Answer:
an increasng atomic number/ increasing proton count
Explanation:
They can distill the muddy water. This can be done by placing it in a can, covered with pipes to collect the boiling water, and then collecting the distillate. The fuel will be used to provide energy for distillation and the solid particles in from the muddy water will remain in the can as residue.
Answer:
[Ar]3d^84s^2
Explanation:
From the question given, we are asked to write the condensed form of electronic configuration of nickel, Ni.
To do this, we simply write the symbol of the noble gas element before Ni in a squared bracket followed by the remaining electrons to make up the atomic number of Ni.
This is illustrated below:
The atomic number of Ni is 28.
The noble gas before Ni is Argon, Ar.
Therefore, the condensed electronic configuration of Ni is written as:
Ni(28) => [Ar]3d^84s^2
It could be both A. and B. but most likely B. because the star can b big but have the same temperature as a smaller star.
