Answer:
Explanation:
100mL = 0.1L
0.55 M = mol/0.1 L
mol = 0.055 mol
molar mass of KI = 165.998 g
0.055 * 165.998 = 9.13 g of KI
Uranium-235 would be more useful for dating in Cambrian time because Cambrian time was 540 million years ago while the half life of carbon-14 is only 5,730 years
Hope this helps
Answer:
May be the instrument is incorrect or may be error in it.
Explanation:
The copper have not been detected by this test because the test may be not for the detection of copper, may be it is used for identification of another minerals. If there is copper in the lake sample but can't be detected in the test so it means that the instrument which is used for detection is not the right one or having error in that instrument. Every mineral has a specific type of instrument that detect its presence, if we use incorrect instrument for the mineral then we can't detect the presence of that specific mineral.
That's because the solubility
- Temperature is directly proportional to solubility
Higher the solubility higher the temperature
Lower the temperature lower the solubility
So
Less temperature makes enzymes work faster
