The correct answer is: -3 (minus three)
Explanation:
To find the overall charge, we add electrons and protons. Make sure that you use the negative sign for an electron and positive sign for proton.
There are 10 electrons. It means the charge is "-10"
There are 7 protons. It means the charge is "+7"
Add both of them:
+7 - 10 = -3
Therefore the overall charge on this ion is -3.
Answer: 500L
Explanation:
No of moles= volume× molarity/1000
No of moles =0.5moles
Volume=?
Molarity of a gas at stp = 1M
Stp means standard temperature and pressure
No of moles = volume ×molarity/1000
Substitute the values
0.5=volume×1/1000
Cross multiply
Volume = 1000×0.5
Volume = 500L
The volume is 500L
Well, which one of the choices is different? Freezing, solidifying, and condensing mean that the substance is getting colder. With melting, heat is being added to the substance meaning it is changing to a less condensed state of matter. The answer is melting.
Since there is an equal number of each element in the reactants and products of 3H2SO4 + 2B(OH)3 = B2(SO4)3 + 6H2O, the equation is balanced.
<h3>What is
Sulfuric acid?</h3>
- Sulfuric acid (H2S04) is a corrosive substance, that destroys the skin, eyes, teeth, and lungs. Severe vulnerability can result in death. Workers may be harmed from disclosure to sulfuric acid. The level of exposure depends on
- The sulfuric acid bleaching can substitute the presently assumed oxygen and chlorine stages if the additives are allowed. This bleaching process was also practical for oxygen-bleached hardwood kraft pulp, but it was less compelling for softwood kraft pulp and oxygen-bleached softwood kraft pulp.
- Disbanding sulfuric acid in water is an exothermic procedure. When sulfuric acid is mixed with ice this exothermic procedure causes the temperature to rise at first, but as more of the ice dissolves, the temperature falls.
