Answer:
A flame test of a colorless solution gives a bright yellow color. When reacted with AgNO, a white precipitate forms that dissolves when HNO, is added.
Answer:
Option E
Explanation:
As work is dot product of force and displacement
W=FdCos0
As Cos 0=1 so W=F.d(1)
W=F.d
as Cos 90=0 so no work will be done when angle between force and displacement is 90 degree. At angle between force and displacement is 180 degree then negative value com as Cos 180= -1
Hey there!
Your answer is B. MgCl.
This is because this isn't an actual existing compound.
Water (H₂O) and magnesium chloride (MgCl₂) are both real compounds, but the number of electrons does not line up to make MgCl possible.
Hope this helps!
