Which process results in the formation of sedimentary rocks?
klio [65]

Answer:

A. Rock fragments are layered and pressurized over time.

Explanation:

Sedimentary rocks are derived from pre-existing rocks that have been subjected to agents of denudation, weathered, transported and deposited within a basin.

In the basin, the sediments are accumulated in their final resting position.

  • Sediments are accumulated as layers on top of one another.
  • The pressure of the sediment on top of another forces out water and presses the layers into sheets.
  • Over time, the compression leads to lithification of the rock.
  • During lithification, compaction and cementation occurs.

How much energy is needed to melt 25.4 grams of l2
KATRIN_1 [288]

Answer:

0.7824 KJ

Explanation:

Given data:

Mass of iodine = 25.4 g

Amount of heat required to melt = ?

Solution:

The heat of fusion of iodine is 7.824 Kj /mol

Number of moles of iodine = 25.4 g/ 254 g/mol

Number of moles of iodine = 0.1 mol

The amount of heat required to melt one mole of iodine is 7.824 Kj /mol

For 0.1 mol;

7.824 Kj /mol × 0.1 mol

0.7824 KJ
