Ion with a 1+ charge. The atom would normally be neutral, since it has the same number of electrons as it does protons; removing an electron leaves one more proton than electron. Since protons are positive and there's one more of them than electrons in the new ion, it has a 1+ charge.
Answer : Phenolphalien turn pink in the presence of a base.
Phenolphthalien : It is an indicator which is used in the acid-base titration.
In acidic medium, the phenolphthalien is colorless and the pH will be less than 7.
In basic medium, the phenolphthalien is pink in color and the pH will be greater than 7.
Phenolphthalien is slightly soluble in the water and highly soluble in alcohols.
Hence, the phenolphalien turn pink in the presence of a base.
Answer:
Captive breeding
Explanation:
Endangered species, such as the Black Rhino, Saola, Cross River Gorrillas, the Blue Whale, and a host of others, are species that are critically under the verge of extinction either as a result of the destruction of their habitat or poaching/overhunting, which has really led to steep decline in their population.
Several attempts have been made and ate being made to ensure the preserve and protect these endangered species form going extinct.
However, the best of such measures or practices is arguably referred to as Captive Breeding.
Captive breeding involves the capturing of some of these endangered species and transporting them to enclosed and monitored facilities such as zoos in other to promote the increase preservation and survival of these species and ensuring they don't go extinct.
In most cases, when a considerable increase in population in these facilities is established through breeding, some of them are later on reintroduced to their natural habitat in the wild. This do not only ensure biodiversity, it also ensures the population of the endangered species to grow and avoid such species from going extinct.
* Answer: 448.056 meters *
——
1 yard = .9144 meters (according to Google)
100 yards= 91.44 meters
——
100*4.9= 490 yards
490 yards = 448.056 meters
* 4.9 Football fields= 448.056 meters *
I hope this helps! :)
