Answer:
The net chemical equation is: 6 H2O(g) + C3H8(g) → 10 H2(g) + 3 CO2(g)
Explanation:
First equation:
The reactants propane and water react to form the products CO and H2
C3H8(g) + 3H2O(g) → 3CO(g) + 7H2(g)
Second equation:
The products CO and H2 will react
CO(g) + H2O(g) → H2(g) + CO2(g)
We should multiply the equation by 3 (to equal the products of the first equation)
3CO(g) + 3H2O(g) → 3H2(g) + 3CO2(g)
Add the second to the first equation:
C3H8(g) + 3 H2O(g) + 3 CO(g) + 3 H2O(g) → 3 H2(g) + 3CO2(g) + 3 CO(g) + 7 H2(g)
The net chemical equation is: 6 H2O(g) + C3H8(g) → 10 H2(g) + 3 CO2(g)
A physical Change, such as a state changing or dissolving, does not create a new substance, but a chemical change does.In a chemical reaction the atoms and molecules that interact with each other are called reactants.In a chemical change reaction the atoms and molecules produced by the reaction are called products.only the atoms present in the reactants can end up in the products. No new atoms are created and no atoms are destroyed. Reactants contact each other, bonds between atoms in the reactants are broken,and atoms rearrange and form new bonds to make new products.
I think c? Hydroelectric power reduces pollution, and A, B are irrelevant.
The purpose is to help you estimate the total distance because a map is zoomed out so they need to scale it down so its small and the scale helps make the distance accurate.
