Answer:
0.1472 mol/L is the concentration of the barium hydroxide solution.
Explanation:
Mass of potassium hydrogen phthalate = 2.050 g
Molar mass of potassium hydrogen phthalate =
According to reaction , 2 moles of potassium hydrogen phthalate reacts with 1 mole of barium hydroxide, then 0.01004 moles of potassium hydrogen phthalate will :
of barium hydroxide
Moles of barium hydroxide = 0.005020 mol
Volume of the barium hydroxide solution = 34.10 mL = 0.03410 L
1 mL = 0.001 L
Molarity of the barium hydroxiude silution :
0.1472 mol/L is the concentration of the barium hydroxide solution.
Given by the name of these compounds, they are formed if one or more hydrogen atoms are substituted for halogens
X = Cl, Br, I, F
Answer:
potassium
The third alkali metal is K (potassium). The atomic number of K (potassium) is 19. Thus, the atomic number of third alkali metal is 19
Explanation:
Polarity- a seperation of electric charge leading to a molecule having an electric dipole.
Molecular shape- I<span>dentify the central atom.
Count its valence electrons.
Add one electron for each bonding atom.
Add or subtract electrons for charge
Divide the total of these by 2 to find the total.number of electron pairs.
<span>Use this number to predict the shape.</span></span>
