Answer:Iron combines with oxygen to produce rust, which is the compound named iron oxide
Explanation:
Answer:
8 OH⁻(aq) + Mn(s) ⇒ MnO₄⁻(aq) + 4 H₂O(l) + 7 e⁻
Explanation:
Let's consider the following oxidation half-reaction that takes place in basic aqueous solution.
Mn(s) ⇒ MnO₄⁻(aq)
First, we will perform the mass balance. We will add 4 H₂O to the products side and 8 OH⁻ to the reactants side.
8 OH⁻(aq) + Mn(s) ⇒ MnO₄⁻(aq) + 4 H₂O(l)
Finally, we will perform the charge balance by adding 7 electrons to the products side.
8 OH⁻(aq) + Mn(s) ⇒ MnO₄⁻(aq) + 4 H₂O(l) + 7 e⁻
Answer:
SI unit: kg/m³
but g/cm³ is commonly used
Explanation:
Due to the lack of information provided, the best I can give you is this:
In Chemistry, the letter c most commonly refers to specific heat, which is present in the ratio J/g°C.
Hope it helps :)
A short circuit is an easier path for electron flow
