The precipitate is the barium sulfate, or 3) BaSO4. This is because it is a solid (as seen by the (s)), unlike the other aqueous product. The fact that it is a solid means that it is insoluble in water and therefore a precipitate.

Hope this helps!

Answer: Option (3) is the correct answer.

Explanation:

A precipitate is defined as an insoluble solid formed when two aqueous solutions chemically combine to each other.

For example, (NH_{4})_{2}SO_{4}(aq) + Ba(NO_{3})_{2}(aq) \rightarrow BaSO_{4}(s) + 2NH_{4}NO_{3}(aq)

Since, it is known that (aq) represents aqueous and (s) represents solid. So, in this reaction barium sulphate (BaSO_{4}) is the insoluble solid.

Hence, BaSO_{4} is the precipitate that is formed.

Thus, we can conclude that in the given reaction BaSO_{4} substance is the precipitate.

An ant crawls along a sidewalk with a velocity of 0.1 m/s in a direction that is 45 degrees relative to the edge of the sidewalk
ahrayia [7]

Answer:

C) 1.0 m

Explanation:

The component of the velocity parallel to the sidewalk is:

vₓ = v cos θ

vₓ = 0.1 m/s cos 45°

vₓ = 0.0707 m/s

The distance traveled after 14 seconds is:

d = vₓ t

d = (0.0707 m/s) (14 s)

d = 0.99 m

Closest answer is C) 1.0 m.

aniked [119]

Ike is at the beach watching the waves in the ocean. Ike notices that some of the waves are short. Other waves are very tall and come up high above the water. Two waves that are different heights because They have different amplitudes.

Answer: Option (D) is correct

Explanation:

The different heights of the waves are due to their different amplitudes. The Amplitude of a particular wave depends upon the amount of energy being carried by waves. It the waves carry more energy than their amplitude will be higher.

But if energy carried by a wave is less than the wave will have a low amplitude. The Amplitude shows the distance covered from the rest position to peak position.
