Explain your reasoning for your formula prediction for Ba+2 and S-2. A neutral molecule requires equal numbers of cations and an

ions. Atoms will not combine unless their ions have an equal but opposite charge. The total charge of cations plus anions must equal zero. all of the above

Answer:

<em>BaS would be a stable neutral molecule!</em>

<em>Reason:- <u>All of the above</u>.</em>

<em>Explanation</em><em>:</em>

In order to form a neutral molecule it's necessary to balance their charge first, The given components i.e. Ba2+(cation) and S2-(anion) have equal and opposite charges, when they combine they form predominantly ionic compound i.e. Sulphur partly shares it's 2 electrons with Barium and forms Barium sulphide.

Lithium has two stable isotopes with masses of 6.01512 amu and 7.01600 amu. The average molar mass of Li is 6.941 amu. What is t
Dvinal [7]

Answer :  The percent abundance of Li isotope-1 and Li isotope-2 is, 6.94 % and 93.1 % respectively.

Explanation :

Average atomic mass of an element is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.

Formula used to calculate average atomic mass follows:

\text{Average atomic mass }=\sum_{i=1}^n\text{(Atomic mass of an isotopes)}_i\times \text{(Fractional abundance})_i   .....(1)

Let the fractional abundance of Li isotope-1 be 'x' and the fractional abundance of Li isotope-2 will be '100-x'

For Li isotope-1 :

Mass of Li isotope-1 = 6.01512 amu

Fractional abundance of Li isotope-1 = x

For Li isotope-2 :

Mass of Li isotope-2 = 7.01600 amu

Fractional abundance of Li isotope-2 = 100-x

Average atomic mass of Li = 6.941 amu

Putting values in equation 1, we get:

6.941=[(6.01512\times x)+(7.01600\times (100-x))]

By solving the term 'x', we get:

x=694.048

Percent abundance of Li isotope-1 = \frac{694.048}{100}=6.94\%

Percent abundance of Li isotope-2 = 100 - x = 100-6.94 = 93.1 %

Distinguish between accuracy and precision in measurements
nignag [31]

The accuracy is associated with magnitude of fractional error or relative error in that measurement

the precision of a measurement is associated with least count of the measuring instrument.

precision does not mean accuracy but both are highly demanded while making measurements in physics.

1) <span>The cost of not moving forward is extremely high, so they opposed the plan, as they think it would affect US economy

2) </span><span>Nuclear waste disposal capability is an environmental imperative, so their environment would be polluted by very radioactive materials.

3) </span>Demand for new nuclear plants also demands disposal capability which supports national security but again, their site will be no longer for them. But unfortunately, <span>Extensive studies consistently show Yucca Mountain to be a sound site for nuclear waste disposal so the plan can't be abolished.
