Answer:
Identify each equation as a composition reaction, a decomposition reaction, or neither.
Fe2O3 + 3 SO3 → Fe2(SO4)3
NaCl + AgNO3 → AgCl + NaNO3
(NH4)2Cr2O7 → Cr2O3 + 4 H2O + N2
Solution
In this equation, two substances combine to make a single substance. This is a composition reaction.
Two different substances react to make two new substances. This does not fit the definition of either a composition reaction or a decomposition reaction, so it is neither. In fact, you may recognize this as a double-replacement reaction.
A single substance reacts to make multiple substances. This is a decomposition reaction.

Answer:
B.
Explanation:
Velocity: the speed of something given direction
Acceleration: increase or decrease of velocity over time
B is the answer because it is the only point on the image that has to slow down and change direction. To turn, a vehicle must slow down so it doesn't skid. Hope this helps!
