2C4H10 + 13 02 -- 8 CO2 + 10H20

Anika [276]

Answer:

Option 1. 0.55 mol of C₄H₁₀

Explanation:

The reaction is:

2C₄H₁₀ + 13O₂ → 8 CO₂ + 10H₂O

This is a combustion reaction where carbon dioxide and water are produced.

We convert mass of produced water to moles → 50 g / 18 g/mol = 2.78 moles of water.

The stoichometry states that:

10 moles of water are made by 2 moles of C₄H₁₀

Therefore 2.78 moles of water will be made by (2.78 . 2) / 10 = 0.55 mol of C₄H₁₀

It is possible to make a model of a fission chain reaction with mousetraps and table tennis balls, with the balls placed on an a

konstantin123 [22]

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:
