The answer is prokaryote :)
Given the molarity of the solution is
.
The volume of the solution is 10.9/1000 L
Number of moles of HCl = Molarity * volume of the solution in L
Number of moles of HCl =*
Number of moles of HCl = 2.7 moles.
Therefore number of moles of HCl in 10.9 ml of the stomach acid is 2.7 moles
Answer:
The forensic laboratory system in the United States consists of private and public labs. One well-known public lab is the FBI (the Federal Bureau of Investigation) Public labs are mostly run by police officers and state employees, while private labs are organized as a fee-for-service and they are small with a few large and medium=sized operations.
Explanation:
Idk and it's not even 100 points but I hope this helps.
The law of conservation of energy is one of the most commonly used principles in physics and chemistry wherein it states that "Energy<span> can neither be created nor destroyed; rather, it transforms from one form to another." Therefore, the energy entering the system, should be equal to the amount of energy leaving the system.</span>
Lecithin is an emulsifier agent that's composed of 5 smaller molecules: phosphoric acid, choline, glycerol( is the backbone), and two fatty acids.
The fatty acids, which are hydrophobic (afraid of water), makes this substance more similiar to fats and represent the non-polar part of the lecithin.
The phosphate group is the polar portion of the molecule and it's the negatively charged. The choline is positively charged, which readily dissolve in water<span>.
</span><span>Lecithin is a good emulsifier because of these structural features. the hydrophobic contacts with the oil, while the hydrophilic end contacts with the water.</span>
