Answer:
Explanation:The buffer is a mixture of ammonia (NH3) and ammonium (NH4+). ... Since ammonia (NH3) is a weak base, it will have a pH above 7 and since ammonium (NH4+) is a weak acid, it will have a pH below 7. Ammonia (NH3) is a weak base and ammonium (NH4+) is a weak acid. Ammonia (NH3) is the conjugate base of ammonium (NH4+).
<h2>Plasma is most likely inflence by - Option C</h2>
This plasma is most likely influenced by magnetic and electric fields. The massive positively charged ions which are influenced the lighter electrons than replace the ions to keep charge impartiality.
Therefore electric field influence the plasma. The movement of charged particles identical to a magnetic field line is not influenced. Plasma contains charged particles which are positive nuclei and negative electrons which can be molded and restricted by magnetic forces.
Alike iron filings in the closeness of a magnet, bits in the plasma will ensue magnetic field lines.
Answer:
1.38 x 
atoms
Explanation:
To get grams to atoms/molecules/particles we need to first convert grams > moles > atoms. This also applies in the other direction, where you have moles as that stepping stone.
Some key information we need:
Magnesium's molar mass= 24g/mol
Avogadro's Number= 6.022 x 
atoms
Where there is 1 mol per 6.022 x atoms
*This maybe be something you want to memorize.
Grams to moles using molar mass , then to atoms using avogadro's number.
55g Mg x 
x 
= 1.38 x atoms
Answer:
B. By removing thermal energy
Answer:
D-block
Explanation:
Transition metals are metals of the d-block elements located between group 2 and 3 in the periodic table. They are called d-block element because the filling of electrons in their electronic configuration ends in the d-orbital.
Now, they have variable oxidation state because of their partially filled 3d orbital i.e the 3d orbital is not completely filled.
