NGSS Statement from PS1.A HS :
Item Description
EC003002
During the reaction between methane and oxygen, energy is required to break bonds, and energy is given off as bonds are formed.
EC004005
The reaction between nitrogen and oxygen takes in energy because the total bond energy of the reactants is greater than the total bond energy of the products.
EC005003
The reaction between nitrogen and hydrogen gives off energy because the total bond energy of the reactants is less than the total bond energy of the products.
EC052002
During the reaction between hydrogen and iodine, energy is transferred from the reaction system to the surrounding system. (This item uses an energy transfer model.)
EC053002
The reaction between bromine and hydrogen takes in energy because the total bond energy of the reactants is greater than the total bond energy of the products. (This item uses molecular models and graphs.)
EC054002
The reaction between methane and chlorine takes in energy because the total bond energy of the reactants is greater than the total bond energy of the products. (This item uses graphs.)
EB055001
During photosynthesis, more energy is required to break bonds between molecules of CO2 and H2O than is released as bonds form between molecules of C6H12O6 and O2.
EB022002
The process by which organisms obtain energy from food involves a chemical reaction between oxygen and carbon-containing molecules from food. During the reaction, atoms are rearranged to form different molecules, and energy is released as the bonds of these new molecules form.
EB018002
The energy required to separate atoms of the reactants of photosynthesis is greater than the amount of energy released when products form.
EB025002
The amount of energy required to separate atoms of the reactants of cellular respiration is less than the amount of energy released as atoms connect to form products.
EC007003
The reaction between methanol and oxygen releases energy because the amount of energy released when bonds form is greater than the amount of energy required to break bonds.
