Answer:

Option D. equation D

Explanation:

Positron is simply a beta plus decay or superscript 0 e subscription 1 (0 1 e).

Now, let us consider the options given:

Option A is emitting alpha decay

Option B is emitting beta minus decay.

Option C is emitting beta minus decay.

Option D is emitting beta plus decay also known as Positron.

A gas occupies 547 L at 331K. Find its volume at 376K. You must show all of your work to receive credit. Also, name the gas law
zysi [14]

621.4L

Explanation:

Given parameters:

Initial volume = 547L

Initial temperature = 331K

Final temperature = 376K

Unknown:

Final volume = ?

Solution:

The appropriate gas law to use is the Charles's law.

The Charles's law shows the relationship between the volume and temperature of a gas under constant pressure.

The law states that "The volume of a fixed of a gas varies directly as its absolute temperature if the pressure is constant".

Mathematically;

    \frac{V_{1} }{T_{1} }  = \frac{V_{2} }{T_{2} }

 V₁ is the initial volume

 T₁ is the initial temperature

 V₂ is the final volume

 T₂ is the final temperature

Since the unknown is the final volume, we make it the subject of the expression;

   V₂ = \frac{V_{1} }{T_{1} }  x T_{2}  = \frac{547}{331 }  x 376

 V₂ =  621.4L

Is H3O+ polar or non polar? (explain please.)?
pishuonlain [190]
The overall molecule is Polar because the shape of the molecule is Trigonal Pyramidal, which means it has the lone pair electrons. Becuase of the lone pair the pulling is unequal.   

H3O+ has 3 polar bonds. 
To know if the bonds are polar or nonpolar find the difference of the element's electronegativity charge. 
H has electronegativity charge of 2.2, and O has 3.4.
Always subtract the smaller number from the greater one. 
So 3.4 - 2.2 = 1.2 
If the difference is from 0-0.4 the bond is nonpolar, but if it's from 0.5-1.9 the bond is polar. 
So, 1.2 is polar bond. So H3O+ has 3 polar bonds, and the overall molecule is polar too. 

A simple way to know if it's polar or nonpolar is to draw the lewis dot structure, and use VSEPR.
