To convince your responsible work hard to put school and chores first so they know you are very driven. I had also just picked some more chores letting my parents know that I care IDK if it helps
The brackets are indicating a(n) __Hydrogen___ bond.
1. Hydrogen
CThe answer is 64%.
(1) Calculate the molar mass of N2O which is the sume of atomic masses of its elements:
Mr(N2O) = 2Ar(N) + Ar(O)
Ar(N) = 14 g
Ar(O) = 16 g
Mr(N2O) = 2 * 14 + 16 = 28 + 16 = 42 g
(2) Calculate mass percentage of nitrogen in N2O.
Total mass is 44 g: 44g is 100%
Mass of nitrogen is 28 g: 28g is x%
44 g : 100% = 28 g : x
x = 28 g * 100% : 44 g
x = 63.64% ≈ 64%
If the heating is done on one small area on the top, there will be convection. If the heating is restricted to a small fraction of the heating area, then within that area the heating will go deeper than anywhere else on the surface. Then unheated area will have a shallower region of high temperature. Then some convection will occur in the deeper layers, causing some motion on top.
This happens quite a bit during welding. Convection is very significant in welding, even when the heating is from the top.
Answer:
The product would have more acidity than Diethyl malonate
Explanation:
For this question, first, we have to start with the structure of the bromination reaction. <u>The bromination would add a "Br" atom</u> in the middle carbon between the ester groups. Therefore, the molecule produced would be <u>diethyl 2-bromomalonate</u> and the formula of this compound fits with the reported by the question:
Now, if we have to analyze the acidity we have to check the <u>most acidic hydrogen</u>. In this case, is the "H" in the middle carbon (red hydrogen). In the Diethyl malonate, we have an <u>inductive effect</u> caused by the carbonyl groups on each side of the middle carbon. In the diethyl 2-bromomalonate, we have this same inductive effect plus the Br atom bonded to the same carbon. Therefore, would be <u>easier to remove the hydrogen</u>. So, diethyl 2-bromomalonate would ba more acidity than Diethyl malonate.
See figure 1
I hope it helps!
