Reactants are the raw ingredients before the experiment and products are what the the experiment produces. For instance if you ignite hydrogen and oxygen then the Reactants are hydrogen and Oxyhen and the Products are water (formed form the Hydrogen and Oxygen) and heat.
Wood ashes contain potassium hydroxide (potash) which will be beneficial to the sweetcorn as it develops its fruit, as nitrates are used for leaf growth, potassium is used for fruit,seed production and phosphorous is used by root growth so it is ok to feed sweetcorn with wood ashes
I think it's charcoal. I saw it on tv that they have to cover all the wood with galvanized iron (yero) and let it stay there for 3 days. It said that if there is air, it will fail. It will turn into ashes instead of charcoal.
yes because the ash helps them to get the nutrients they need and helps them grow. It is because the wood comes from a cut down tree and if a tree is a plant, even though it is burnt it still has the oxygen it needs to give out.
