The solar system moves at the speed of 828,000 km/h. tara writes the following steps to calculate this speed in decameters/second (dm/s).
[1 km = 100 dm]
step 1: divide 828,000 by 100.
step 2: divide the result obtained in step 1 by 60.
step 3: divide the result obtained in step 2 by 60.
step 4: write the number obtained in step 3 with the unit dm/s.
which step is incorrect in the conversion? (1 point)
step 1
step 2
step 3
step 4

c- cold periods in earth's history during which glaciers covered much of the surface.

explanation:

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
