1. In general, the nucleus of a small atom is stable. Therefore, over very short distances, such as those in a small nucleus,

postnew [5]

<h3>1. Answer;</h3>

a. the strong nuclear force is much greater than the electric force.

<h3>Explanation;</h3>

For an atom to be stable it means it has enough amount of binding energy to hold its nucleus together permanently.
Therefore, an unstable atom lacks enough amount of binding energy to hold its nucleus permanently and thus undergoes decay to achieve stability. Unstable atoms are therefore referred to being radioactive.
Small atoms are stable; this is because they have equal number of protons and neutrons and thus the protons and neutrons fill up energy levels while maximizing the strong force binding the nucleus together.

<h3>9. Answer;</h3>

b. change into a different element altogether.

Uranium-238 undergoes alpha decay. Therefore, uranium-238 will change into a different element altogether.

<h3> Explanation;</h3>

Unstable atoms undergo radioactive decay in order to achieve stability of their nucleus.
Uranium-238 is an example of such atom, which may undergo decay to achieve stability.
Alpha decay is one of the types of decays, others being beta decay and gamma decay. In alpha decay the radioactive isotope undergoes decay such that its mass number is decreased by four and its atomic number is decreased by two.
Therefore, Uranium-238 undergoes alpha decay to form a different element whose mass number is 234 and atomic number is 90, known as thorium-234.

Determine the formula weight of BeCl₂.

tia_tia [17]

Be= Beryllium= weight 9.01
Cl= Chlorine= weight 35.45
Since there are 2 Chlorine, you have to add Chlorine twice.
9.01 + 35.45 + 35.45= 79.91

Answer: 79.91

Suppose you have been given the task of distilling a mixture of hexane + toluene. Pure hexane has a refractive index of 1.375 an

miv72 [106K]

Explanation:

The given data is as follows.

Refractive index of mixture = 1.456

Refractive index of hexane = 1.375

Refractive index of toulene = 1.497

Let mole fraction of hexane = $x_{1}$

and, mole fraction of toulene = $x_{2}$

Also, $x_{1} + x_{2} = 1$

or, $x_{1} = 1 - x_{2}$

Hence, calculate the mole fraction of hexane as follows.

refractive index mixture= mole fraction hexane × ref index hexane + mole fraction toluene × ref index toluene.

1.456 = $(1 - x_{2}) \times 1.375 + x_{2} \times 1.497$

1.456 = $1.375 - 1.375x_{2} + 1.497x_{2}$

0.081 = $0.122x_{2}$

$x_{2}$ = $\frac{0.081}{0.122}$

= 0.66

Since, $x_{1} = 1 - x_{2}$

= 1 - 0.66

= 0.34

Thus, we can conclude that mole fraction of hexane in your sample is 0.34.

If x is a string, then x = new String("OH"); and x = "OH"; will accomplish the same thing. Group of answer choices True False

Vinvika [58]

Answer:

True is the correct answer to the above question.

Explanation:

If x is a string then it can be assigned by the help of two ways in java:
By the help of constructor:- When we write " x = new String("OH");", then it will create a pass a string "OH" into the constructor. It is because the String is a class in java and x is an object created by the constructor of the String class.
With the help of assigning: The "x= OH", which assigns the value of x which is an object of String class it can also use the constructor to initialize the "OH" string on the class.
The above question states the two scenarios which are defined above. Hence the question statement is true.
