Mass of lead Pb = 4.00 g (given)
Density of lead= 11.34 g/mL (given)
When lead is placed in a graduated cylinder which is partially filled with water, the volume of lead will be the volume of water displaced by it.
Density (d) of a substance is the ratio of mass (m) to the volume (m) of the substance.
The formula of density is given as:
Putting the given values of density and mass of lead, we get
Rearrange the equation, to find the volume
Therefore, volume replaced by lead is 0.353 mL

Explanation:
Answer:
5.94
Explanation:
At equilibrium
⇒[CH3NH^+] = 0.130/2= 0.065 M
hence we can write that
x= concentration of H+ ions
⇒2×10^(-11)×0.065 = x^2
⇒x= 1.14×10^{-6}
therefore ph=log [H+]= log[ 1.14×10^{-6}]= 5.94
Answer:
Hydrogen bond is formed only by the three highly electronegative elements- fluorine, oxygen and nitrogen.
Binary ionic compounds contain two elements: one metal and one nonmetal. are binary ionic compounds. Ternary ionic compounds contain three elements, at least one metal and one nonmetal.
