Answer:
A silicone atom shares an electron pair with each oxygen atom
Explanation:
Because the silicone dioxide molecule has one silicone atom:two oxygen atoms....
Hence...since silicone has four electrons in the outter shell..which are used for bonding...each oxygen atom shares two electrons(an electron pair) with the silicone atom...so as to fill the outter shell of the oxygen atom
Answer: Two electron configurations of elements that would have similar chemical properties are (2) and (4).
Explanation:
(1) 
(2) 
(3) ![[Ar]4s^23d^5](https://tex.z-dn.net/?f=%5BAr%5D4s%5E23d%5E5)
(4) ![[Ar]4s^23d^{10}^4p^5](https://tex.z-dn.net/?f=%5BAr%5D4s%5E23d%5E%7B10%7D%5E4p%5E5)
Valence electrons : These are the electrons present in last principal quantum number of an atom of the element.
Two electron configurations represent elements that would have similar chemical properties are (2) and (4). This is because number of valence electrons present in both of them are same that is seven valence electrons . Also valence electrons of both the elements are present in p-orbital which means that they both belongs to same group in a periodic table. The members of same group in a periodic table have similar chemical properties.
<span>A 18 M solution of an acid that ionizes only slightly in solution would be termed
concentrated and weak. The concentration of the acid is high. The acid which dissociates partially in water is a weak acid.
</span><span>Calculate the [H^+] for the aqueous solution in which [OH^-] is 1 x10^-9. Is this solution acidic, basic or neutral. To determine [H+] use:
1x10^-14 = [OH-][H+]
solve for [H+]
[H+] = 1x10^-14/1x10^-9
= 1x10^-5</span>
