Answer:
C. CH4 + 202 – CO2 + 2H20
Explanation:
CH4+O2-CO2+H20
The above equation represents combustion of methane to produce carbon-dioxide and water.
One carbon atom is present on the reactant side as well as on the product side. Four hydrogen atoms are present on the reactant side and two hydrogen atoms on product side. In order to balance this equation, we would multiply water molecule by two. Now there are four atoms of oxygen in the product side but only two on reactant side, so we will multiply oxygen molecule by two on the reactant side. Now the equation is balanced.
The balanced chemical equation is:
CH4+202-CO2+2H2O
This equation obeys the law of conservation of mass as the mass of the reactants is same as that of the products.
Frogs eat bugs like crickets. they need them to survive. if there were a decrease in the cricket population it would disrupt the food chain and cause the frog population to decrease because one of their food sources are gone or depletes
Explanation:
Phytoplankton, Zooplankton, Small Fish, Mammal
Phytoplanktons are the small photosynthetic organism that can produce their own feed and so are the producers in this food chain. Zooplanktons are small organisms incapable of producing their own food and eat phytoplanktons. Small fishes consume zooplanktons since due to their small size they are unable to eat bigger organisms. Mammals eat small fishes since they are omnivorer.
