A because it gives the example of calcium nitrate
Answer:
Explanation:
From the statement of the problem,
B₂S₃
+ H₂O
→ H₃BO₃
+ H₂S![_{g}](https://tex.z-dn.net/?f=_%7Bg%7D)
B₂S₃ + H₂O → H₃BO₃ + H₂S
We that the above expression does not conform with the law of conservation of mass:
To obey the law, we need to derive a balanced reaction equation:
Let us use the mathematical method to obtain a balanced equation.
let the balanced equation be:
aB₂S₃ + bH₂O → cH₃BO₃ + dH₂S
where a, b, c and d will make the equation balanced.
Conservating B: 2a = c
S: 3a = d
H: 2b = 3c + 2d
O: b = 3c
if a = 1,
c = 2,
b = 6,
2d = 2(6) - 3(2) = 6, d = 3
Now we can input this into our equation:
B₂S₃ + 6H₂O → 2H₃BO₃ + 3H₂S
B₂S₃
+ 6H₂O
→ 2H₃BO₃
+ 3H₂S![_{g}](https://tex.z-dn.net/?f=_%7Bg%7D)
I think the correct answer from the choices listed above is option 3. It is the compound Silver bromide that is insoluble to water. It has a very low solubility which is approximately 0.14 milligram per liter of water. Hope this answers the question. Have a nice day.
Answer:
1. Nucleic acids
2. Proteins carbohydrates
3. Lipids
All of which are essential to the cell’s functions. Each is an Important component of the cell and performs a wide array of functions. Combine, these molecules and it will make up the majority of the cell’s mass.
OR ELSE UR A DEAD RAT HEHE :P
Boron would have the lower first ionization energy.
Be: 1s2 2s2
B: 1s2 2s2 2p1 -> electron from the p orbital is easier to eject than than electron from the s orbital.
