Answer 2

Answer:

Combinationreaction:−

✨In a combination reaction, two or more reactants add up to form a product.

EXAMPLES:EXAMPLES:

⭐The\:burning\:of\:carbon-Theburningofcarbon−

✨If we burn some charcoal (carbon) in a deflagrating spoon, and put the spoon in the mouth of an open gas jar and close the mouth of the jar with a lid and invert it, the limewater rises in the jar and becomes milky. This proves that carbon dioxide has been formed as it is a property of their gas to turn limewater milky.

So, during buring, carbon combined with the oxygen of the air to form carbon dioxide.

C+O2=>CO2C+O2=>CO2

⭐The\:burning\:of\:magnesium-Theburningofmagnesium−

✨ Magnesium is a silvery white metal.When it is ignited in the open air, it burns with dazzling white flame. Magnesium oxide, the product, deposits as a white smoky solid on the walls of the jar. Magnesium combines with the oxygen of the air during burning to form the product.

2Mg+O2=>2MgO2Mg+O2=>2MgO
