At the top of the swing is your answer.
Kinetic energy increases as an object falls. Increase of speed also increases kinetic energy. The kinetic energy is at zero when an object is not moving
Answer:
541.74× 10²³ atoms of C
Explanation:
Given data:
Number of moles of carbon = 89.96 mol
Number of atoms = ?
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ atoms
89.96 mol × 6.022 × 10²³ atoms of C / 1mol
541.74× 10²³ atoms of C
Liquid silver is less dense than solid silver, so the solid silver would sink.
Electrons orbit the nucleus of an atom. They are very small, in fact they are 1/2000 of an amu. Electrons are negative while the inside of an atom includes the positive protons and neutral neutrons. :D
Answer:
![\boxed{ \text{18 mol}}](https://tex.z-dn.net/?f=%5Cboxed%7B%20%5Ctext%7B18%20mol%7D%7D)
Explanation:
(a) Balanced equation
4NH₃ + 3O₂ ⟶ 2N₂ + 6H₂O
(b) Calculation
You want to convert moles of NH₃ to moles of H₂O
The molar ratio is 6 mol H₂O:4 mol NH₃
![\text{Moles of H$_{2}$O} =\text{12 mol NH$_{3}$} \times \dfrac{\text{6 mol H$_{2}$O}}{\text{4 mol NH$_{3}$}} = \textbf{18 mol H$_{2}$O}\\\\\text{The reaction will produce }\boxed{ \textbf{18 mol of H$_{2}$O}}](https://tex.z-dn.net/?f=%5Ctext%7BMoles%20of%20H%24_%7B2%7D%24O%7D%20%3D%5Ctext%7B12%20mol%20NH%24_%7B3%7D%24%7D%20%5Ctimes%20%5Cdfrac%7B%5Ctext%7B6%20mol%20H%24_%7B2%7D%24O%7D%7D%7B%5Ctext%7B4%20mol%20NH%24_%7B3%7D%24%7D%7D%20%3D%20%5Ctextbf%7B18%20mol%20H%24_%7B2%7D%24O%7D%5C%5C%5C%5C%5Ctext%7BThe%20reaction%20will%20produce%20%7D%5Cboxed%7B%20%5Ctextbf%7B18%20mol%20of%20H%24_%7B2%7D%24O%7D%7D)
