Multiple Choice

Which gases were the most abundant in the solar nebula?

Explanation:
The main idea is that the solar nebula inherited the universe’s primordial mix, so its gas was dominated by the lightest and most abundant elements: hydrogen and helium. After the Big Bang, most matter was in these two gases, with hydrogen making up roughly three quarters of the mass and helium about a quarter. The heavier elements you’d find as oxygen, nitrogen, neon, argon, carbon dioxide, or methane exist, but only in much smaller amounts compared to H and He, and they often appear in molecules or condensed solids rather than as the bulk gas. So, hydrogen and helium are the most abundant gases in the solar nebula, which is why they are the correct answer. The other gases listed occur but far less abundantly.

    Decent resource, but I wish some explanations went deeper on a few topics. The questions are helpful for speed, but I occasionally hit the same traps. Still, it’s good for quick decision-making and boosting confidence. A few enhancements would make it perfect.

    Still using it in early review sessions. I like that there are no fixed sections; I can drill topics in any order, which fits how I study. The flash cards are surprisingly useful for retention, and the searchable explanations save time during review. Exam readiness feels very achievable.
