<u>Answer:</u> The correct answer is Option c.
<u>Explanation:</u>
Vaporization is defined as the physical process in which liquid particles get converted to gaseous particles.
The value of standard Gibbs free energy is 0 for equilibrium reactions.
To calculate for the reaction, we use the equation:
where,
= standard entropy change of vaporization
= standard enthalpy change of vaporization = 30.7 kJ/mol = 30700 J/mol (Conversion factor: 1 kJ = 1000 J)
T = temperature of the reaction = 353.3 K
Putting values in above equation, we get:
Hence, the correct answer is Option c.
B, C, F, and G are all elements
How did I determine that answer? I looked at a periodic table.
Tin - Sn
Chromium - Cr
Arsenic - As
Nickel - Ni
Bronze is a copper alloy, not an element.
Solder is an alloy made of led or tin (sometimes brass or silver)
Propane is Alkane made up of Carbon and Hydrogen
Answer:
Long term exposure to polluted air results in significant health issues like asthma, lung cancer and Chronic Obstructive Pulmonary Disease (COPD). Breathing air pollution hampers the functioning of lungs among healthy people resulting in respiratory inflammation and heart problems
Endothermic because the separation of the ions dictate the overall reaction
Answer:
nitrogen is used in the production of 1) fertilisers 2) nitric acid 3) nylon 4) dyes and 5) explosives
please give me brainliest if you can :))
