Answer:
Explanation:
-The Atomic Radius of an element is the distance between the center of an atom
-nucleus and its outermost, or valence electrons. ... These changes are caused by the interaction between the positive charge of the protons
- nucleus and the negative charge of all the atom's electrons.
Answer:
50 N
Explanation:
Because It not in motion means it standing still. So the answer is 50 Newton
The boxed diagram name is known as the Periodic Table of Elements in which elements are periodically organized by their atomic number.
The answer is A. 1350
(ALL NUMBERS Except the grams is given from the equation)
18.21mol HNO3/1 * 1mol MgN206/2mol/ 2mol HNO3 * (molar mass-->)148.30 MgN206/ 1mol MgN2O6
You multiply 18.21HNO3* 1mol MgN2O6 * 148.30MgN2O6
Then divide it by the 2mol HNO3 to get 1350
Answer:
Molality for this solution is 0.98 mol/kg
Explanation:
ΔT = Kf . m . i
Freezing point depression, here
ΔT = Freezing point of pure solvent - Freezing point of solution
i = Van't Hoff factor.
This solute, the amino acid glycine does not ionize, so the i in this case is 1
Let's replace the data given
0° - (-1.83°C) = 1.86 °C/m . m . 1
1.83°C = 1.86 °C/m . m . 1
1.83°C / 1.86 m/°C = 0.98 m
