Homogeneous materials look the same throughout even throughout even though they contain different materials. --> A. True <--
5 mols = 100 grams
1 mol = 100/5
1 mol = 20 grams.
<u>Given:</u>
Volume of 0.9% NaCl = 500 ml
Time (t) = 4 hrs
<u>To determine:</u>
The infusion rate of NaCl in ml/hr
<u>Explanation:</u>
Based on the information- 500 ml of NaCl is to be given over a time span of 4 hrs
Hence, the volume of NaCl to be administered per hr is:-
= 1 hr * 500 ml/4 hr = 125 ml
Ans: Infusion rate = 125 ml/hr
Answer:
All liquids are fluids but not all fluids are liquids. Fluids basically describe anything that can flow as a result of a difference in pressure between two points. Liquids on the other hand are a subset of fluids. Liquids are the incompressible fluids. These are the fluids who's density does not change sharply with pressure.
Gases are also fluids, they form the compressible fluids. They do flow as a result of difference in pressure between two points but at the same time they can be compressed or expanded. Their density fluctuates with pressure.
Hence fluids consist of 2 mutually exclusive groups of compressible and incompressible fluids. Liquids are the incompressible fluids and hence form a subset of the more general term fluid.
Answer:
The answer is A
Explanation:
Because . . .
- A is correct because scientist make their statements by using their observations and tools to measure.
- B is incorrect people's opinions are not facts! Plus, opinions can be wrong.
- C is incorrect because that book can be outdated and not every answer is in a book.
- D is absolutely incorrect because guessing a "right" answer can be wrong. For example, if you were a scientist and you guessed a treatment for coronavirus, you will defiantly get fired because you don't have evidence or logic to back up your answer. In addition, if people used ur "treatment" the one you have guessed as the "right" answer, you can put people's lives in danger and they can possibly die. You will defiantly be responsible for it and be put into jail.
