<span>The only scenario that
will allow you to reach an equilibrium mixture involving these chemicals is to
place NH3 into a sealed vessel. This reaction requires pressures between 2100,
3600 psi, and temperatures between 300 and 550 degree Celsius. With this given
temperature and pressure, the ammonia naturally decomposes into nitrogen and
hydrogen gas at the same rate. When this happen, the concentrations of these
chemicals become constant and the system is said to be at equilibrium.</span>
Answer:
C. Yes, if each sample contains 6.02 x 10²³ atoms.
Explanation:
It is possible for each sample to contain 1 mole of each sample if and only if each of the sample if made up of 6.02 x 10²³ atoms.
6.02 x 10²³ atoms is the Avogadro's number. This number is equivalent to a mole of a substance.
- If the amount of matter in the given substance is at least one mole, it is possible that they are made up of one mole each of each substance.
- If they contain lesser amount of atoms, then it is not up to one mole of substance.
- But if it is greater, then, we can have even more than one mole of substance.
A mole is simply a unit of measurement and it is equivalent to 6.02 x 10²³ atoms.
A). 4
.........................
we will calculate pH of nitric acid of 0.1 M concentration. So, concentration of hydrogen ions in HNO3 is 0.1 M. And now by using this formula we will find pOH. So, from this we can say that pH of HNO3 is 1 and pOH of HNO3 is 13.
Answer: reaction type is combustion
Explanation:
C6H14 + 19/2O2 ==> 6CO2 + 7H2O
