The hydrogen sulfide reacted with oxygen in rainwater moving through the rock.

Jupiter, too, has small amounts of hydrogen sulfide in its atmosphere.

木星的大气层中也有少量的硫化。

The action of oil and natural gas created hydrogen sulfide in the limestone.

But, as they watched the beakers, a bunch of the hydrogen sulfide seemed to be disappearing.

但是，当他们观察烧杯时，一束硫化似乎正在消失。

Second, it's about what scientists say they've detected in the planet's clouds, hydrogen sulfide.

其次，是科学家所说的，他们在地球的云层中发现了硫化。

Like hydrogen sulfide, which smells like rotten eggs.

比如硫化，闻起来像臭鸡蛋。

So, in this case, the hydrogen sulfide could have lost electrons in a redox reaction.

因此，在种情况下，硫化可能在氧化还原反应中失去了电子。

These sediments were anoxic, or poor in oxygen, and they were also full of hydrogen sulfide.

沉积物是缺氧的或含氧量很低的，并且它们充满了硫化。

It warned some communities about high levels of hydrogen sulfide gas escaping from the rotting algae.

它警告一社区注意从腐烂的海藻中释放出的高浓度的硫化气体。

In deep, dark ocean ecosystems, some bacteria use chemicals like hydrogen sulfide as their energy supply instead.

At super high concentrations, it can be toxic like hydrogen sulfide.

在极高浓度下，硫化一样有毒性。

He noted, for example, that hydrogen sulfide would have been much harder to find on planets that are further away.

他指出，例如，在更远的行星上，硫化会更难被发现。

In the aquifer's depths, a layer of clear fresh water sits atop salt water that's saturated with toxic hydrogen sulfide.

在含水层深处，一层清澈的淡水就浮在充满有毒硫化的咸水之上。

Like, in this case, it connects the hydrogen sulfide reducers in anoxic sediment with oxidizers closer to the surface.
