Acid spills are often neutralized with sodium carbonate. For example
1 answer:
Answer:
4770 grams of sodium carbonate
Explanation:
The reaction that takes place between sodium carbonate and sulfuric acid is:
- Na₂CO₃ (s) + H₂SO₄ (aq) → Na₂SO₄ (aq) + CO₂(g) + H₂O (l)
First we <u>calculate how many H₂SO₄ moles reacted</u>, using the <em>given concentration and volume of solution</em>:
moles = Molarity * Liters
- moles = 18.0 M * 2.50 L = 45 mol H₂SO₄
Then we <u>convert H₂SO₄ moles into NaCO₂ moles</u>, using the <em>stoichiometric coefficients</em>:
- 45 mol H₂SO₄ *
= 45 mol NaCO₂
Finally we <u>convert 45 NaCO₂ moles into grams</u>, using its <em>molar mass</em>:
- 45 mol NaCO₂ * 106 g/mol = 4770 g

Answer:
The table tennis balls represent neutrons that are released when the nucleus splits and cause other nuclei to split
Explanation:
Nuclear fission is defined as the separation of a nucleus into two smaller nuclei.
It takes a neutron to set off a nuclear fission reaction. When that occurs, neutrons are released and those neutrons in turn are what set off other nuclear fissions. This is defined as a Nuclear Fission Chain Reaction. In the model, the one tennis ball that will be thrown will be modeled as the starting neutron that sets of the initial (first) fission. The mouse traps with tennis balls represent the other nucleuses waiting to be struck by the one tennis ball. Once the initial tennis ball strikes the first mouse trap, that mouse trap will release its tennis ball hitting others and continuing the cycle.
It can also be modeled as such:
