Answer:
Explanation:
Resonance structure occurs in an organic compound that undergoes resonance effects. This resonance effect is sometimes called the mesomeric effect helps to increases the stability of organic compounds that have alternating single bonds and double bonds.
The second resonance structure diagram for the ion given in the question can be found in the attached diagram below.
Answer:
Conversion of kinetic energy to potential energy (chemo mechanical energy)
In the state of rest, the rubber is a tangled mass of long chained cross-linked polymer that due to their disorderliness are in a state of increased entropy. By pulling on the polymer, the applied kinetic energy stretches the polymer into straight chains, giving them order and reducing their entropy. The stretched rubber then has energy stored in the form of chemo mechanical energy which is a form of potential energy
Conversion of the stored potential energy in the stretched to kinetic energy
By remaining in a stretched condition, the rubber is in a state of high potential energy, when the force holding the rubber in place is removed, due to the laws of thermodynamics, the polymers in the rubber curls back to their state of "random" tangled mass releasing the stored potential energy in the process and doing work such as moving items placed in the rubber's path of motion such as an object that has weight, w then takes up the kinetic energy 1/2×m×v² which can can result in the flight of the object.
Explanation:
Using charles law
v1/t1=v2/t2
v1=49ml
v2=74
t1=7+273=280k
t2=?
49/280=74/t2
0.175=74/t2 cross multiply
0.175t2=74
t2=74/0.175
t2=422k or 149celcius
The solution for this problem would be:
The mass of P4O10 is computed by: 0.800 mol x 284 g/mol = 227g t = 15.0 s ( 1 min / 60 s) = 0.25 min
So solving for the rate will be mass over t = m/t = 227/0.25 = 908 g/min would be the answer for this problem.
This question needs the answer choices.
I found these choices for you:
<span>0.00032hL
320cL
32mL
Then you need to make the conversion of 0.032 liters to hectoliters, centiliters and milimilters to check which is not equivalent.
1) 0.032 liters to hectoliters:
0.032 liter * 1 hectoliter / 100 liter = 0.00032 hecoliter
2) 0.032 liter to centiliters:
0.032 liter * 100 centiliters / 1 liter = 3.2 centiliter
3) 0.032 liter to mililiter:
0.032 liter * 1000 mililiter / liter = 32 mililiter
Then, the answer is 320 cL: 320 cL is not the same as 0.032 liters
