In the following reaction, which substance is the precipitate?(NH4)2SO4(aq) + Ba(NO3)2(aq) BaSO4(s) + 2NH4NO3(aq

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.

Answer:

3) D: 31 m/s

4) D: 84.84 metres

Explanation:

3) Initial velocity along the x-axis is;

v_x = v_o•cos θ

Initial velocity along the y-axis is;

v_y = v_o•sin θ

Plugging in the relevant values, we have;

v_x = 31 cos 60

v_x = 31 × 0.5

v_x = 15.5 m/s

Similarly,

v_y = 31 sin 60

v_y = 31 × 0.8660

v_y = 26.85 m/s

Thus, magnitude of the initial velocity is;

v = √(15.5² + 26.85²)

v ≈ 31 m/s

4) Formula for horizontal range is;

R = (v² sin 2θ)/g

R = (31² × sin (2 × 60))/9.81

R = 84.84 m

The critical angle for a certain air-liquid surface is 47.7°. What is the index of refraction of the liquid? Round to the neares

KengaRu [80]

Answer:

The index of refraction of the liquid is 1.35.

Explanation:

It is given that,

Critical angle for a certain air-liquid surface, $\theta_1=47.7^{\circ}$

Let n₁ is the refractive index of liquid and n₂ is the refractive index of air, n₂ =1

Using Snell's law for air liquid interface as :

$n_1\ sin\theta_1=n_2\ sin(90)$

$n_1\ sin(47.7)=1$

$n_1=\dfrac{1}{sin(47.7)}$

$n_1=1.35$

So, the index of refraction of the liquid is 1.35. Hence, this is the required solution.

natima [27]

Answer:

Nature of Sound Waves Sound is a wave that is created by perturbations and propagated through a medium from one location to another. Type of Wave: longitudinal wave. A sound wave consists of a repeating pattern of high-pressure and low-pressure regions moving through a medium Sound needs a medium of propagation and a disturbance. Like any wave, the speed of a sound wave refers to how fast the disturbance is passed from particle to particle. Anatomy of a Wave:
