Imagine that you combine lemon juice with baking soda in a glass. you see gas bubbles forming along the sides of the glass. how are the chemical properties of the gas different from the chemical properties of the baking soda and lemon juice?

Gas released in this process is a totally different chemical substance in comparison to the baking soda and lemon juice. It should be Carbon Dioxide formed during the reaction.

Explanation:

We have a baking soda in a glass: it is composed of water and baking soda (NaHCO3). We have lemon juice, its main component is the citric acid (H3C6H5O7). After that, both liquids are mixed and an acid-base reaction occurs.

The reaction releases gas, which should be carbon dioxide (CO2), according to this reaction:

H3C6H5O7 (aq) + 3 NaHCO3 (aq) → 3 CO2 (g) +3H2O (l) + Na3C6H5O7 (aq)

The products of this reaction are Water (H2O) a Salt and carbon dioxide. As carbon dioxide is in the gas phase, it will be released from the liquid mixture as bubbles.

Finally, we can conclude that Gas released in this process is a totally different chemical substance in comparison to the baking soda and lemon juice. It should be Carbon Dioxide formed during the reaction.  

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.
