Their number of atoms.
Abundance of radium in the earth crust: 9.10-10 mg/kg Abundance of radium in the sea water: 8,9.10-14 mg/L
The empirical formula is CH2
Mg(NO3)2 1 magnesium atom, 2 nitrogen atoms, and 6 oxygen atoms Mg(NO3)2 because the charge on Mg is +2 and the charge of NO3 is -1 so you would need to balance. Magnesium has 2+ and Nitrate is one of the common polyatomic ions: NO3^1- Combine them both: Mg1(NO3)2 ===> Mg(NO3)2
0.1 mg
They have two nuclear ☢️
they are in group two
Mg2+
No.
yes
Mg-24
I am guessing you mean .125 mg of Synthroid and this is the same as 125 micorgrams. This is a common dose. 125 mg is 125,000 micrograms.
.25 mg .5 Mg 1 Mg 2 Mg These Are the Most Common Doses] It comes in 3 Mg, and 6 Mg, This is being introduced to the American markets.
Their number of atoms.
2400 mg/day is a common upper dose.
the answer is there number of atoms
most common military method of expressing direction
