tex.z-dn.net/?f=ln%5BA%5D%20%3D%20ln%5BA%5D_%7B0%7D-kt)
Therefore a plot of ln[A] vs t should give a straight line with a slope = -k
Hence, ln[reactant] vs time should be plotted for a first order reaction.
Answer:
True!
Explanation:
Soap molecules form something called micelle. If you look it up, these are usually formed if something has a hydrophobic tails (water hating) and hydrophilic heads (water loving).
So essentially when you try to get the grease off of your shirt or hand, the soap hydrophobic ends interact with grease and capture it and the water interacts with the hydrophilic heads to pull the micelle out releasing the grease.

1.429 atm - 1086mmhg
9361 pa-9.36 KPa - 70.21 mmhg
725 mmhg -0.95 atm- 96.26 kpa
calculation
(a) 1 atm = 760 mmhg
1.429 atm = ?
1.429 x760/1 = 1086.34 mm hg
(B) 1 mmhg = 101.325 kpa
? =9361 KPa
9361 x1 /101.25 =70.21 mmhg
760 mm hg= 101.325 KPa
70.21 mm hg=?
70.21 x101.325/760 = 9.36 Kpa
(C ) 1 atm = 760 mmhg
? = 725
= 725 x1/ 760=0.95 atm
1 atm = 101.325 kpa
0.95 =?
0.95 x101.325/1 = 96.26 KPa
Answer:
The correct answer is: K'= 0.033.
Explanation:
The formation of HI from H₂ and I₂ is given by:
H₂ + I₂ → 2 HI K= 29.9
The decomposition of HI is the reverse reaction of the formation of HI:
2 HI → H₂ + I₂ K'
Thus, K' is the equilibrium constant for the reverse reaction of formation of HI. It is calculated as the reciprocal of the equilibrium constant of the forward reaction (K):
K' = 1/K = 1/(29.9)= 0.033
Therefore, the equilibrium constant for the decomposition of HI is K'= 0.033
