Answer: A mass of 124457.96 g ammonia is produced by reacting a 450 L sample of nitrogen gas at a temperature of 450 K and a pressure of 300 atm.
Explanation:
Given: Volume = 450 L
Temperature = 450 K
Pressure = 300 atm
Using ideal gas equation, moles of nitrogen are calculated as follows.
PV = nRT
where,
P = pressure
V = volume
n = no. of moles
R = gas constant = 0.0821 L atm/mol K
T = tempertaure
Substitute values into the above formula as follows.
According to the given equation, 1 mole of nitrogen forms 2 moles of ammonia. So, moles of ammonia formed by 3654.08 moles of nitrogen is as follows.
As moles is the mass of substance divided by its molar mass. So, mass of ammonia (molar mass = 17.03 g/mol) is as follows.
Thus, we can conclude that a mass of 124457.96 g ammonia is produced by reacting a 450 L sample of nitrogen gas at a temperature of 450 K and a pressure of 300 atm.
<h3>The ozone layer acts as a shield for life on Earth. Ozone is good at trapping a type of radiation called ultraviolet radiation, or UV light, which can penetrate organisms' protective layers, like skin, damaging DNA molecules in plants and animals.</h3>

i'd go for universal indicator, bromothymol blue and methyl red
i mean, they have the degrees of acidity (specific color changes)
they have wider ranges of color changes which will lead to the strength of acid
you will know the degree of acidity of the cosmetics
in fact, bromothymol blue is used to detect the slightest level of acid or base in a substance
universal indicator has the pH charts; the range is big so that you can measure the level of acidity effectively
methyl red is sensitive too as the other two mentioned earlier
the other way that's not included in your choices is the pH meter
unlike litmus papers which just have 2 results; either red or blue
phenolphthalein only colorless, pale pink
you won't know the degree of acidity
hope that helps
Carbon fixation is the process of conversion in which carbon-dioxide (inorganic carbon) converts into organic compounds with the help of living organisms and example of this process is photosynthesis.
From the definition, it is confirmed that there is no formation of carbon dioxide takes place i.e. carbon doesn't joined with oxygen molecules.
Thus, carbon fixation is the process in which carbon atoms are added to the molecules of hydrogen and oxygen to make carbohydrates.
