Answer:
FIREWORKS : WHEN FIREWORKS EXPLODE THEY EXPEL SMOKE WHICH IS A FORM OF GAS AND THEY LIGHT UP WHICH IS ANOTHER CHEMICAL REACTION AND OF COURSE THE WHOLE FIREWORK GETS HOT ( Temperature rises )
Explanation:
you could see your reaction happens when original substance changes in color temperature formation produces light or gas in many other things
( besides it's original form! )
answer what changed from it's original form!
ex: baking a cake:
the cake change form ( rising ) due to heat ( rising temperature )
REACTION WAS:
- formation of precipitate ( solid to settle out of a solution )
- change I'm temperature to bake the cake
Extra:
you got this!
I hope I helped even just a little!
Answer:
Melting
Explanation:
When you melt a sedimentary rock it becomes magma. Once that magma cools and hardens it becomes an igneous rock.
Answer:
CO.
Explanation:
Assuming the given percentages are by mass, we can solve this problem via imagining we have <em>100 g of the compound</em>, if that were the case we would have:
Now we <u>convert those masses into moles</u>, using the<em> elements' respective molar masses</em>:
- 42.9 g of C ÷ 12 g/mol = 3.57 mol C
- 57.1 g of O ÷ 16 g/mol = 3.58 mol O
As the number of C moles and O moles is roughly the same, the empirical formula for the compound is <em>CO</em>.
Answer:
Explanation: The key difference between Complete ionic and net ionic equation is that complete ionic equation gives all the ionic species participated in the chemical reaction whereas net ionic reaction gives the chemical species participated in the formation of the final product.
