Which statement is true about molecule speed? (1 point)
ANTONII [103]

Faster molecules have fewer collisions than slower molecules is True about molecular speed.

<h3>What is Molecular speed?</h3>

Molecular speed refers to the average distance gases or molecules travelled atca particular time rate.

It is valid in ideal gas, where the molecules do not interact with others.

Average molecular speed = Square root (3 (ideal gas constant) * (Temperature)/m)

Therefore, Faster molecules have fewer collisions than slower molecules is True about molecular speed.

Learn more about molecular speed from the link below.

Explain why the amino group of p-aminobenzoic acid does not participate in the reaction
lubasha [3.4K]

This is because amino group of p-aminobenzoic acid is an aniline and is less electrophilic than an alkyl amine.

<h3>What is an Aniline?</h3>

This is an aromatic amine which consists of a phenyl group attached to an amino group.

The amino group of p-aminobenzoic acid being an aniline makes it less electrophilic which is why an alkyl amine participates in the reaction instead.

Answer in explanation

Explanation:

A. This is wrong. The reactants are on the left side of the yields arrow

B. This is wrong. They can only be at one side at a time. They cannot be on both sides at the same time.

C. The products are on the right side of the yields arrow and not at the left side

D. This is correct. The reactants are on the left side of the yields arrow.

E. This is correct. We can have varying numbers of the number of atoms on both side of the yields arrow. The numbers may differ until we decide to balance the equation

What geologic processes are happening in the Lassen Volcanic National Park? Is it still being built up or taken away?
JulsSmile [24]

In May 1915, Lassen Peak, California, the southernmost active volcano in the Cascade Range, erupted explosively. Avalanches, mudflows, and flows of hot ash and gas devastated nearby areas, and volcanic ash fell as far away as 200 miles to the east. The Lassen area remains volcanically active, and the volcano hazards demonstrated in 1915 still can threaten not only nearby areas but also more distant communities. Recent work by scientists with the U.S. Geological Survey (USGS) in cooperation with the National Park Service is shedding new light on these hazards.


hope this helps!
