Answer:
33 mL
Explanation:
It is important to recognize that the total amount of pure syrup remains constant:
Total syrup in the stock solution = total syrup in dilute solution
Thus, we can use the dilution formula
V₁c₁ = V₂
c₂
Data:
V₁ = ?; c₁ = 80 %
V₂ = 47 mL; c₂ = 24 %
Calculations:
1. The volume of stock syrup
2. The volume of soda solution
Total volume of dilute solution = 47 mL
The volume of stock syrup = <u>14
</u>
Volume of soda solution = 33 mL
You need 33 mL of soda solution.
A paramedic or an emergency medical technician (EMT) are professionals who transport patients to hospitals and medical facilities, undergo special training in Cardiology, and can earn between $19,900 and $53,000 a year.
Explanation:
A paramedic or an emergency medical technician (EMT) is a licensed healthcare professional who is part of emergency medical services. Paramedic or EMT responds to any emergency calls like 911.
These technicians provide common emergency medical care like move patients to medical facilities, stabilize patients en route, perform basic life-saving resuscitative services, assess the patients and inform hospital, use any restrains if necessary for patient safety, clean any wound, control bleeding etc.
Along with this care, emergency care technicians should be trained in cardiopulmonary resuscitation (CPR).
They should possess CPR training certificate from authorized centers. The paramedics further get trained in pacemaker control to regulate arrhythmias, providing intubation and ventilator support, inserting IV lines and other critical medical services.
Answer:
I do not understand this question. Explain it further in the comment section and I will try my best to help you. :]
Explanation:
The correct answer is B) not asking subjects to agree to participate without first informing them of the nature of the study and possible risks and benefits.
Explanation:
Clinical trials often involve testing treatments such as new vaccines, medicines or therapies. Moreover, these can have different positive or negative effects on participants of the trial. Due to this, one of the basic principles to follow ethical standards for this type of medical research is being completely honest with participants, which includes explaining to them the purpose of the trial, possible risk and also positive benefits.
This is important because in this way participants can make an informed decision on whether to participate or not in the trial which is part of consent. Thus, ethical standards for clinical trials include "not asking subjects to agree to participate without first informing them of the nature of the study and possible risks and benefits".
Explanation:
For this course you should MEMORIZE THREE STANDARD NERNST POTENTIALS: Nernst potential for Na+ = +55mV, Nernst potential for Cl- = -65mV, Nernst potential for K+ = -90mV. (The Nernst potential is the voltage which would balance out the unequal concentration across the membrane for that ion.
