marshall27 [118]

Explanation:

<em>The</em><em> </em><em>answer</em><em> </em><em>is</em><em> </em><em>directly</em><em> </em><em>proportional</em><em>, </em><em>because</em><em> </em><em>when</em><em> </em><em>there</em><em> </em><em>is</em><em> </em><em>more</em><em> </em><em>concentration</em><em> </em><em>their</em><em> </em><em>will</em><em> </em><em>more</em><em> </em><em>reactants</em><em> </em><em>to</em><em> </em><em>react</em><em> </em><em>fast</em><em> </em><em>diring</em><em> </em><em>the</em><em> </em><em>chemical</em><em> </em><em>reaction</em><em> </em><em>which</em><em> </em><em>increases</em><em> </em><em>the</em><em> </em><em>rate</em><em> </em><em>of</em><em> </em><em>chemical</em><em> </em><em>reaction</em><em>. </em>

<em>So</em><em>,</em><em> </em><em>we</em><em> </em><em>can</em><em> </em><em>state</em><em> </em><em>that</em><em> </em><em>the</em><em> </em><em>relationship</em><em> </em><em>between</em><em> </em><em>them</em><em> </em><em>are</em><em> </em><em>directly</em><em> </em><em>proportional</em><em>. </em>

Large crystals are formed when _____. igneous rocks cool very quickly metamorphic rocks change into igneous rock sedimentary roc
vivado [14]

igneous rocks cool very slowly

Explanation:

Large crystals are formed when rocks cool very slowly. This gives time for crystallization nuclei to form and other crystals aggregates round it.

  • Large crystals in rocks are typical of intrusive igneous rocks.
  • These rocks are formed beneath the earth surface and they usually have big crystals.
  • This because they cool slowly and have time for crystal formation.
  • Rocks that cools rapidly are extrusive igneous rocks.
  • They are usually fine grained and glassy in nature.
