Dear friend,
Because the water remains water throughout this process, it is not undergoing any chemical change. There is no new substance or element added but only a change of form.
<h2>Hello!</h2>
The answer is: H2O
<h2>
Why?</h2>
The critical temperature (also known as the critical point) is the temperature above a vapor or gas can't be liquefied no matter how many pressure can be applied. Every substance has a critical temperature which varies according to the substance/compound nature.
For example, the water has a critical temperature of 373.94 °C, it means that above that temperature the vapor and liquid phases can't be distinct and there is no possible way that the vapor became liquid again no matter how many pressure is applied.
The critical temperature of the given elements/compounds are:
H2 : -240 °C
N2: -147 °C
NH3: 132.4 °C
H2O: 373.94 °C
Have a nice day!
Answer:
86.9 g
Explanation:
Use the conversion factor: 4.82 mol H2O x (18.02g H2O/1 mol H2O)
The moles cancel out so we have to multiply 4.82 x 18.02 = 86.9
The answer is 3 sig. figs.
The first one is the answer
