Which net ionic equation describes this reaction? mg(no3)2(aq) + na 2co3(aq) → mgco3(s) + 2nano 3(aq)
a) 2no3–( aq) + 2na+(aq) → 2nano3(aq)
b) 2no3–(aq) + 2 na+(aq) → 2nano3(aq) + 2no3–(aq) + 2na+(aq)
c) mg2+(aq) + co32–(aq) → mgco3(s)
d) mg2+(aq) + co32–(aq) + 2no3–(aq) + 2na+(aq) → mgco3(s)

Ase your answer to this question on the information below.hydrocarbons and fissionable nuclei are among the sources used for the production of energy in the united states. a chemical reaction produces much less energy than a nuclear reaction per mole of reactant.the balanced chemical equation below represents the reaction of one molecule of a hydrocarbon with two molecules of oxygen.chemical equation: ch4 + 2o2 → co2 + 2h2o + 1.48 × 10−18 jthe nuclear equation below represents one of the many possible reactions for one fissionable nucleus. in this equation, x represents a missing product.nuclear equation: write an isotopic notation for the missing product represented by x in the nuclear equation.

Particles vibrate in a rigid structure and do not move relative to their neighbors.

Choose an equation that represents an enzyme-catalyzed reaction. (a) enzyme + substrate → enzyme-substrate complex (b) enzyme + substrate ←−→ enzyme + products (c) enzyme + substrate ←−→ enzyme-substrate complex → enzyme + products (d) enzyme + substrate ←−→ enzyme-substrate complex → enzyme-substrate complex + products
