It changes rocks and minerals by water, ice, acids, salt, and changes in the temperature. Once the rock has been broken down a process named erosion happens, it transports bits of rocks and minerals away
Noble gases, the have all 8 valence electrons so they do not have a need to bond
Answer:
0.24 mol/L.
Explanation:
- Ca(OH)₂ dissociates in solution according to the equation:
<em>Ca(OH)₂ → Ca²⁺ + 2OH⁻.</em>
<em></em>
Every 1.0 mol of Ca(OH)₂ dissociates to give 2.0 moles of OH⁻.
∴ The no. of moles of OH⁻ produced from 0.06 mol of Ca(OH)₂ = (2 x 0.06 mol) = 0.12 mol.
<em>∴ [OH⁻] = no. of moles / V of the solution</em> = (0.12 mol)/(0.5 L) = <em>0.24 mol/L.</em>
Answer: Cu
Explanation: It is Cu because the origin of the word Copper comes from the latin word "Cuprum".
