Answer is: mass of water is 432 grams.
Chemical reaction: 2H₂ + O₂ → 2H₂O.
m(O₂) = 384 g.
M(O₂) = 2 · 16 g/mol = 32 g/mol, molar mass.
n(O₂) = m(O₂) ÷ M(O₂).
n(O₂) = 384 g ÷ 32 g/mol.
n(O₂) = 12 mol, amount of substance.
From chemical reaction: n(O₂) : n(H₂O) = 1 : 2.
n(H₂O) = 12 mol · 2 = 24 mol.
m(H₂O) = n(H₂O) · M(H₂O).
m(H₂O) = 24 mol · 18 g/mol.
m(H₂O) = 432 g.
The answer would be B) Dunes. I hope you have a wonderful day :)
Answer:
1.- Chemical change
2.- Because the atoms in the image are tranformed into a new molecule
3.- Yes, it does
4.- Due to the amount of atoms are the same both in products and reagents
Explanation:
Density = mass/volume
We are given a mass (which I am assuming is in kilograms) and a volume. Divide to find density.
Density of Saturn = 5.69x10²⁶ kg / 8.01x10²³ m³
Density of Saturn = 710. kg/m³
The density of water is 1000 kg/m³, which is higher than the density of Saturn. Since Saturn has a lower density than water, theoretically, Saturn would float in a gigantic bathtub filled with water.
