Which Salt is least soluble at 50 C

Physics
1 answer:
Anvisha [2.4K]3 years ago
4 0

The salt c e_{2}\left(s o_{4}\right)_{3} is the least soluble salt at 50^{\circ} \mathrm{C}.

Answer: Option 1

<u>Explanation: </u>

As it is clear that c e_{2}\left(s o_{4}\right)_{3}, a gas so the solubility of it decreases on increasing the temperature of water. Because gas molecule starts to evaporate on attaining heat with the increase of temperature thus leading to reduction in the solubility of them.

As most of the gas molecules get vaporised the solubility in water gradually decreases for this compound. It is also clear from the solubility graphs of the various salts.

No, wearing sunscreen won't let you tan. The whole purpose of sunscreen is to protect your skin from sun rays. You can start to become tan if you dont have much sunscreen on - its happened to me.

9) What will happen to the period of a pendulum if we change the rope of a pendulum with another which is four times with the in
Arturiano [62]

Double

Explanation:

Since the period T of a pendulum is given by

T = 2\pi \sqrt{\dfrac{l}{g}}

By increasing the length of the pendulum by 4, the period becomes

T' = 2\pi \sqrt{\dfrac{4l}{g}} = 2\left(2\pi \sqrt{\dfrac{l}{g}}\right) = 2T

You can see that the period doubles when we increase the length by a factor of 4.

) determine the density of a 32.5 g metal sample that displaces 8.39 ml of water.
sweet-ann [11.9K]
Density is the ratio of a substance's mass to its volume. On the other hand, according to Archimedes' principle, the volume of water displaced is equal to the volume of the object placed on the water. Thus, the density of the metal is equal to 8.39 mL. So, the density would be

Density = 32.5 g/8.39 mL = 3.87 g/mL

The acceleration of a train moving from rest and its speed reaches 36m/sec in 9 sec​
jenyasd209 [6]

Answer:

4 m/s^2

Explanation:

The acceleration is defined as: Δv/Δt (the difference of the velocity over a time period in which happens that difference).

Remember that a difference is calculated by subtracting the initial value of a physical quantity from its final value.

In our case:

Δv = Vfinal - Vinitial = 36m/s - 0 m/s = 36m/s

Δt = 9s

a = Δv/Δt = 36m/s / 9s = 4m/s^2
