Answer:
no
Explanation:
Because gravity is necessary for density differences to arise, convection wouldn't happen in a zero-gravity environment such as space.
Hydrogen peroxide is H2O2, while water is H2O and oxygen (a diatomic gas) is O2. The (unbalanced) reaction is:
H2O2 --> H2O + O2
Notice that the H2O2 has 2 H atoms, and so does H2. This means that both must have the same coefficients, and we can adjust the coefficient of O2. Since H2O2 has 2 O atoms, and H2O has 1, we multiply O2 by 1/2:
H2O2 --> H2O + (1/2)O2
This has an equivalent number of H and O atoms on either side, but we want the coefficients to be whole numbers, so we multiply everything by 2:
2H2O2 --> 2H2O + O2
The best steps that should always be used for effective problem solving would be C. Developing a plan and then implementing the plan.
Answer:
Rusting is an oxidation reaction. The iron reacts with water and oxygen to form hydrated iron (III) oxide, which we see as rust. Here is the word equation for the reaction: iron + water + oxygen → hydrated iron (III) oxide
In this reaction, zinc atoms each will lose two electrons (oxidation) and become Zn 2+ ions. The two electrons that are released by zinc will be gained by the Cu 2+ ions (reduction). The Cu2+ ions become Cu atoms. Total equation: Zn (s) + CuSO 4 (aq) --> Cu (s) + ZnSO 4 (aq)
