The required moles of AgBr precipitate produced by given moles of silver nitrate is 0.0123.

<h3>How do we calculate moles from molarity?</h3>

Molarity of any solution is define as the moles of solute present in per liter of the solution and it will be represented as:
M = n/V

Given that, molarity of AgNO₃ = 0.250M

Volume of AgNO₃ = 49.5mL = 0.0495L

Moles of AgNO₃ = (0.25)(0.0495) = 0.0123mol

Given chemical reaction is:

2AgNO₃(aq) + CaBr(aq) → 2AgBr(s) + Ca(NO₃)₂(aq)

As it is mention that CaBr is present in excess quantity and AgNO₃ is the limiting reagent so the formation of precipitate will depend on the AgNO₃.

From the stoichiometry of the reaction, it is clear that:

2 moles of AgNO₃ = produces 2 moles of AgBr

0.0123 moles of AgNO₃ = produces 2/2×0.0123=0.0123 moles of AgBr

Hence 0.0123 is the required moles of precipitate.

Igneous intrusion D is younger than layers B, C, and E according to
Maurinko [17]

Answer:

Law of cross-cutting relationships

Explanation:

This interpretation is based on the law of cross - cutting relationships.

This law states that "faults and fractures that cuts through a rock are younger than the rocks they cut through".

  • In a sequence of strata, the strata that are not cut through by these features are younger than the cross -cutting features.
  • The igneous intrusion is younger since it cuts through the rock layers.
