Answer:
Explanation: 1Pa 1 N/m^2. p = F/A and A = F/p = 300N /35 Pa = 8.57 m^2
The first diagram is showing carboxylic acid because carboxyl contains a Carbon atom as the central atom bonded with OH group, a double bonded Oxygen, hydrogen ofc, and a lone R group.
2. It is ester group
3. Correct its ether
4. It's the exact diagram for ethyl alcohol, so correct

Explanation:
Expression for rate of the given reaction is as follows.
Rate = k[HgCl_{2}]x [C_{2}O^{2-}_{4}]y[/tex]
Therefore, the reaction equations by putting the given values will be as follows.
![1.8 \times 10^{-5} = k[0.105]x [0.15]y](https://tex.z-dn.net/?f=1.8%20%5Ctimes%2010%5E%7B-5%7D%20%3D%20k%5B0.105%5Dx%20%5B0.15%5Dy)
............. (1)
![7.2 \times 10^{-5} = k [0.105]x [0.30]y](https://tex.z-dn.net/?f=7.2%20%5Ctimes%2010%5E%7B-5%7D%20%3D%20k%20%5B0.105%5Dx%20%5B0.30%5Dy)
........... (2)
![3.6 \times 10^{-5} = k [0.0525]x [0.30]y](https://tex.z-dn.net/?f=3.6%20%5Ctimes%2010%5E%7B-5%7D%20%3D%20k%20%5B0.0525%5Dx%20%5B0.30%5Dy)
............ (3)
Now, solving equations (1) and (2) we get the value of y = 2. Therefore, by solving equation (2) and (3) we get the value of x = 1.
Therefore, expression for rate of the reaction is as follows.
Rate = ![k[HgCl_{2}]x [C_{2}O^{2-}_{4}]y](https://tex.z-dn.net/?f=k%5BHgCl_%7B2%7D%5Dx%20%5BC_%7B2%7DO%5E%7B2-%7D_%7B4%7D%5Dy)
Rate = ![k [HgCl2]1 [C_{2}O^{-2}_{4}]2](https://tex.z-dn.net/?f=k%20%5BHgCl2%5D1%20%5BC_%7B2%7DO%5E%7B-2%7D_%7B4%7D%5D2)
Hence, total order = 1 + 2 = 3
According to equation (1),
![1.8 \times 10^{-5} = k [0.105]1 [0.15]2](https://tex.z-dn.net/?f=1.8%20%5Ctimes%2010%5E%7B-5%7D%20%3D%20k%20%5B0.105%5D1%20%5B0.15%5D2)
k = 
Thus, we can conclude that rate constant for the given reaction is .
Answer:
+3
Explanation:
-10 + 13 = +3
-10 IS THE NUMBER OF ELECTRONS
13 IS THE NUMBER OF PROTONS
Answer:
8
Explanation:
The atomic mass of an atom refers to the number of protons in the nucleus of an atom. Hence, an element with 6 valence electron mean that it has 6 electrons in its outermost shell.
The atomic Number of elements with 6 valence electrons cannot necessarily be the same, however, elements with 6 valence electrons belong to group six on the periodic table.
From the options given above, :
Atomic number of 8 :
Configuration : 2, 6
Atomic number of 10 :
Configuration : 2, 8
Atomic number of 12 :
Configuration : 2, 8, 2
Hence, only the element with atomic number of 8 has 6 valence electrons in its outer most shell, hence, the answer.
