Answer:
The percent yield of reaction is 54.32%.
Explanation:
Moles of methane =
According to reaction, 1 mole of methane gives 2 moles of water .
The 0.3115 moles of methane will give:
of water
Mass of 0.9345 moles of water = 0.623 mol × 18.02 g/mol = 11.23 g.
Theoretical yield of methane = 11.23 g.
Experimental yield of methane = 6.10 g.
The percent yield of reaction:
The percent yield of reaction is :
Answer:54.5
Explanation:
(2) emitted by the electron
(3) absorbed by the nucleus
(4) absorbed by the electron
An atom of oxygen is in an excited state. When an electron in this atom moves from the third shell to the second shell, energy is emitted by the electron. Hence, option B is correct.
The smallest piece of stuff that still retains its characteristics is an atom. A gold atom, for instance, is the smallest piece of that element that will still retain all of gold's properties and behaviors. When an atom is disassembled into its component parts, the subatomic particles found inside each have special characteristics that are not at all similar to those of the element the atom represents. Protons, neutrons, and electrons are the three different subatomic particle kinds.
The electron that transitioned from a higher to a lower level felt the change in energy level. Since the nucleus is unaffected, its energy levels are unaffected as well. Since it requires more energy to keep an electron at a higher energy level than a lower one, the shift in energy levels indicates that the electron released some energy.

Please don't jugde me if I got it wrong
Answer:
I belive its liquid if I'm right because liquids are packed together when they take shape but they are still able to move.....brainliest???
