Answer:

21000000 m/s

Explanation:

Data obtained from the question:

Speed of light = 300000000 m/s

Speed of Alpha Particle =.. ?

From the question given above, the speed of the alpha particle is 7% of speed of light. Since we know the value for the speed of light, therefore, we can obtain the value for the speed of the alpha particle as follow:

Speed of Alpha Particle = 7% x speed of light

Speed of Alpha Particle = 7/100 x 300000000

Speed of Alpha Particle = 21000000 m/s

A solid mixture consists of 47.6g of KNO3 (potassium nitrate) and 8.4g of K2SO4 (potassium sulfate). The mixture is added to 130

IgorLugansk [536]

<u>Answer:</u> No crystals of potassium sulfate will be seen at 0°C for the given amount.

<u>Explanation:</u>

We are given:

Mass of potassium nitrate = 47.6 g

Mass of potassium sulfate = 8.4 g

Mass of water = 130. g

Solubility of potassium sulfate in water at 0°C = 7.4 g/100 g

This means that 7.4 grams of potassium sulfate is soluble in 100 grams of water

Applying unitary method:

In 100 grams of water, the amount of potassium sulfate dissolved is 7.4 grams

So, in 130 grams of water, the amount of potassium sulfate dissolved will be $\frac{7.4}{100}\times 130=9.62g$

As, the soluble amount is greater than the given amount of potassium sulfate

This means that, all of potassium sulfate will be dissolved.

Hence, no crystals of potassium sulfate will be seen at 0°C for the given amount.
