Explanation:
A. to make it mix better
B. using a spatula
C. fractional destilations
The answer to this question is:
D. balanced.
Good Luck!
The answer is B. Boron
The number of electrons and protons are always the same in an atom.
There are 5 electrons which means there are also 5 protons.
The number of Protons determines the atomic number of an element.
Since the element has 5 protons its atomic number is 5, the same atomic number as Boron
Answer:
C.0.28 V
Explanation:
Using the standard cell potential we can find the standard cell potential for a voltaic cell as follows:
The most positive potential is the potential that will be more easily reduced. The other reaction will be the oxidized one. That means for the reactions:
Cu²⁺ + 2e⁻ → Cu E° = 0.52V
Ag⁺ + 1e⁻ → Ag E° = 0.80V
As the Cu will be oxidized:
Cu → Cu²⁺ + 2e⁻
The cell potential is:
E°Cell = E°cathode(reduced) - E°cathode(oxidized)
E°cell = 0.80V - (0.52V)
E°cell = 1.32V
Right answer is:
<h3>C.0.28 V

Explanation:
To completely describe an electron in an atom, four quantum numbers are needed: energy (n), angular momentum (ℓ), magnetic moment (mℓ), and spin (ms).
