Which of the following represents the chemical reaction of hydrobromic acid and chlorine to produce hydrochloric acid and bromine?
A.
hydrobromic acid + chlorine → hydrochloric acid + bromine
B.
hydrobromic acid + hydrochloric acid → chlorine + bromine
C.
hydrochloric acid + bromine → hydrobromic acid + chlorine
D.
bromine + chlorine → hydrochloric acid + hydrobromic acid

Option A. hydrobromic acid + chlorine → hydrochloric acid + bromine.

Explanation:

In the above reaction, hydrobromic acid react with chlorine atom to produce hydrochloric acid and bromine. In this reaction, hydrogen of hydrobromic acid make bond with chlorine atom because chlorine is very reactive so they made a bond with each other forming hydrochloric acid and bromine atom.

a adaptation is when organism changes itself to fit the environment

ex. when its cold outside i wear a jacket

hello everyone my name is nevaeh, i know everyone needs in some way, shape, or form and i am willing to provide. i set up a google classroom where people can ask me questions and get on work. no question is a stupid question so do not be afraid to ask. i usually only focus on core subjects but if you ask i will with other specialized subjects. i can do essays all the way to power points : )

my google classroom is the code is 7hr2k4

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
