Answer:
Duck pluck rescue is used to recover individuals who are submerged in the water and within reach.
The rescuer should be made to lie upwards and straight on the rescuer. This will ensure proper flow of blood to the brain and will ensure a higher degree of consciousness and lesser damage to the brain cells in the case when the patient has taken in much water which may have gone to the brain.
7000 chemicals. ..........
Taking away a patient's power to consent and giving it to medical personnel or the government is called medical paternalism.
I believe the answer is A
<span>The usual answer (and correct) is to improve on the insulation, for example by covering the calorimeter, and using two cups, one inside the other.
Further improvements can be made
1) carrying out the experiment over as short a period of time as possible. reason; any calorimeter will loose heat, but the shorter the time allowed, the less heat will be lost.
2) Use a larger calorimeter, with greater volume of solution. reason; the greater the solvent mass requires more energy to obtain the same change in temperature. You get a smaller temp change for the same reaction, so less losses to the surroundings.
3) calibrate your calorimeter heat the same volume of pure water to a similar temperature as that which the reaction produces. Then determine the rate of heat loss over a period of time, say take temp every minute for 30 minutes, and plot a graph. This will give you a calibration curve that you can use to apply a correction for your calorimeter.</span>
