C. Can travel long distances through air
Something that breaks with little force against it.
Answer:
Na: 1s2 2s2 2p6 3s1
Na+: 1s2 2s2 2p6
Na+ electronic configuration resemble that of Neon( 1s2 2s2 2p6)
In general, the electronic configuration of alkali metals ions resemble that of the group zero (noble gas)
The limiting reagent is Copper (Cu).
<u>Explanation:</u>
- To identify the limiting reactant., first balance the reaction.
The balanced equation is:
Cu + 2AgNO3 -----> Cu(NO3)2 + 2Ag
- To find the limiting reactant, take the amount of initial substance and find the number of moles of one of the products. The reactant that gives a product with the least number of moles, is the limiting reactant
= 2.75 mol Cu.
Since there are only 2.50 mol Cu, copper is the limiting reactant, because, with that quantity of copper, only 2.50 mol AgNO3 will be reacted.
