When carbon is burned in air, it reacts with oxygen to form carbon dioxide. when 15.6 g of carbon were burned in the presence of 59.1 g of oxygen, 17.5 g of oxygen remained unreacted. what mass of carbon dioxide was produced?

5.72 g mass of carbon dioxide was produced

Explanation:

Moles of C =

Mass of reacted = 59.1 g - 17.5 g = 41.6 g

Moles of

According to reaction 1 mole produces 1 mole of then 1.3 mole of will produce moles of

Mass of :

=Moles of × molar mass of = 1.3 ×44 g/mol =

=57.2 grams

5.72 g mass of carbon dioxide was produced

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.
