Fill in the coefficients that will balance the following reaction: a0nacl + a1cas → a2na2s + a3cacl2

Explanation: The coefficients of ,  ,  ,  and   are 2, 1, 1 and 1 respectively.

According to the law of conservation of mass, the mass of the products must be same as the mass of the reactants in every chemical equation.

In order to do so , the number of atoms of every element must be same on both sides of the equation and thus the chemical equation is balanced.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
