Answer:
two north poles and two south poles
Explanation:
A single magnet has a north pole and a south pole. If it is broken into two pieces, then each of the two pieces will have a north pole and a south pole.
No matter how many times or into how many pieces a magnet is broken, the resulting pieces will have two poles each.
The question is asking to state the conclusion that can be formulated, base on the problem or the given analysis of the data, about the accuracy and precision and base on my research, i would say that the Accuracy is Poor but the Precision is Good. I hope this would help you
Answer: B. Hydrolysis (adding water)
Explanation:
When peptide bonds join two or more amino acids together, this is refered to as a peptide. A polypeptide simply means several amino acids. We should also note that proteins contains polypeptides.
The reaction that is capable of breaking polypeptides into their component amino acids is hydrolysis. This simply means a chemical process whereby a water molecule is being added to a particular substance.
C.) Surface Tension, Because water can hold a certain amount of pressure/weight before the object sinks
The molar mass of the compound is 68 g/mol.
<h3>What is the molar mass?</h3>
The Osmotic pressure can be obtained from the relationship;
π= iCRT
π= osmotic pressure = 28.1 mmHg or 0.037 atm
i = Vant Hoff factor = 1
C = concentration = ?
R = gas constant = 0.082 atmLK-1Mol
T = temperature = 20°c + 273 = 293 K
C = π/iRT
C = 0.037/1 * 0.082 * 293
C = 0.0015 M
Now;
Number of moles = C/V = 0.0015/100 * 10^-3
= 0.015 moles
Number of moles = mass/molar mass
Molar mass = mass/Number of moles = 0. 102 g/ 0.015 moles = 68 g/mol
