Answer:

Explanation:

Example #1: How many moles of oxygen will occupy a volume of 2.50 L at STP? Standard ... What is the volume of gas at 2.00 atm and 200.0 K if its original volume was ... P2 = 2.00 atm 2.000tm) 273k. T=273k. 200.0k. Tz= 200.0k. V, = 200.0L ... A gas has a pressure of 0.370 atm at 50.0°C. What is the pressure at standard.

Determine if the bond between each pairs of atoms would be pure covalent, polar covalent, or ionic. n and se
Sveta_85 [38]

Types of Bonds can be predicted by calculating the difference in electronegativity.

If, Electronegativity difference is,

 

                Less than 0.4 then it is Non Polar Covalent Bond

                

                Between 0.4 and 1.7 then it is Polar Covalent Bond

            

                Greater than 1.7 then it is Ionic

 

For N and Se,

                    E.N of Nitrogen         =   3.04

                    E.N of Selenium        =   2.55

                                                   ________

                    E.N Difference             0.49          (Weakly Polar Covalent)


As you have not provided remaining pairs, so if you have any of them, follow the method as mentioned above.

A) Which of the following equations model the law of conservations of mass? Ca + 2HCI - H2 + CaCl2 or
nydimaria [60]

Answer:

The first equation

Explanation:

For these problems, it is best to label and record how many of each element are on each side of the equation. The first equation has 1 Ca, 2H, and 2Cl on both sides while the second equation has 3H on the left and 2H on the right making the second equation incorrect.

Give the value of the quantum number ℓ, if one exists, for a hydrogen atom whose orbital angular momentum has a magnitude of 6√(
MakcuM [25]

Answer:

For this angular momentum, no quantum number exist

Explanation:

From the question we are told that

   The magnitude of the angular momentum is  L  = 6\sqrt{\frac{h}{2 \pi} }

The generally formula for Orbital angular momentum is mathematically represented as

           L  = \sqrt{(l * (l + 1)) } *  \frac{h}{2 \pi}

Where l is the quantum number

now  

We can look at the given angular momentum in this form as

      L  = 6\sqrt{\frac{h}{2 \pi} }    =  \sqrt{36}  * \sqrt{\frac{h}{2 \pi}} }

comparing this equation to the generally equation for Orbital angular momentum

     We see that there is no quantum number that would satisfy this equation
