<span>Two things determine momentum. Speed and mass. Same speed and more mass means the truck wins.</span>
Answer:
Explanation:
a )
Zn = Zn²⁺ + 2e ( oxidation reaction )
Fe³⁺ + 3e = Fe( s ) ( reduction reaction )
b )
[ Zn = Zn²⁺ + 2e ] x 3
[ Fe³⁺ + 3e = Fe( s ) ] x 2
-------------------------------------------------------------------
3 Zn + 2 Fe³⁺ + 6e = 3 Zn²⁺ + 2 Fe ( s ) + 6e
3 Zn + 2 Fe³⁺ = 3 Zn²⁺ + 2 Fe ( s )
Answer:
5 cc
Explanation:
.01 M * 500/1000 = .005 M needed
1.0 M * x .005 M
x =.005 liter 5 cc
5cc of 1M dilute to 500 cc
Because the triangles are similar, their angles will be equivalent.
mO = 180 - 44 - 66
mO = 70°
