I think th correct answer is D. Change the shape in therefore surface area. Hope this helps :)
An atom is each sphere which are all connected
Answer:
Option D = No, when elements combine to form a new material, they have properties unique to the new materials.
Explanation:
When sodium contact with water it loses its one electron and thus gain positive charge. When there are more sodium atoms present and many atoms do this thus more positive ions are produced and these positive ions repeal each other at high speed and explosion occur.
But when it form compound with other material, it will not showed this behavior.
Example:
Consider the sodium chloride, when it dissolve in water sodium not showed explosion. In sodium chloride sodium already gives its electron to the chlorine and have stable electronic configuration. The sodium present in cationic form. When it dissolve, partial positive charge of water surrounds the Cl⁻ and partial negative charge of water surrounds the Na⁺ ion, ans sodium chloride gets dissolve into water without explosion.
the answer is d hope this helps
First we look at the chemical reaction:
2 Na + Cl₂ → 2 NaCl
Now we should see which is the limiting reagent, so we construct the following reasoning:
if 2 moles of Na reacts with 1 mole of Cl₂
then 2.4 moles of Na reacts with X moles of Cl₂
X = (2.4 × 1) / 2 = 1.2 mole of Cl₂ (way lower that the available quantity of chlorine).
So the limiting reagent is sodium, and from here we can calculate the number of moles of NaCl produced.
if 2 moles of Na produces 2 moles of NaCl
then 2.4 moles of Na produces Y moles of NaCl
Y = (2.4 × 2) / 2 = 2.4 moles fo NaCl (sodium chloride)
