Answer:
carbon = 7 atoms
hydrogen = 8 atoms
nitrogen = 4 atoms
oxygen = 2 atoms
Explanation:
Chemical formula = C₇H₈N₄O₂
Elements present:
carbon
hydrogen
nitrogen
oxygen
Number of atoms of each element.
carbon = 7 atoms
hydrogen = 8 atoms
nitrogen = 4 atoms
oxygen = 2 atoms
Answer:
Explanation:
HA(aq)+H2O(l)⟺H3O+(aq)+A−(aq)(1)
you need to solve for the Ka value. To do that you use
Ka=[H3O+][A−][HA](2)
Another necessary value is the pKa value, and that is obtained through pKa=−logKa
The procedure is very similar for weak bases. The general equation of a weak base is
BOH⟺B++OH−(3)
Solving for the Kbvalue is the same as the Ka value. You use the formula
Kb=[B+][OH−][BOH](4)
The pKb value is found through pKb=−logKb
The Kw value is found withKw=[H3O+][OH−].
Kw=1.0×10−14(5)
Answer:
a measure of concentration equal to the gram equivalent weight per liter of solution.
Explanation:
Gram equivalent weight is the measure of the reactive capacity of a molecule. The solute's role in the reaction determines the solution's normality. Normality is also known as the equivalent concentration of a solution.

Compounds are made of two or more atoms of different elements, such as water (H2O) and methane (CH4). Atoms are not drawn to scale. Molecules of compounds have atoms of two or more different elements.
There are 6 Nitrogen atoms
