<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.

When a beam of charged particles moves through a magnetic field, what is the evidence that particles in the beam have momentum g
Vsevolod [243]

The charged particles are often deflated in a magnetic field.

<h3>What is a magnetic field?</h3>

The term charge refers to a positive or negative entity. The can be created when a charge is made to pass through a conductor in a magnetic field.

A magnetic field is created when we have a north pole and a south pole. The charged particles could be made to pass through the electric field and when that happens, we can see a pattern a shown in the image attached.

Thus, we can see that the charged particles are often deflated in a magnetic field.
