Answer:
The lanthanides and actinides together are sometimes called the inner transition elements.
Explanation:
They are called this because they come up in the periodic table after actinium
Hope this helps :)
I'm not exactly sure which one but I do know that an acid and a base react in a aqueous solution to form water, so i would probably eliminate the ones that aren't aqueous solutions.
Answer: They are chemically stable gases
Explanation:
Group 18 is also called the noble gases - because they have full valence shells it means they are stable and won't chemically react.
Answer:
yes it can
Explanation:
because, it depends on where the rock is, for example on a dessert it would Be cracked and things like that if near an eruption it would be the flamey black rock, and so on you get it
Given the Planck's constant and the speed of light, the energy of the ultraviolet light with a frequency of 9.58×10¹⁴ Hz is 6.35×10¯¹⁹ J (Option C)
<h3>Data obtained from the question </h3>
- Planck's constant (h) = 6.626×10¯³⁴ Js
- Speed of light (v) = 3×10⁸ m/s
- Frequency (f) = 9.58×10¹⁴ Hz
- Energy (E) =?
<h3>How to determine the energy </h3>
The energy of the ultraviolet light can be obtained as follow:
E = hf
E = 6.626×10¯³⁴ × 9.58×10¹⁴
E = 6.35×10¯¹⁹ J
