The equation that conforms with the particle model is 4C + 6O2 ----> 4CO2 + 2O2.
<h3>What is a chemical reaction?</h3>
The term chemical reaction has to do with the combination of substances to give products. We know that reactants and products must follow the law of conservation of mass.
Hence, the equation that conforms with the particle model is 4C + 6O2 ----> 4CO2 + 2O2.

Answer:
1.72x10⁻⁵ g
Explanation:
To solve this problem we use the PV=nRT equation, where:
- R = 0.082 atm·L·mol⁻¹·K⁻¹
- T = 25 °C ⇒ (25+273.16) = 298.16 K
And we <u>solve for n</u>:
- 1 atm * 5.7x10⁶ L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 298.16 K
Finally we <u>convert moles of helium to grams</u>, using its <em>molar mass</em>:
- 4.29x10⁻⁶ mol * 4 g/mol = 1.72x10⁻⁵ g
