What are elements 90-103 called on the periodic table?

A 6.35 l sample of carbon monoxide is collected at 55.0◦c and 0.892 atm. What volume will the gas occupy at 1.05 atm and 59.0◦c?

Sonja [21]

Answer : The final volume of gas will be, 5.46 L

Explanation :

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

where,

$P_1$ = initial pressure of gas = 0.892 atm

$P_2$ = final pressure of gas = 1.05 atm

$V_1$ = initial volume of gas = 6.35 L

$V_2$ = final volume of gas = ?

$T_1$ = initial temperature of gas = $55.0^oC=273+55.0=328K$

$T_2$ = final temperature of gas = $59.0^oC=273+59.0=332K$

Now put all the given values in the above equation, we get:

$\frac{0.892atm\times 6.35L}{328K}=\frac{1.05atm\times V_2}{332K}$

$V_2=5.46L$

Thus, the final volume of gas will be, 5.46 L

3. What is the shape of 3p atomic orbital? (1 point)

sukhopar [10]

Option B

dumbbell is the shape of 3p atomic orbital

Explanation:

Atomic orbitals are three-dimensional places inside an atom where there is a tremendous chance of detecting electrons. The p orbital, which develops in complexity and ought 2 spaces encompassing the atom core, or is defined as possessing a dumbbell pattern. The 3p atomic orbital is at energy level 3, as seen by the number 3 filed ere the character.

These orbitals have identical appearances but are arranged asymmetrically in location. p orbitals are wavefunctions with l=1. They ought an angular frequency that is ununiform at each angle. They have an appearance that is much defined as a "dumbbell".

Which are the more common types of solutions?

aniked [119]

Hey there! :

1) Solid Solutions

Solid solutions are formed only by solutes and solid solvents. In everyday life, the main examples of this type of solution are metallic alloys.

2) Liquid Solutions

Liquid solutions have liquid solvent, usually water, and solutes can be solid, liquid or gaseous.

3) Gaseous solutions

This kind of solution is formed by the only mixture of gases. Air is an example, as its approximate composition is 78% nitrogen gas, 21% oxygen gas and 1% of other gases.
