You would get four moles of magnesium nitrate :) you would have to
“ ?molesmg(oh)2 = 8molmg(no3)2 x molmg(oh)2 / 2molhno3 = 4 moles of magnesium nitrate :))) hopefully this helps! <3
Answer:
28 is great.......... it should be snSwer
Answer:
169.67Ω
Explanation:
This question is asking for the inductive reactance, which is calculated as follows:
X(L) = 2πfL
Where;
X(L) = inductive reactance (Ω)
f = frequency (Hz)
π = 3.142
L = inductance (Henry)
Given the information provided, f = 60Hz, L = 0.450H
X(L) = 2πfL
X(L) = 2 × 3.142 × 60 × 0.450
X(L) = 6.284 × 60 × 0.450
X(L) = 6.284 × 27
X(L) = 169.668
X(L) = 169.67Ω
The number of transferred electrons to form the ionic bond in one formula unit of each compound is as below
NaCl = 1 electron
CaS = 2 electrons
BaO= 2 electrons
KBr=1 electrons
LIF = 1 electron
explanation
ionic bond is formed between a metal and a nonmetal . This bond is formed when electron are transferred between cation and anion. To know how many electrons transferred you look the oxidation state of the metal.
for example
in NaCl only one electrons is transferred since Na is in oxidation state of +1. Na donate the one electron to Cl to form an ionic bond. Ba is in oxidation state of 2+ and hence it donate the two electrons to O to form ionic bond.
