Answer:
It is reactive because it has to gain an electron to have a full outermost energy level.
Explanation:
The electron configuration of oxygen is 1s2,2s2 2p4.
Oxygen is in group six in the periodic table so it has six electrons in its valence shell. This means that it needs to gain two electrons to obey the octet rule and have a full outer shell of electrons (eight).
The equation structure for the above mentioned reaction can be written as
![B_{2} S_{3}+6 H_{2} O \rightarrow 2 H_{3} B O_{3}+3 H_{2} S \uparrow](https://tex.z-dn.net/?f=B_%7B2%7D%20S_%7B3%7D%2B6%20H_%7B2%7D%20O%20%5Crightarrow%202%20H_%7B3%7D%20B%20O_%7B3%7D%2B3%20H_%7B2%7D%20S%20%5Cuparrow)
<u>Explanation:</u>
Considering the above reaction, When Boron sulfide, reacts with water more violently to form boric acid and hydrogen sulfide gas.
![B_{2} S_{3}+H_{2} O \rightarrow H_{3} B O_{3}+H_{2} S \uparrow](https://tex.z-dn.net/?f=B_%7B2%7D%20S_%7B3%7D%2BH_%7B2%7D%20O%20%5Crightarrow%20H_%7B3%7D%20B%20O_%7B3%7D%2BH_%7B2%7D%20S%20%5Cuparrow)
In order to balance the equation, we can do as follows.There are 2 B - atoms on both sides of the equation, but only 2 H - atoms, and one O - atom on LHS, so we have to balance it by putting 6 in front of water and 2 in front of Boric acid and 3 in front of hydrogen sulphide gas, so that we have 2 B - atoms, 3 - S atoms, 12 H - atoms on both sides of the equation, and it is balanced. Balanced equation is given as,
![B_{2} S_{3}+6 H_{2} O \rightarrow 2 H_{3} B O_{3}+3 H_{2} S \uparrow](https://tex.z-dn.net/?f=B_%7B2%7D%20S_%7B3%7D%2B6%20H_%7B2%7D%20O%20%5Crightarrow%202%20H_%7B3%7D%20B%20O_%7B3%7D%2B3%20H_%7B2%7D%20S%20%5Cuparrow)
Thus a Balanced equation of the above mentioned reaction is written.
Answer:
Carbon
Explanation:
The non metal in the same group as Pb is carbon or C .
I hope this helps you.
H2SO4 or hydrogen sulfate is an acid and NaOH or sodium hydroxide is a base or an alkali. The reaction between an acid and a base or alkali produces a salt and water. The reaction between these substances is shown below:
H2SO4 (aq) + 2NaOH (aq)------>2H20 (L) + Na2SO4 (aq). The salt produced in this reaction is sodium sulfate.
I believe that it is a chemical change.
