Mechanical weathering breaks rocks into many pieces creating more surface area for chemical weathering
Geologists look for texture, color, and mineral composition. Since they can be found anywhere such as oceans, deserts, and mountains. <span />
Explanation:
-plants that can absorb copper ions are grown on soil with low grade copper ores.
-the plants are burned and the copper compounds are within the Ash.
-copper ions can be leached from the Ash by adding sulphuric acid, this makes a solution of copper sulphate
-the displacement of scrap iron makes pure copper metals.
First, we need to know what's the gravity value in the moon. it is 1.622 m/ s2
to find the force, let's recall this formula----> Force= mass x gravity
force= 83 kg x 1.622= 134.6
A is the closest choice.
It is non-polar molecule.
CF₄ - dipole moment = 0D
