Three isotopes of sulfur are sulfur-32, sulfur-33, and sulfur-34. write the complete symbol for each isotope, including the atom

Maurinko [17]

Sulfur is an element in the periodic table that has a chemical symbol of S. This element is the 16th element in periodic table. This means that the atomic number or number of protons in the nucleus of the atom is equal to 16.

The number following the name of the element is the mass number. The following are the complete symbol that are arranged as follows:
chemical symbol - atomic number - mass number

*Sulfur-32
S - 16 - 32

*Sulfur-33
S - 16 - 33

*Sulfur-34
S - 16 - 34

Which of these statements describes this mathematical equation?

salantis [7]

Answer:

The final pressure of a gas is inversely proportional to the volume change and directly proportional to temperature

Explanation:

Given

$\frac{P_1V_1}{T_1} = k$

Required

Interpret

$\frac{P_1V_1}{T_1} = k$

Multiply both sides by T1

$T_1 * \frac{P_1V_1}{T_1} = k * T_1$

$P_1V_1 = kT_1$

Divide both sides by V1

$\frac{P_1V_1}{V_1} = \frac{kT_1}{V_1}$

$P_1 = \frac{kT_1}{V_1}$

This can be rewritten as:

$P_1 = k\frac{T_1}{V_1}$

In the above expression; k is a constant of proportionality.

So, the equation can be written as variation as follows:

$P_1\ \alpha\ \ \frac{T_1}{V_1}$

To interpret:

<em>P varies directly to T (the numerator) and inversely to V (the denominator).</em>

What is the scientific notation of 36000x10 ex.10?

Vedmedyk [2.9K]

Answer:

3.6 times 10^4

Explanation:

Scientific notation is between 1-9. So, we move 36000 to 4 decimal places. SO it would be 3.6 times 10^4. Scientific Notation always has the base of 10 . Enjoy :)
