What is the smallest possible number of products in a decomposition reaction?

1 answer:

3 0

The smallest number of products in a decomposition reaction is two because there is 1 reactant that breaks down and when it does break down there must be two products. It is generally more, though.

Suppose you have 1 kg each of iron, glass, and water, and all three samples are at 10°C.

Kipish [7]

To solve this problem it is necessary to apply the concepts related to heat exchange and Entropy.

The temperature and mass remain constant, therefore the entropy values will be the only ones to change.

Of the three elements given their entropy values are given by

$\Delta S_{iron}=0.45J/gmC$

$\Delta S_{glass}=0.8J/gmC$

$\Delta S_{water}= 4.186J/gmC$

Part A) From thermodynamic theory we know that temperature is inversely proportional to entropy

$T = \frac{E}{\Delta S} \rightarrow$ Energy remains constant

$\Delta t \propto \frac{1}{S}$

Therefore the order would be

Lowest Temperature= Water

Medium Temperature= Glass

Highest Temperature=Iron

Part B) In the case of Energy the opposite happens because it is proportional to the entropy, then

$E = T(\Delta S) \rightarrow$ Temperature is constant

$E \propto S$

Lowest Energy = Iron

Medium Energy = Glass

Highest Energy = Water

Signal far enough ahead so other drivers in your vicinity can make adjustments to your change in speed and ___________.

3241004551 [841]

Answer:

DIRECTION

Explanation:

the answer of the blank will be DIRECTION

As the signal is far ahead so driver can make the decision of what he have to do either he can change direction or he can be on his same path.

But for that driver has to change his or her speed.

so, from the statement given the blank will be filled with DIRECTION
