Yes, you add water to Campbell's Chicken Noodle Condensed Soup because "condensed" soup is more concentrated and has less water in it. Adding water will dilute the soup mixture to the desired consistency.
Hello!
The balanced chemical equation for the rusting of iron is the following:
4 Fe + 3 O₂ → 2Fe₂O₃
The coefficients to balance the equation are 4,3,2. The fundament of this balance is the Law of Conservation of Mass. This Law states that matter is neither created nor destroyed in a chemical reaction, and in a chemical equation, the moles of each atom is conserved in both sides of the arrow. That means that if 4 Fe atoms are on the left side, 4 Fe atoms should be on the right side.
A suggestion for balancing equations is to start with metal atoms, continuing with non-metals, then hydrogen and lastly oxygen.
Have a nice day!
Enzymes are needed for metabolic pathways in the body, respiration, digestion and other important life processes. When enzymes function properly, homeostasis is maintained. However, if an enzyme is lacking or has an incorrect shape due to genetic mutation, this can lead to disease within an organism.
