The formation of bubbles, a change in color, and the formation of a precipitate (1, 3, & 5) are all indicators that a chemical reaction is occurring.
Answer:
Explanation:
Applying conservation of momentum
mA v0 + 0 = mA x 12v0 + mB x 92v0
11 mA = - 92mB .
mA / mB = 92 / 11
mA : mB = 92 : 11.
Momentum = (mass) x (speed) .
So 907,175 kg-m/s = (36,287 kg) x (speed)
Divide each side by (36,287 kg):
Speed = (907,175 kg-m/s) / (36,287 kg)
<em>Speed = 25 m/s</em>
That's the truck's <em>speed</em>. We can't do anything that involves the truck's <em>velocity,</em> because we don't know what direction the truck is moving.
