Answer:
<u>1997.84</u>
Explanation:
(22.6g)(.52J/gC)(170C)
eliminate the respective variables
and you will only have Joules left
multiply it all
u get 1997.84
the force between the electron and the proton.
a) Use F = k * q1 * q2 / d²
where k = 8.99e9 N·m²/C²
and q1 = -1.602e-19 C (electron)
and q2 = 1.602e-19 C (proton)
and d = distance between point charges = 0.53e-10 m
The negative result indicates "attraction".
the radial acceleration of the electron.
b) Here, just use F = ma
where F was found above, and
m = mass of electron = 9.11e-31kg, if memory serves
a = radial acceleration
the speed of the electron.
c) Now use a = v² / r
where a was found above
and r was given
<span> the period of the circular motion.</span>
d) period T = 2π / ω = 2πr / v
where v was found above
and r was given
The reactions that will take place will generate Zinc salts that will
taint the food. Excessive levels of these salts can cause sickness, so
it is very important to ensure food hygiene standards are met by keeping
acidic foods away from damaging materials like zinc that will erode and
get into the food.
Yes, the atomic radius increases as you move down a group of elements.
this is true
going down leads to valence electrons that are further away from nucleus -> less electrostatic attraction -> less pull towards nuc. -> greater radius/volume taken
Hi, I am Rosy67 and im here to help.
I have read your sentence and i believe the answer is the following;
