Na releases 1 electron to be stable
Cl requires 1 electron to be stable
both are ionic bonded to be stable
Answer:
9 days, or 3 half-lives
Explanation:
5.2x10^5=520000
6.5x10^4=65000
65000/520000=1/8, or 3 half-lives
3x3=9 days
I'm not the greatest at Chem but this seems more like math than Chem :)
Given mass of KNO₃=346g
Molar mass of KNO₃=(39.098)+(14)+(15.99*3)=101.068gmol⁻¹
Volume of Solution=750ml=0.75dm³
Molarity=(mass of solute/molar mass of solute)*(1/volume of sol. in dm³)
=(346/101.068)*(1/0.75)
=4.56 mol dm⁻³
Answer:
25°C
Explanation:
To convert from Kelvin to Celcius we can use this equation:
Temperature in Kelvin - 273 = Temperature in Celcius
298K - 273 = 25°C
