CH4 + 02 → H20 + CO2
balance equation
CH4 + 2O2 → 2H2O + CO2
4 ÷ ( 12 + 4 ) = 0.25 mol
1 : 2
no mole of H2O = 0.25 × 2 = 0.5 mol
mass of H2O = 0.5 × ( 2 + 16 ) = 9g
Answer:
From the statements mentioned about Convergent Boudaries we can select the following as true.
- Convergent boundaries are where two plates move toward each other. By definition this statement is true.
- New oceanic plate (oceanic lithosphere) is created at convergent boundaries. True, a new oceanic plate can form from the action of convergent boundaries at midocean, lava and million of years do the remaining job.
- Convergent boundaries that have subduction occurring provide a "pull" force that contributes to plate motion. False, Subducting melt and ascend trough the rock creating a volcanic eruption cone and producing an island chain.
- Oceanic plates can be destroyed at convergent boundaries due to subduction. False, The older plate will subduct due to its density and it is forced deep into the mantle, it will melt once the deepth is reached.
