does anyone have it??
1. Molecules must collide at a high enough energy to break bonds.
2. The minimum amount of energy required to break bonds and start a chemical reaction.
3. Adding heat
4. More energy is released when forming the bonds of the products because a lot of heat is given off, which indicates energy was released.
5. Two H-H bonds are broken, one O=O bond is broken, and four H-O bonds are formed.
100% correct
Just took the quick check

thank you
does anyone have reactants vs product quick check?
1)The number of atoms of each element in the reactants is the same as the number of atoms of each element in the products.
2) 2 moles
3) H2SO4
4) 1 mole of lead (II) nitrate and 2 moles of potassium iodide
5) There will be 1 mole of silver (Ag) in the product. Ya welcome
