Answer:
No. Au⁺ has a complete 5d sublevel.
Explanation:
The color of the transition metal/ion arises due to d-d transition which means that when energy of certain frequency is passed though the solution of the transition metal ions, the electrons of the d orbital gain some energy and goes to higher energy level. The energy absorbed lies in the visible region and thus they are appeared colored.
The electronic configuration of Au is:
1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p⁶4d¹⁰5s²5p⁶4f¹⁴5d¹⁰6s¹
If the gold atom looses one electron, then the electronic configuration is:
1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p⁶4d¹⁰5s²5p⁶4f¹⁴5d¹⁰
<u>Hence, in the configuration, the 5d orbital is full filled and there is no scope for d-d transition. </u>
<u>Thus, there will Au⁺ will not be colored.</u>
Answer: Charles' Law
Explanation: At constant pressure, Charles's law states that the volume of a given amount of gas is directly proportional to its temperature on the kelvin scale. [0 Kelvin = 0 Liters gas]
Solution hopes you will get it.If 1 AMU is equal to 1.6605x10^-24, divide 1 gram by the AMU to find how many atoms in 1 gram.
1 / (1.6605x10^-24) = 6.022282445 x 10^23 You can probably round to four decimal places, so you have 6.0222x10^23 atoms of copper in a gram.
Multiply that by 2.15, the number of grams in a penny (6.0222x10^23) x 2.15 = roughly 1.2948 x 10^24 atoms
Answer:
Phase transition is when a substance changes from a solid, liquid, or gas state to a different state. Every element and substance can transition from one phase to another at a specific combination of temperature and pressure.
