Water is always on the move. Rain falling today may have been water in a distant ocean days before. And the water you see in a river or stream may have been snow on a high mountaintop. Water is in the atmosphere, on the land, in the ocean, and underground. It moves from place to place through the water cycle.
Where's the water?
There are about 1.4 billion km3 of water (336 million mi3 of water) on Earth. That includes liquid water in the ocean, lakes, and rivers. It includes frozen water in snow, ice, and glaciers, and water that’s underground in soils and rocks. It includes the water that’s in the atmosphere as clouds and vapor.
If you could put all that water together – like a gigantic water drop – it would be 1,500 kilometers (930 miles) across.
Hello!
the correct setup is shown at bottom of your question
we get
total moles*(1/102.0 g/mol)= total grams Al2O3
hope this helps. any questions please ask. thank you kindly
Answer:
Explanation:
1. Write the unbalanced equation
X + N₂ ⟶ X₃N
2. Balance the equation and gather all the data.
MM: 28.01
6X + N₂ ⟶ 2X₃N
m/g 1.486 1.000
3. Calculate the moles of N₂
4. Calculate the moles of X
The molar ratio is 6 mol X: 1 mol N₂
5. Calculate the molar mass of X
6. Identify X.
Moving air has kinetic energy. Anything that has kinetic energy has the ability to do work. Wind turbines change the kinetic energy of the wind into electrical energy. This form of energy production is also free of pollution

Answer:
Uh first of all this is algebra but I'll answer this
First distribute the three and 5 (Multiply them by both terms inside parenthesis.
3x-6=5x+20
Then add like terms
8x=14
Divide 8 by 8 and 8 by 14
x = 14/8
