with. It reacts with bases, various metals, and strong oxidizing agents. Its vapors can form explosive mixtures with air.
Based on this information, which statement is applicable to glacial acetic acid?
It should be heated to remove moisture and stored on a lab shelf.
It should be handled on a clean, dry area of the lab bench.
It should be stored in an iron container, away from open flames.

Answer:

It should be handled in a fume hood, away from open flames.

Explanation:

The vapors can form explosive mixtures with air, so it should only be handled in a fume hood.  It should not be stored in an iron container because it reacts with metal.

Suppose that a spring with a larger spring constant was used in this same apparatus. If a given mass were rotated at the same ra
malfutka [58]

Answer:

The new period of rotation using the new spring would be less than the period of rotation using the original spring

Explanation:

Generally the  period of rotation of the mass is mathematically represented as

       T = 2 \pi \sqrt{\frac{I}{k} }

Here I is the moment of inertia of the mass about the rotation axis and  k is the spring constant

Now looking at the equation we can tell that T is inversely proportional to the square root of the spring constant which means that for a larger spring constant the time period would be lesser

The figure below shows two forces A=15 N and B=5 N acting on an object. What is the
alexandr1967 [171]

Answer:

18.03 N

Explanation:

From the fiqure below,

Using parallelogram law of vector

R² = 15²+5²-2×5×15cos(180-60)

R² = 225+25-150cos120°

R² = 250-150(-0.5)

R² = 250+75

R² = 325

R = √325

R = 18.03 N

Hence the resultant force of the object is 18.03 N
