Answer:
480.40 g.
Explanation:
2 SO₂(g) + O₂(g) → 2 SO₃(g),
it is clear that 2.0 moles of SO₂ react with 1.0 mole of oxygen to produce 2.0 moles of SO₃.
∵ 2.0 moles of SO₂ produce → 2.0 moles of SO₃, from the stichiometry.
∴ 6.0 moles of SO₂ produce → 6.0 moles of SO₃.
mass = no. of moles x molar mass of SO₃ = (6.0 moles)(80.066 g/mol) = 480.396 g ≅ 480.40 g.
B:gravel on the bottom of the aquarium
C:temperature of the water
D:amount of oxygen in the water
To solve this we must be knowing each and every concept related to ecosystem. Therefore, the correct option is option A that is algae growing on the glass.
An ecosystem is created by how all living things interact with one another, with the chemical and physical components of their surroundings, and with each other through the movement of energy.
It includes every living item in a certain location along with their nonliving surroundings including air, water, and sunshine. Ecosystems provide for the basic necessities of humans. By supplying us with fresh food and clean water, ecosystems keep us alive.
They supply the basic ingredients we need to meet our demands for food, water, housing, clothes, and transportation. Algae growing on the glass is a biotic factor of an aquarium ecosystem.
Therefore, the correct option is option A.

Answer:
It is a easy answer you are a noob in this question the properties of water help by giving them water you fool
The differing environmental conditions at different altitudes on a mountain lead plants to develop specific adaptations to those conditions. These adaptations can cause variations in characteristics of plant species across altitudes. Such variations may also signal potential speciation events.
Plants found at different elevations on a mountain differ due to adaptions to varying environmental conditions. The primary differences in environmental conditions can be attributed to three main factors - differences in temperature, light and atmospheric pressure across varying altitudes. As one climbs up a mountain, the temperature typically decreases, light intensity may vary, rainfall patterns may change, and atmospheric pressure decreases.
Plants adapt to these variable conditions in several ways. For instance, high altitude plants might develop adaptations to survive colder temperatures, stronger winds, and more intense UV radiation. They might have smaller leaves to reduce water loss, thicker cuticles to handle UV radiation, and can grow closer to ground to escape wind damage. On the other hand, plants at lower altitudes may have broader leaves to capture more sunlight, deeper roots systems to access water resources, and they can afford to invest more resources in growth, as opposed to survival mechanisms.
Observed differences in plant species across altitudes can also suggest potential speciation events, where the separation of populations by altitude leads to the development of new species over time. A possible way to ascertain this would be to observe whether, when grown in the same environment, high-altitude plants respond to low altitude in the same way that low-altitude plants do, and vice versa. This could indicate whether the observable differences are primarily due to environmental factors or genetic variation.
