Based on the information provided, the correct answer to the question is:
1. El CO: (bióxido de carbono) se forma en la combustión de los alcanos, y es uno de los gases que impacta ambientalmente porque origina el "efecto invernadero", el cual a su vez provoca:
- VSP) Calentamiento global
In this context, the carbon dioxide (CO2) formed during the combustion of alkanes is highlighted as a gas that contributes to the environmental impact by causing the "greenhouse effect," leading to:
- Calentamiento global (Global warming)
Therefore, the correct answer corresponds to the letter VSP, which indicates the impact of carbon dioxide on global warming. This association underscores the role of CO2 in the environmental consequences of combustion processes and its contribution to the overall issue of climate change.
