What is the molecular weight of the gaseous form of hcl?

a.) 357.413 amu
b.) 34.44506 amu
c.) 19.9062 amu
d.) 36.46094 amu

The answer is D because the mass of H is 1.008 and the mass of Cl is 35.45. When added up the answer is around 36.458. Depending on your periodic table and number of significant figures the values would be different slightly. 36.458 is pretty close to 36.46094 compared to other answers. Hope this helps!

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 

Iwould think it would be efficiency.
