A gas has a of 590 mi. At a temperature What volume will the gas occupy at 30.0öc.1 Which gas law is this

scoray [572]

The given question is incomplete. The complete question is:

A gas has a volume of 590 ml at a temperature of $0^0C$ .What volume will the gas occupy at $30.0^0C$ . Which gas law is this?

Answer: 655 ml , Charle's Law

Explanation:

To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

where,

$V_1\text{ and }T_1$ are the initial volume and temperature of the gas.

$V_2\text{ and }T_2$ are the final volume and temperature of the gas.

We are given:

$V_1=590ml\\T_1=0^oC=(0+273)K=273K\\V_2=?\\T_2=30.0^0C=(30+273)K=303K$

Putting values in above equation, we get:

$\frac{590}{273}=\frac{V_2}{303}\\\\V_2=655ml$

Thus the volume at $30.0^0C$ is 655 ml

Period 6 is unusual in several ways.(a) It is the longest period in the table. How many elements belong to Period 6? How many me

Nookie1986 [14]

Period 6 is unusual in several ways.

Lanthanum (La), hafnium (Hf), tantalum (Ta), tungsten (W), rhenium (Re), osmium (Os), iridium (Ir), platinum (Pt), gold (Au), and mercury are the period 6 transition metals (Hg).

<h3>Why Period 6 is unusual ?</h3>

The group of fifteen metallic chemical elements with atomic numbers 57 through 71, from lanthanum to lutetium, is known as the lanthanide or lanthanoid series (IUPAC nomenclature).

The phrase "rare-earth elements" refers to these fifteen elements as well as the chemically related elements scandium and yttrium.

Because it comprises a maximum of 32 elements, the sixth period is referred to be the longest period.

The nonmetals oxygen (O), sulfur (S), and selenium (Se), as well as the metalloid tellurium ( Te ) and the metal polonium, are classified as chalcogens in group 6A (or VIA) of the periodic table (Po).

The periodic table has a group of elements designated as Group 6 in IUPAC style. Chromium, molybdenum, tungsten, and sea-borgium are its constituent elements. While chromium, molybdenum, and tungsten are refractory metals, all of these are transition metals.
