If any reaction happens and we want to know whether hydrogen is evolved or not by bringing a burning splinter towards the place where the reaction happens. If hydrogen is evolved in that reaction the burning splinter will burn with a pop sound.

The sexual mode of reproduction is considered to be better than the asexual mode of reproduction. This is because, in the asexual mode of reproduction, the only single parents give rise to another offspring which is exactly similar to the parent as it passes its genetic material to offspring. So there are no chances of including variation in progeny. In the sexual mode of reproduction, there... more are fusion gametes of two parents male and female. As a result, offspring has the genetic material of both and so, there is greater variation among offsprings. They are better and adaptive to their environment due to variations introduced in them during meiosis cell division and crossing over. So they are more suited to the environment they live in. So. organisms born through sexual mode of reproduction are better and sexual mobe of reproduction is better than an asexual mode of reproduction
The essence of hybridization is the fusion during fertilization of genotypically different sex cells and the development from the zygote of a new organism that combines the hereditary disposition of the parents.in biology"""
Orbital hybridization (or hybridization) is the concept of mixing atomic orbitals into new hybrid orbitals with different energies, shapes, etc., than the component atomic orbitals. Hybrid orbitals are very useful in the explanation of molecular geometry and atomic bonding properties and are symmetrically disposed in space. in chemistry"""
The most effective way to test for CO2 is to bubble the gas through "limewater", a diluted solution of calcium hydroxide (slaked lime). When you bubble carbon dioxide through the solution, it forms a solid precipitate of calcium carbonate – chalk or limestone.
