Answer:
Oxides of nitrogen and hydrocarbon
Explanation:
An automobile catalytic converter is a substance that catalyses redox reactions that convert toxic gases emanating from an automobile engine to less toxic gases.
The substance work by converting carbon monoxide (CO) and hydrocarbons to carbon dioxide and water and oxides of nitrogen to nitrogen and oxygen gas respectively.
<em>Hence, in order to check the effectiveness of a catalytic converter, unburned hydrocarbon and oxides of nitrogen are substances to watch out for in the car exhaust. None of these gases should be found in an exhaust with effective catalytic converter and vice versa. </em>
Answer:
1+2=2+1 is the answer for the question
You would have to look for the mass of the sample and the volume of the sample.
Answer:
ΔG° = 41.248 KJ/mol (298 K); the correct answer is a) 41 KJ
Explanation:
Ag+(aq) + 2NH3(aq) ↔ Ag(NH3)2+(aq)
⇒ Kf = 1.7 E7; T =298K
⇒ ΔG° = - RT Ln Kf.....for aqueous solutions
∴ R = 8.314 J/mol.K
⇒ ΔG° = - ( 8.314 J/mol.K ) * ( 278 K ) ln ( 1.7 E7 )
⇒ ΔG° = 41248.41 J/mol * ( KJ / 1000J )
⇒ ΔG° = 41.248 KJ/mol
Answer:
<h2>15 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question
3000 g = 3 kg
We have
net force = 3 × 5 = 15
We have the final answer as
<h3>15 N</h3>
Hope this helps you
