A) divide by 100. A meter is 100 centimeters so that’s how you can tell
Answer: -
¹⁰B has the same number of neutrons as ⁹Be
Explanation: -
Mass number of ⁹Be = 9
Atomic number of ⁹Be = 4
Number of neutrons of ⁹Be = mass number - atomic number
= 9 - 4 = 5
Mass number of ¹⁰B = 10
Atomic number of ¹⁰B= 5
Number of neutrons of ¹⁰B= mass number - atomic number
=10 - 5 = 5
Particles vibrate when frozen when it boils it moves like you had 4 monsters in the morning
We have the compound: KSCN, Potassium thiocyanate, in an aqueous solution.
The dissociated reaction of the salt:
KSCN (aq) => K+ + SCN-
It has 2 ions. One of them is the potassium ion, K+ (cation) and the other one is the thiocyanate ion, SCN- (anion).
Answer:
K+, the potassium ion
SCN-, the thiocyanate ion
