Answer:
1,2, and 3 are correct.
Explanation:
1 is true because cellular respiration begins in the cytoplasm of a cell. 2 is true because cellular respiration releases energy aerobically which uses glucose and oxygen or anaerobically which just uses glucose. Either way, energy is being released. 3 is true, I don't know how to explain why. Just keep the cellular respiration equation in mind, (C6H12O6 + 6O2 → 6CO2 + 6H2O + Chemical Energy (in ATP)), the chemical reactions are basically summed up into an equation. Hope that helped.
To calculate for the number of moles of SnO2 in the sample, we need the value of the products from the reaction. Since we do not have that data, we can assume that all of the sample is SnO2. Then, we are given the molecular mass of the sample, 151g/mol.
So, the number of moles is 3g / 151 g/mol = 0.0199 moles SnO2
Answer:
you can't go through a solid unless you broke the atoms in the wall
<span>The expected results of the Rutherford's gold foil experiment were that the relative massive alpha particles (respect to electrons) could go through the gold foil without being deviated of their trajectory or only small deviations due to the uniformly distributed positive charge of the protons. The real results showed that some particles were significantly deviated of the trajectory (large deviation angles and even some particles bounced back to the source). This lead Rutherford to reject the plum pudding model and propose a new one. The new model proposed by Rutherford was that the atom consisted of a small and every dense nucleus (which contained the positive charge, protons) and a vast region, almost empty, but where the electrons were, surrounding the nucleus.</span><span />
