The pencil attached to the negative terminal of the battery collects hydrogen gas while the one connected to the positive terminal collects oxygen.
Smaller than; less of it will dissolve before the solution is saturated
Lava I think try that hope it helps :)
Answer is D, they are compressible
NaBH 4 reacts with water and alcohols, with the evolution of hydrogen gas and the formation of the corresponding borate, the reaction being especially fast at low pH. Nevertheless, alcohol, often methanol or ethanol, is generally the solvent of choice for sodium borohydride reductions of ketones and aldehydes.
Methanol poses a greater risk because it is metabolized into a very toxic substance i.e. formic acid and also highly poisonous.
What is Methanol?
Methanol is a promising energy carrier because, as a liquid, it is easier to store than hydrogen and natural gas. Its energy density is, however, lower than methane, per kg.
