Answer:

2.5 mole O2 should react (2 * 2.5) = 5.0 mole H2 but there is 6.0 mole H2. H2 remain in excess. O2 is the limiting reactant. mole of H2O formed = 2 * 2.5 = 5.0 mole.

128.3 grams of methane (CH4) is equal to how many moles of methane
Neko [114]
About 8.0 moles of methane.Number of moles = MassMolar mass.

And thus we get the quotient:

128.3⋅g16.04⋅g⋅mol−1=8.0⋅moles of methane.

Note that the expression is dimensionally consistent, we wanted an answer in moles, and the quotients gives, 1mol−1=11mol=mol as required.

How does the creation of oil demonstrate conservation of mass?
Contact [7]

Answer:

In the conservation of mass, mass (which is the same as energy) can never be created or destroyed in the same way oil is formed from the remains of small animals and plants that died and fell to the bottom of the sea and their mass (energy) is conserved as oil.

olga55 [171]
K₃PO₄ → 3K⁺ + PO₄³⁻

PO₄³⁻ + H₂O ⇄ HPO₄²⁻ + OH⁻

HPO₄²⁻ + H₂O ⇄ H₂PO₄⁻ + OH⁻

H₂PO₄⁻ + H₂O ⇄ H₃PO₄ + OH⁻

K⁺, PO₄³⁻, HPO₄²⁻, H₂PO₄⁻, OH⁻

4. Why do compounds form in nature?
frez [133]

so basically a atom type contains the same number of protons. Chemical bonds put elements together to form more complex molecules called compounds. A compound consists of two or more types of elements held together by covalent or ionic bonds. Elements can't be divided into smaller units not using large amounts of energy.
