bromothymol blue turns yellow betwwen then pH levels of 2 and 6
The charge of proton and electron is equal in magnitude that is 
. The distance between electron and proton is 
or 
.
Force exerted on electron by proton is calculated as follows:
Here, k is Coulomb's constant, 
is charge on proton, 
charge on electron and r is distance between them.
Putting the values,
Now, according to second law of Newton,
Here, 
is mass of electron and a is acceleration.
Also, 
Rearranging,
Thus, the acceleration of an electron in this atom is 
.
Yes they break down what they are made of and figure it out.
Answer:
A suspension is a heterogeneous mixture of a finely distributed solid in a liquid. The solid is not dissolved in the liquid, as is the case with a mixture of salt and water. Suspension.
Explanation:
Common examples of suspension include the mixture of chalk and water, muddy water, the mixture of flour and water, a mixture of dust particles and air, fog, milk of magnesia, etc. ... Particles of the suspension are large enough to scatter the rays of light and the path of ray is visible through it.
