What is the best explanation for the changes in population and steel consumption during the last 50 years on the graph? (1 point)

Past construction of things like hydroelectric dams has continued to meet needs without requiring more construction.

Even though the population has decreased, people are using more and more steel each year.

People have grown to understand the effects of consuming too many resources and have used less steel in their daily lives.

We are running out of the materials needed to make steel, so there will be less and less used each year.

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.

98 ! and brainliest plz ! the below reaction can be categorized as more than one type of reaction. which reactions are these, and what are the types of reactions?

The name of the ion, s2-, is: sulfurous ion sulfide ion sulfur ion sulfate ion
