Answer:
Pb(NO3)2 + 2NaCl = 2NaNO3 + PbCl2
That new volume will be 0.25 L. You use the formula P1V1 = P2V2.
Answer:
0.2M H2C6H5O7 < 0.2M H2C2O4
Explanation:
A weak acid/base ionizes to a very small extent in water. Hence, if we say that a substance is a weak acid/base, its percentage of ionization in solution is very little.
More volume of a very weak acid is required to neutralize a strong base. Since NaOH is a strong base, the weaker acid among the duo will require more volume for neutralization.
Since H2C6H5O7 is a weaker acid than H2C2O4, equal concentration of the both acids will require less volume of H2C2O4 than H2C6H5O7 to neutralize 0.50 M NaOH.
Answer:
C. Its viscosity decreases with increasing temperature
Explanation:
- The liquid Sulphur is a liquid that turs yellowish green. At a temperature of 120 it tends to melt and has a lower viscosity.
