Atoms that have the same number of valence electrons in their outer shell have similar chemical properties and are in the same group in the periodic table.
The final gas pressure : 175.53 atm
<h3>Further explanation</h3>
Maybe the complete question is like this :
A ridged steel tank filled with 62.7 l of nitrogen gas at 85.0 atm and 19 °C is heated to 330 °C while the volume remains constant. what is the final gas pressure?
The volume remains constant⇒Gay Lussac's Law
<em>When the volume is not changed, the gas pressure in the tube is proportional to its absolute temperature </em>
P₁=85 atm
T₁=19+273=292 K
T₂=330+273=603 K
Hello!
The percent yield of the combustion of Nitrogen Oxide in the plant is
65,22%The chemical equation for the reaction is:
2NO + O₂ → 2NO₂
To calculate the percent yield we need to calculate the theoretical yield, using the following conversion factor:
Now we use the following equation to calculate the percent yield:
Have a nice day!
Answer:
i already commented it but i want points anyways its 80 because 20x4 = 80. it said one gram equals 4 calories and there is 20 grams so basically 4+4+4+4+4+4+4+4+4+4+4+4+4+4+4+4+4+4+4+4
They are both related to hold the shape or a part of an organism.
