the correct combo is C
We know sunlight is key factor in photosynthesis so A and D are out.
we also know plants get their bulk by breaking up co2 and using the carbon which releases oxygen as a byproduct so B is also out of the question.
I’m pretty sure the answer is stir the water
Answer:
Spot (4) Has evidence that there were waves here at some point. It looks as if the sand/surface debris was moved back and forth, creating this pattern in the sand. Spots (5) and (7) show evidence of water erosion. The smooth edges of both hills mean that water once flowed through that area, carrying little pebbles and rocks that gradually shaped and smoothed those mounds. An example for this would be how there are smooth areas in the Grand Canyon where scientists have concluded that some, if not all, of the Grand Canyon was formed by flowing water. "Rapid uplift, cracking, and surface drainage of receding floodwaters provide both the path and the necessary volume of water to quickly carve out Grand Canyon," says scholars on icr.org.
Explanation:
Water Erosion exists.
Answer:
0.558mole of SO₃
Explanation:
Given parameters:
Molar mass of SO₃ = 80.0632g/mol
Mass of S = 17.9g
Molar mass of S = 32.065g/mol
Number of moles of O₂ = 0.157mole
Molar mass of O₂ = 31.9988g/mol
Unknown:
Maximum amount of SO₃
Solution
We need to write the proper reaction equation.
2S + 3O₂ → 2SO₃
We should bear in mind that the extent of this reaction relies on the reactant that is in short supply i.e limiting reagent. Here the limiting reagent is the Sulfur, S. The oxygen gas would be in excess since it is readily availbale.
So we simply compare the molar relationship between sulfur and product formed to solve the problem:
First, find the number of moles of Sulfur, S:
Number of moles of S =
Number of moles of S = = 0.558mole
Now to find the maximum amount of SO₃ formed, compare the moles of reactant to the product:
2 mole of Sulfur produced 2 mole of SO₃
Therefore; 0.558mole of sulfur will produce 0.558mole of SO₃
Answer:
The first element is always named first, using entire element name.
Second element is named using its root and adding the suffix -ide.
Prefixes are used to indicate the number of atoms of each element that are present in the compound.
