At sufficiently high temperature, Mg + H2O = MgO + H2.
In the reaction Mg + HO → Mg + H, the oxidation state of each hydrogen atom in H (which is diatomic hydrogen, H₂) is 0. This is because in its elemental form, hydrogen exists as H₂, and elements in their natural state have an oxidation state of zero.
To balance the combustion reaction of propane (C3H8), which produces carbon dioxide (CO2) and water (H2O), we start with the unbalanced equation: C3H8 + O2 → CO2 + H2O. Balancing it gives us: C3H8 + 5 O2 → 3 CO2 + 4 H2O. Therefore, the coefficient for O2 in the balanced equation is 5.
This is the chemical reaction for burning of propane.
The balanced chemical equation is C3H8 + 5 O2 ⟶ 3 CO2 + 4 H2O. This means that when one molecule of propane (C3H8) reacts with five molecules of oxygen (O2), it produces three molecules of carbon dioxide (CO2) and four molecules of water (H2O).
zinc nitrate + sodium hydroxide yields sodium nitrate and zinc hydroxide( white precipitate)
C3h8 + 5o2 --> 3co2 + 4h2o
C3h8 + 5o2 -> 3co2 + 4h2o
The reaction between zinc (Zn) and magnesium chloride (MgCl2) would yield zinc chloride (ZnCl2) and magnesium (Mg).
The chemical equation C3H8 + 5O2 -> 3CO2 + 4H2O represents the combustion of propane (C3H8) with oxygen (O2) to produce carbon dioxide (CO2) and water (H2O).
C3H8 + 5O2 --> 3CO2 + 4H2OThis is a combustion reaction with propane. Always carbon dioxide and water as products.
2C3H8 + 10O2 = 6CO2 + 8H2O

Magnesium hydroxide plus hydrochloric acid yields magnesium chloride plus water. Mg(OH)2 + 2HCl = MgCl2 + 2H2O
You have to burn C3H8 in O2. You get 3CO2 plus 4H2O. So to burn one mole of C3H8, you need 5 moles of O2. That means you need one fifth of C3H8 as compared to O2. So you need 0.567/5 = 0.1134 moles of C3H8. Hence the answer.
C3h8 + 5o2 -----> 3co2 + 4h2o
Silver nitrate plus potassium iodide yields silver iodide plus potassium nitrate.
