No math is needed to explain this. All that you need to know is that the can (4°C) is in your hand (37°C).
Entropy will always move toward being balanced. Never will you find a lake in which half of it is 1°C and the other half is 70°C; it will be equal throughout.
Remember that "cold" doesn't exist. What we describe to be cold is actually a lack of heat.
So, by applying the two ideas above, it can be concluded that:
Since your hand is warmer than the can, the heat from your hand will be transferred to the can in order to reach an equal temperature.
The Halogen that is most likely easy to be oxidised would be the Iodine. In addition, the property that makes the Iodine ideal for oxidation is due to the fact that its d-orbital contains more electrons compared to other halogens such as fluorine where oxidation would tend to be difficult to occur on the element.
Answer:
Br2+ 2H2O + SO2= 2HBr + H2SO4
Let's Compare the left side of the equation to the right side of the equation.
Left: Br= 2, H= 2, S= 1, O = 1+2
Right: Br=1, H= 1+2, S=1, O= 4
We can see that only S is balanced and not the other 3 elements.
I'll try to make each element balance.
For Br; I'll multiply by 2 on the left to make it equal to the right.
For H; Since the 2 for Br on the right affected also H, that H ( for HBr) Already has a 2, but then it adds with the other H2( for H2SO4) to give a total of 4 H on the right side. But then there's only 2 H on the left. so we multiply that 2 by a 2 ( which is written infront of the H2O to give a total of 4 H on the left side.
For O; Because of the 2 infront of the H2O, it affects the O in H2O..so now we have 2 O plus the 2 O ( in SO2) to give a total of 4 O which is equal to the right side.
Answer:
121 million joules energy is released
Explain :
As there are 500 moles of hydrogen gas in a kilogram, this means that burning a kilogram of hydrogen gas releases 500 times as much energy or 121 million joules .
Answer:
Explanation:
Hello,
In this case, the undergoing chemical reaction is:
In such a way, as 7.38 moles of potassium chloride are decomposed, the resulting grams of oxygen are computed considering a 2 to 3 molar relationship in the chemical reaction:
Best regards.
