Hydrochloric acid is usually purchased in a concentrated form that is 37.0% HCl by mass and has a density of 1.20g/mL. Calculate the molarity of the concd HCl.
1.20 g/mL x 1000 mL x 0.37 x (1/36.5) = about 12 M or so but you do it exactly.
Then mL x M = mL x M
mL x 12 M = 2800 mL x 0.475
Solve for mL of the concd HCl solution.
Au^2S^3+ 3H^2 = 2Au + 3H^2S

Explanation:
"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.
Answer:
The identity does not matter because the variables of Boyle's law do not identify the gas.
Explanation:
The ideal gas law confirms that 22.4 L equals 1 mol.
