electron configuration is the long list underneath the name "calcium" on the element. it starts with 1s^2s^2
Answer:
0.404 moles Na⁺ and 0.404 moles Cl⁻
Explanation:
In the solution you have 23.6g of NaCl. As molar mass of NaCl is 58.44g/mol. Moles you have present are:
23.6g NaCl × (1mol / 58.44g) = <em>0.404 moles of NaCl</em>
As you can see in the formula, each mole of NaCl contains 1 mole of Na⁺ and 1 mole of Cl⁻. Thus, moles of each ion are:
<em>0.404 moles Na⁺ and 0.404 moles Cl⁻</em>
higher temp means higher speed. the will be more energy in the molecules to move, therefore, higher speed
