Is this an experiment? If so, if you have a small environment, compare it to a larger one, like your backyard for instance. Does the small environment have the same things as your backyard? Are they different? Compare them both like the backyard would have trees and with bird nests, and bushes, and all sorts of living organisms. More than your small environment would right? Your small environment gets the same nutrients as the large environment such as Carbon Dioxide, Sunlight, Water. Does your small environment have any animals or insects? You could use that as a comparison too.

I Hope This Helped!

How many grams of O₂ are required to react completely with 14.6 g of Na to form sodium oxide, Na₂O?

Bad White [126]

The balanced chemical reaction is :

$O_2 + 4Na \ -> \ 2Na_2O$

Number of moles of Na, $n = \dfrac{14.6}{23} = 0.635 \ mol$ .

Now, from balance chemical reaction we can see that 1 mole of oxygen reacts with 4 moles of sodium.

So, number of moles of oxygen are :

$n = \dfrac{0.635}{4}\ mole$

So, amount of oxygen required is :

$m = \dfrac{0.635 \times 32}{4}\ gm\\\\m = 5.08 \ gm$

Therefore, 5.08 gram of oxygen will react with 14.6 gram of sodium.

Complete the equation for the reaction of NaHCO 3 ( s ) NaHCO3(s) with HC 2 H 3 O 2 ( aq ) HC2H3O2(aq) . Include phase symbols.

UNO [17]

Answer:

NaHCO 3 ( s ) + HC 2 H 3 O 2 ( aq ) ⟶NaHC2H3O2 + H2CO3 → H2O + CO2

NaHCO3 + HC2H3O2 → NaC2H3O2 + H2O + CO2

Explanation:

Sodium bicarbonate and acetic acid reacts to form Sodium acetate and carbonic acid. The carbonic acid then produce carbon dioxide gas and water after undergoing decomposition.
