Answer:
with the molecular formula C3H5(ONO2)3, has a high nitrogen content (18.5 percent) and contains sufficient oxygen atoms to oxidize the carbon and hydrogen atoms while nitrogen is being liberated, so that it is one of the most powerful explosives known.
Explanation:
NTG reduces preload via venous dilation, and achieves modest afterload reduction via arterial dilation. These effects result in decreased myocardial oxygen demand. In addition, NTG induces coronary vasodilation, thereby increasing oxygen delivery.
1) color change - for example, when bleach is shot down by mistake, in colored clothing;
2) gas release - for example, when playing an effervescent tablet in water.
3) heat release - for example in combustion;

Answer:
a) Precision
b) Accuracy
c) Accuracy and precision
d) Accuracy
Explanation:
When an experiment is done more than once to determine if the results are statistically ok, two forms of the validations are possible the accuracy and precision. When the values of the various experiments are close to the known value, then they are accurate. When the values are close to each other they are precise. So, sometimes the results are precise but are not accurate, and vice-versa.
a) Here, the person wants to find if the 5 aliquots will have close results, so, he or she is looking for precision.
b) Here the amount of analyte is already known, and the person wants to identify if the value will be the same when analyzed together with another sample, thus he or she is looking for accuracy.
c) Here the three results will be compared with each other (precision) and with the standard value of the method (accuracy).
d) The methods will be tested, and the values will be compared with the standard known value, so the person is looking for accuracy.
