If a dog has a mass of 24.9 kg, what is its mass in the following units?

please mark brainiliest pleas

Explanation:

i think if the following unit is grams the mass will be

1kg = 1000g

24.9kg = (1000 × 24.9)g

= 24900g that is the mass

8 carbon atoms forming single bonds with 18 hydrogen atoms; a triple bond exists between the third and fourth carbon atom from the right

explanation:

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
