Answer:
Limitations of Rutherford Atomic Model
Although the Rutherford atomic model was based on experimental observations it failed to explain certain things. Rutherford proposed that the electrons revolve around the nucleus in fixed paths called orbits. ... Ultimately the electrons would collapse in the nucleus.
The answer to this question would be: 3 molar
A molar unit will be equal to moles of solute per 1 liter of solvent. In this question, you are given the volume of the solution (264.8ml) and the weight of the molecule(139mg). Since the unit is moles not mg, then you need to convert the molecule into moles. To do that you need to know the ascorbic acid molecular weight which was: 6*12 + 8*1 + 6 *16 =<span>176mg/moles.
molecule in moles= 139mg/ (176 mg/moles)= 0.79 moles
Then the molarity of the juice should be: 0.79 moles/ (1000ml/264ml)= 2.991 M= 3 M</span>
Your answer would be C. Alpha decay involves the ejection of 2 protons and 2 neutrons from the nucleus for a total of 4 amu lost. This form of decay is most common in heavy elements.
I’m going to assume here that you meant “plants”.
Animals rely on plants as a source of food. Herbivores way plants to survive and carnivores eat the herbivores to live.
Now plants rely on animals because their scat fertilizes the plants, helping them grow and survive longer.
