The answer would be B
Explanation: There is more Newton force pushing it and since it's on a flat surface it moves more than a higher kg weight block.
As in like, the action or the history?
Answer:
3.38 moles of neon
Explanation:
First you have to multiply the volume (75.8 L) by the density to get the mass. Neon has a density of 0.9002 g/L at STP, we can just assume it's 0.9 g/L.
That leaves the mass at 68.22 g
Then, you divide the mass by the molar mass to get the number of moles. The molar mass of neon is 20.1797 u, we can leave it at 20.18
That leaves you at approximately 3.38 moles of neon
Answer:
Aluminium.
Explanation:
The above electronic configuration can be written in a simplified form as shown below:
1s² 2s²2p⁶ 3s²3p¹
Next, we shall determine the number of electrons in the atom of the element as follow:
Number electron = 2 + 2 + 6 + 2 + 1
Number of electron = 13
Next, we shall determine the number of protons.
Since the element is in its neutral state,
The number of electrons and protons are equal i.e
Proton = Electron
Number of electron = 13
Proton = Electron = 13
Proton = 13
Next, we shall determine the atomic number of the element.
The atomic number of an element is simply the number of protons in the atom of the element i.e
Atomic number = proton number
Proton = 13
Atomic number = 13
Comparing the atomic number of the element with those in the periodic table, the element with the above electronic configuration is aluminium since no two elements have the same atomic number.
Answer:
Your answer is b
Explanation:
the answer is b because if there is no phytoplankton then there will be no fish and if you take out one part of the food chain then the whole chain comes apart. So meaning if there is no phytoplankton, then there is no fish, if there isn't any fish, then the other animals that come to eat at the river will eventually starve to death or move somewhere else to get more food.
