Nucleus
Explanation:
they originate in the nucleus
Explanation:
Pressure of a gas is the combined force with which the molecules bombard a unit area of the wall of the container.
1 atm = 760mmHg
= 760torr
= 101325Pa
= 101325Nm⁻²
1mmHg = 1torr
1Pa = 1Nm⁻²
101.325 kPa and 101,325 Pa are the same
1000Pa = 1kPa
101,325 Pa and 1 atm
1atm and 101.325 kPa
Answer:
2NaNO3+1PbO=1Pb(NO3)2+1Na2O
Explanation:
My chem teacher always had us make a T-chart for products and reactants on both sides to help you figure out balancing equations
<span>The slim exit of the
column is first persisted with glass wool or a permeable plate in order to sustain
the column packing element and keep it from getting out of the tube. Then the
adsorbent solid, which is usually a silica, is firmly packed into the glass
tube to make the separating column. The packing of the non-moving phase into
the glass column must be done with precaution to create an even distribution of
material. An even distribution of adsorbent material is very important to lessen
the existence of air bubbles and/or channels inside the column. To finish
preparing the column, the solvent to be used as the mobile phase is delivered
through the dry column. Then the column is said to be "wetted" and
the column must stay wet throughout the entire procedure. Once the column is properly
prepared, the sample to be separated is placed at the top of the wet column.</span>
The answer is the letter “c”
