find mol of N2 present using gas law equation
PV = nRT
P = pressure = 688/760 = 0.905 atm.
V = 100mL = 0.1L
n = ???
R = 0.082057
T = 565+273 = 838
Substitute:
0.905*0.1 = n*0.082057*838
n = 0.0905 / 68.76
n = 0.00132 mol N2
Molar mass N2 = 28 g/mol
0.00132 mol = 0.00132*28 = 0.037g N2 gas
22.3 is the answer to this question
"Polysaccharide carbohydrate" comprises an S. pneumoniae capsule.
<u>Option:</u> C
<u>Explanation:</u>
The lengthy sequences of carbohydrate molecules, primarily polymeric carbohydrates constructed of units of monosaccharides linked together through glycosidic connections, understood as Polysaccharides. This carbohydrate can respond to water by catalyzing amylase enzymes, which generate component sugars.
A major human pathogen is Streptococcus pneumoniae or pneumococcus. The virulence is primarily due to its polysaccharide envelope, which protects it from the recipient immune response, and this has led to comprehensive study of the shell.
The balanced form of the chemical equation shown is N₂(g) + 3H₂(g) → 2NH3(g) (option A).
<h3>What is a balanced equation?</h3>
A chemical equation is said to be balanced when the number of atoms of each element on both sides of the equation is the same.
According to this question, the chemical equation between nitrogen and hydrogen is given as follows: N₂(g) + H₂(g) → NH3(g)
The balanced form of the chemical equation shown is N₂(g) + 3H₂(g) → 2NH3(g).
