Answer:
Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air).
Explanation:
If really depends on what you're eating, because some foods have added lemon juice on them, like meat, fried rice, and such, while others, like a regular steak, are basic because it literally just has meat on it. But if you really want my opinion, I think that most foods are more likely to be acidic, like coffee, eggs, butter, fruit, cereal, as well as much more daily things that we eat. Although we also eat many basic common foods, acidic foods are much more common in your regular daily meal.

Answer:
Basalt forms when lava cools quickly at the surface. This quick cooling rate results in very small mineral grains. Pumice is formed when volcanoes erupt explosively. It comes from the same kind of magma which would form granite or rhyolite, that is, a magma that contains lots of silica (quartz). Magma with lots of silica is usually thick and sticky
Explanation:
Answer is: volume of methane is 78.4 mL.
n(CH₄) = 0.0035 mol.
At standard pressure and temperature:
V(CH₄) = n(CH₄) · Vm
V(CH₄) = 0.0035 mol · 22.4 L/mol.
V(CH₄) = 0.0784 L · 1000 mL/L = 78.4 mL.
Vm - molar volume.
