Calcium chloride and baking soda solution: ... If you add them to vinegar they both form bubbles in a chemical reaction, but the ... How can chemical reactions help you tell the difference between similar of a gas, change in temperature, color change, or formation of a precipitate, ...

It turns into a gas and after the gas has left the chemical change is that the vinegar and baking soda will become a carbon dioxide 

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
