Answer: The mass percent of NaCl is 6.3 % and mass percent of water is 93.7%.

Explanation:

To calculate the mass percent of element in a given compound, we use the formula:

\text{Mass percent }=\frac{\text{Mass of given compound}}{\text{Total mass}}\times 100

Given :

Mass of NaCl = 13.5 g

Mass of water = 250.0 g

Putting values in above equation, we get:

\text{Mass percent of}NaCl=\frac{13.5}{13.5+250.0}\times 100=6.3\%

Hence, the mass percent of NaCl is 6.3 %.

Putting values in above equation, we get:

\text{Mass percent of water=\frac{200}{13.5+250.0}\times 100=93.7\%

Hence, the mass percent of water is 93.7 %.

Let us calculate the structure of the electric shells of the Al atom. It has an atomic number of 13, so it has 13 electrons. The first 2 go to the first hell. The next 8 need to go to the second shell and the last 3 ones would go to the outermost shell. The outer shell, that is the most important one for chemical reactions, has thus 3 electrons. An atom always tries to have a completed outer shell (with either 2 or 8 atoms). It is easier for a cell to have a charge of +3 than a charge of -5 (smaller absolute value) and thus the Aluminum atom will try to get rid of the 3 electrons. In this process, it loses negative charge thus it will become positively charged. Hence, the correct answer is that it will prefer to lose 3 electrons and become positively charged.

In the nuclear transmutation, 168O (?, α)137N, what is the bombarding particle? In the nuclear transmutation, O (?, )N, what is
xeze [42]

Answer:

The bombarding particle is a Proton

Explanation:

A Nuclear transmutation reaction occurs when radioactive element decay, usually converting them from one element/isotope into another element. Transmutation is the process which causes decay, generally, alpha or beta.

¹⁶₈O(P,alpha) ¹³₇N, can be written as

¹⁶₈O + x goes to ¹³₇N + ⁴₂He

Where x can be anything, balancing the equation in order to give us the correct amount of proton number and nucleus number

16 + x = 13 + 4

x = 17 – 16 = 1, Hence we can say that x = ¹₁P

<u>¹⁶₈O + ¹₁P goes to ¹³₇N + ⁴₂He</u>

Here we can clearly see the bombarding particle is ¹₁P (proton). The ejected particle being ⁴₂He which is also known as an alpha particle
