<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:
e. H₂O
Explanation:
The specific heat capacity is defined as the amount of heat required to raise the temperature of the substance in 1 unit. If you have to warm your room, you have to choose the substance with the <u>highest</u> specific heat capacity value. This substance will retain the highest amount of heat. From the options, the highest value is 4.184 J/g°C (water, H₂O). Thus, 1 gram of water will retain 4.184 J when the temperature is raised to 1°C. That is a higher amount of heat in comparison with, for example, granite, which is able to retain 0.79 J per gram when the temperature is raised to 1°C.
However, you have to consider that the boiling point of water is 100°C, so the temperature at which you have to warm the room is the temperature at which water will be passing to the gas state.
I just took the test for you the answer is A molecular formula gives only the number and kind of atoms present in a molecule. THIS IS COPYED STRAIGHT FROM THE TEST. have a good day :)
