sweet-ann [11.9K]

Answer:

Synthesis or combination.

Explanation:

Hello there!

In this case, according to the given chart containing the types of reactions, it turns out possible for us infer this given reaction:

____ N2+__H2→ __NH3

Is synthesis or combination, because it follows the pattern A + B --> C. Moreover, it can be balanced as shown below:

N2+3H2→ 2NH3

Your teacher directs you to combine two liquid substances into a flask. after you combine them, you notice that the flask feels
adelina 88 [10]

Answer : The correct option is (A).

Explanation :

  • Endothermic reaction : When two liquids are combine into a flask, then the flask feels cold when we touch it because the system absorbed heat from the surrounding.

In general, endothermic process absorbs heat and cool the surrounding.

  • Exothermic reaction : When two liquids are combine into a flask, then the flask feels hot when we touch it because the system released heat into the surrounding.

In general, exothermic process releases heat and rise the temperature of surrounding.

Answer:

6. Double replacement "DR"

7. Double replacement "DR"

8. Combustion "C"

9. Single replacement "SR"

10. Decomposition "D"

Explanation:

- number 6 and 7 are double replacements because if you look at the compounds in the reactants vs the products, it is evident that there has been a replacement between Na & K in number 6 and Mg & Li in number 7, a "DR" occurs when the anions and cations in 2 molecules switch places to form 2 new compounds.

- number 8 is a combustion reaction because a combustion reaction occurs when oxygen is combined with another compound to form water and carbon dioxide (H2O & CO2).

- number 9 is a single replacement reaction because the Pb and Fe have simply switched places, "SR" are when an element trades with another to form a new compound and the element that was swapped.

- number 10 is a decomposition because it can be observed that the compound in the products is being broken down into the molecules or compounds that it is made up of, started with one and finished with 2
