Magnesium metal reacts with hydrochloric acid to produce magnesium chloride and hydrogen gas; how can you prove that?

Thank you for the points

Explanation:

Explanation:

The magnesium reacts with the acid, producing visible bubbles of hydrogen gas. (Optional) If the flame of a butane fireplace lighter is held above the bursting bubbles, they will produce audible pops as the hydrogen ignites. Magnesium ribbon is a flammable solid. Hydrochloric acid is a corrosive liquid.

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.

i think its 100

i hope this !
