The reason the waste of nuclear power plants is so dangerous is it's radioactive, and in some cases, still nuclear.

1. Biodiversity = the variance of plant and animal species within an environment
With biology words, the best way to figure out the definition is to break it up into smaller words. In biodiversity, there is "bio" and "diversity". Bio means life and another word for diversity is variety. Therefore, in biodiversity, there is a variety of life or life forms. This answer choice best suits that definition.

Answer:

4 protons, 5 neutrons, 4 electrons to have the neutral Be atom

the only way to make a negative Be is to have more than 4 electrons

Explanation:

Make a neutral Beryllium atom by adding protons, neutrons and electrons. Now, what would you do to make a

beryllium atom with a negative charge?

Be has an atomic number of 4, an atomic mass 9

its atomic number tells us it has 4 protons, with a +4 charge

its atomic mass = neutrons + protons, so it has 5 neutrons with no charge

its neutral atom will have 4 electrons each with a negative charge to balance the +4 total proton harge.

4 protons, 5 neutrons, 4 electrons to have the neutral Be atom

to make a negative Be species, it still must have an atomic number of 4,

or it is not Beryllium

so the only way to make a negative Be is to have more than 4 electrons

In the simulation, open the Custom mode. The beaker will be filled to the 0.50 L mark with a neutral solution. Set the pH to 11.

Mila [183]

Answer:

Hydroxyl ion concentration is $5.08\times10^{-11}M$ .

Explanation:

From the given,

pH of the solution = 11.30

pH+pOH = 14

11.30 + pOH = 14

pOH = 14-11.30 = 2.7

The pOH of the solution is 2.7

<u>Concentration of hydroxyl ion:</u>

$2.7= -log[OH^{-}]$

$log[OH^{-}]= -2.7=5.08\times10^{-11}M$

Therefore, hydroxylion concentration is $5.08\times10^{-11}M$ .
