Reaction 3 is different from the rest and it is because a single product is synthesized.
Option 2
<u>Explanation:</u>
The reaction given in 1,2 and 4 are dissociation reaction where a single compound is getting split into two compounds. So all those three reactions are exothermic as they are breaking the bonds leading to release of energy to the surrounding. But the reaction 3 is a formation reaction, where two chemical compounds are forming a single compound.
So in this case, new bonds are formed leading to absorption of energy from the surrounding. So this is an endothermic reaction. Thus, reaction 3 is different from the rest and it is because a single product is synthesized.
It’s the process of detecting a change of a objects position relative to its surroundings
Substance A will sink because it is more dense than water. An object that is more dense than water will sink and an object that is less dense than water will float.
Answer:
2.52atm for sure
Explanation:
We know that:
P1= 2.80atm
T1= 400k
T2= 360k
And we want to find P2= ?
We have an equation: P1/T1 = P2/T2
Multiple both side by T2 to remove it
P2 = 2.52
