Agas has a volume of 25.6 l at a temperature of 278 k. what will be the new temperature, in c, if
the pressure is kept constant and the volume is decreased to 16.2 l?

The answer is: -97.23° C

Applying the Charles and Gay-Lussac's Law we have that:

Where:

k is the proportionality constant

v is the volume of the gas

t is the temperature of the gas

We also have the following relation:

Since we need to know the new temperature (T2) we can find it using the last equation, so:

We are asked to find the temperature in Celsius degrees, we must convert the result:

Therefore, the temperature is -97.23° C

Have a nice day!

b) mutualism

hope this : )

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
