Answer:
A) Three pi bonds break; two sigma bonds and one pi bond form.
Explanation:
Diels Alder reaction -
It is one of the chemical reaction , where the reaction of a substituted alkene and a conjugated diene takes place , is referred to as the diel alder reaction .
Where the substituted alkene is referred to as the dienophile .
Hence , it is also known as diene - dienophile reaction.
The mechanism followed by the reaction is same as for pericyclic reaction , in this reaction , there is breakage of three pi bond and the formation of one pi an two sigma bond.
Fire Hazard would be the correct answer
Amonium= NH4+
Sulphate= SO4-2
Together they form: (NH4)2SO4
the molar mass is: <span>132.14 g/mol</span>
Answer:
The answer to your question is: number 2 is correct.
Explanation:
Formula
F = m x a
The formula shows that acceleration and mass and inversely proportional, then if the mass increases 3 times, then the acceleration must diminishes 3 times.
1. The object will accelerate the same amount as before because the mass does not affect the object’s acceleration.
This option is incorrect, the acceleration must diminish.
2. The object will accelerate 1/3 as much because if you apply the same net force but increase the mass, the acceleration will decrease. This option is correct, is what i describe above.
3. The object will not accelerate because now it is too heavy.
this option is wrong, because the object will accelerate.
4. The object will accelerate 3 times as much because if you apply the same net force and increase the mass, the acceleration will increase. This option s incorrect, the acceleration will diminish not increase.
