Na + Cl2 --&gt; NaCl if you were given 15 grams of sodium (with excess chlorine) and asked to determine the amount of NaCl that
Elena-2011 [213]

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

Explanation:

The female reproductive system is made up of structures, listed above, which functions together with the purpose of reproducing offsprings. Below is the structure matched with the correct function from the question given:

--> Egg: This functions as the sex cell or gamete

--> ovary: The site where gamete are produced

--> Fallopian tube: This functions to transport the gamete from the site of production in the reproductive system

--> Vagina: connects the internal reproductive fluids to the exterior.

The male reproductive system are also made up of structures that functions together to bring about the fertilization of the female sex cell. Below is the structure matched with the correct function from the question given:

--> Urethra: connects the internal reproductive fluids to the exterior.

--> Sperm:This functions as the sex cell or gamete

--> Testis: The site where gamete are produced

--> Vas deferens: This functions to transport the gamete from the site of production in the reproductive system.
