Answer:
V = 15.2 L
Explanation:
STP means that T = 273 K and P = 1 atm.
We use the<em> PV=nRT equation</em> to <u>convert the given liters of oxygen to moles</u>:
- 1 atm * 7.6 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 273 K
Now we<u> convert O₂ moles to H₂O moles</u>, using the <em>stoichiometric coefficients</em> of the equation:
- 0.340 mol O₂ * = 0.68 mol H₂O
Finally we use the PV=nRT equation once again to<u> convert 0.68 moles of H₂O to liters</u>:
- 1 atm * V = 0.68 * 0.082 atm·L·mol⁻¹·K⁻¹ * 273 K
Conventional volcanoes are known to erupt after pressure builds up from new magma flowing into the magma chambers that lie below the vents on the Earth's surface.
1 mole C6H12O6 -------------- 180.15 g
? moles C6H12O6 ------------ 523.46 g
523.46 x 1 / 180.15 => <span>2.905 moles</span>
Answer: B
Explanation: its natural gas so its repleinishable
Iron Fluoride
A chemical compound is a substance composed of atoms from two or more (different) elements. These compounds are formed by the creation of chemical bonds between the atoms of the different elements.
Helium and Neon are both elements, and in particular, they belong to a group of chemical elements called noble gases. Being noble gases, they are very stable and do not react easily.
Iron fluoride is a chemical compound consisting of the metal, iron, and the nonmetal, fluorine. When a metal and a nonmetal react to form a compound, they form ionic bonds to hold together the atoms of the different elements comprising the compound.
