Answer:
NaOH
Explanation:
Sodium Hydroxide (Caustic Soda) is a base. It shares many characteristics of bleach: Albeit more powerful.
Answer:
In the solid phase, the forces of attraction have completely overcome molecular motion, and the movement of the particles has been reduced to vibrating in place. The particles cannot move past one another and are held in a tightly-packed pattern, so there is very little space between the particles.
The only answer you can be given is a gas. It's size is entirely dependent on the container it is in. No matter what the container, a liquid has a definite side. A solid is definitely not the answer.
Answer: A Gas.
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.
