What is the difference between a mineral and a rock
Sedbober [7]

A mineral is a naturally occurring, inorganic solid with a definite chemical composition and a crystalline structure formed by geological processes.

A rock is an aggregate of one or more minerals. It may also contain organic remains and mineraloids apart from regular mineral formations. Since rocks vary in their mineral and chemical composition, they are classified according to the process of their formation.

What is the frequency of a microwave of wavelength 3cm?
navik [9.2K]

Frequency = (speed) / (wavelength)

Speed = 3 x 10⁸ m/s

Wavelength = 3 cm = 0.03 m

Frequency = (3 x 10⁸  m/s) / (0.03 m)

Frequency = (3 x 10⁸ / 0.03) (m / m-s)

Frequency =  1 x 10¹⁰ Hz (10 Gigahertz)

A 7.99 g sample of hcn is found to contain 0.296 g of h and 4.14 g of n.Find the mass of carbon in a sample of hcn with a mass o
Thepotemich [5.8K]

<u>Answer:</u>

Mass of C in 3.40 g of HCN =1.51 gram.

<u>Explanation:</u>

  Mass of sample of HCN = 7.99 g

  Mass of H in 7.99 g of HCN = 0.296 g

  Mass of N in 7.99 g of HCN = 4.14 g

  Mass of C in 7.99 g of HCN = (7.99-0.296-4.14) = 3.554 g

  Now mass of HCN = 3.40 g

  Mass of C in 3.40 g of HCN = \frac{3.554}{7.99} *3.40 =1.51 g

 So mass of C in 3.40 g of HCN =1.51 gram.
