<u>Answer:</u> The lewis dot structure is attached below.
<u>Explanation:</u>
A Lewis dot structure is defined as the representation of atoms having electrons around the atom where electrons are represented as dots.
A ketene is an organic compound having general formula R′R″C=C=O, where R and R' are two different/same monovalent chemical groups.
The given chemical compound having formula 
is represented as 
.
Total number of unshared electrons = 4 (left on oxygen atom only)
The lewis dot structure of is given in the image below.
Hello!
Your answer is A.. Earth's core is the most dense layer and it consists of the outer core and the inner core.
Hope this helps :))
Answer:
ability to rust
Explanation:
i'm like 90% sure thats correct
From the reaction between Cu and HNO₃, the formed gas is NO₂ instead of NO₃. Hence the correct balanced equation would be,
Cu(s) + 4HNO₃(aq) → Cu(NO₃)₂(aq) + 2NO₂(g) + 2H₂O<span>(l)
Here, Cu goes to </span>Cu(NO₃)₂ by changing its oxidation number from 0 to +2 while NO₃⁻ goes to NO₂ by reducing its oxidation state from +5 to +4 . Hence Cu is oxidized by HNO₃ in the reaction.
Um let me think ummm dang hold on bro i will be right back ok
