Answer: Potassium to fluorine, fluorine to nitrogen, bromine to hydrogen, carbon to hydrogen, lithium to chlorine, sodium to chlorine.
Explanation:
Ionic bond is greater when the electronegativity difference existing between the two atoms are large causing the bonding to be more polar.
Answer:
4.35 * 10^-8 M
Explanation:
Since the concentration of the hydronium ion= 2.3 X 10^-7 M
And we know that;
[H3O^+] [OH^-] = 1 * 10^-14
[H3O^+] = concentration of the hydronium ion
[OH^-] = concentration of the hydroxide ion
So;
[OH^-] =1 * 10^-14/[ H3O^+]
But [H3O^+] = 2.3 X 10^-7 M
[OH^-] = 1 * 10^-14/2.3 X 10^-7
[OH^-] = 4.35 * 10^-8 M
Answer:
The final volume of the balloon is = 28.11 L
Explanation:
Initial pressure 
= 1.03 atm = 104.325 K pa
Initial temperature 
= 26 °c = 299 K
Initial volume 
= 22.4 L
Final temperature 
= 22 °c = 295 K
Final pressure 
= 0.81 atm = 82 K pa
We know that
Put all the values in above formula we get
= 28.11 L
This is the final volume of the balloon.
Answer:
Option (2)
Explanation:
Since the amount of each sample is the same, we are looking for the metal with the greatest density, which is copper.
I believe it is A because the plant is offering protection while the bacteria is converting it in to nitrogen that the plant can use!
