When electrons are gained the element is negatively charged and when electrons are loss the element is positively charged
The Earth's early atmosphere consisted of Carrbon Dioxide, methane, sulphur, ammonia, nitrogen and smaller amounts (aprox. 0.05%) of other gases.
Answer: 2 PCl3 + 2 Cl2 > 2 PCl5
Explanation: The factors will be 2 moles of PCl3 reacted to 2 moles of chlorine gas Cl2 and the reaction will produce 2 moles of Phosphorous pentachloride PCl5.
For the reactants 2PCl3 +2 Cl2 there will be 2P, Cl (2x3) +
(2x2) so chlorine will have 10. In the product side 2PCl5. 2 P and Cl will have (5x2)=10.
The chemical reaction will have a balance chemical equation.
The answer is false, oxygen
None of them really sound like the answer, but my best guess would probably be the second one. It doesnt give much info.
