- In chemical weathering minerals are changed into new minerals and mineral byproducts.
- Some minerals like halite and calcite may dissolve completely.
- Chemical weathering may change the size of pieces of rock materials, but definitely changes the composition.
- So one type of mineral changes into a different mineral.
- Chemical weathering works through chemical reactions that cause changes in the minerals.

Answer: Option (C) is the correct answer.
Explanation:
When the volume of a container is decreased and same number of gas molecules are present inside the container at the same temperature then it means that more number of gas molecules are spread per unit volume.
As earlier when the volume of container was more then the molecules were widely spread inside the container but on decreasing the volume of container, molecules come closer to each other and hence there will be increase in molecules per unit volume.
The molarity of NaBr = 0.05036M
<h3>
calculation</h3><h3>Step1: calculate the total mass</h3>
0.0460 m NaBr has 0.0460 moles NaBr with 1000g of solvent
therefore the mass of NaBr= 0.0460 moles x 102.89 g/mol =4.73grams
total mass is therefore= 4.733 g +1000= 1004.73 grams
step 2:
use the density to determine the volume
vol=mass/density
=1004.73 g/1.10 g/mol=913.39 ml in liters= 913.39/1000=0.91339 L
now the molarity = moles/vol in liters
=0.0460 m/0.91339=0.05036 M
