Answer:

The correct answer is - 38.15 gm of NaCl.

Explanation:

Write the balanced equation for this reaction of sodium (Na) and chlorine (Cl₂) to produce sodium chloride (NaCl):

2Na + Cl₂ —> 2NaCl

the mass of Na and the mass of NaCl :

Molar mass of Na = 23 g/mol

In the balanced equation = 2 × 23 = 46 g

Molar mass of NaCl = 23 + 35.5

= 58.5 g/mol

similarly in balanced equation = 2 × 58.5 = 117 g

From the balanced equation above,

46 g of Na reacted to produce 117 g of NaCl.

By converting it to 15 grams of Na.

Therefore,15 g of Na will react to produce = (15 × 117)/46 = 38.15 g of NaCl.

Thus, 38.15 g of Na

Do ecosystems change over time? Why or why not?
strojnjashka [21]
Ecosystems, the interactive system of living and nonliving organisms in a specific location, CHANGE SLOWLY OVER TIME. When new plants and animals arrive in an area, they either thrive or struggle. Thriving species sometimes displace native species. When this happens, the system as a whole begins to change.
