Na+CL2=2NACL is the balanced reaction for the formation of table salt. Given 20 grams of Na and 10 grams of Cl2, which reactant
Elina [12.6K]

Excess reactant : Na

NaCl produced : = 16.497 g

<h3>Further explanation</h3>

Given

Reaction(balanced)

2Na + Cl₂⇒ 2NaCl

20 g Na

10 g Cl₂

Required

Excess reactant

NaCl produced

Solution

mol Na(Ar = 23 g/mol) :

= 20 : 23 = 0.87

mol Cl₂(MW=71 g/mol):

= 10 : 71 g/mol = 0.141

mol : coefficient :

Na = 0.87 : 2 = 0.435

Cl₂ = 0.141 : 1 = 0.141

Limiting reactant : Cl₂(smaller ratio)

Excess reactant : Na

Mol NaCl based on mol Cl₂, so mol NaCl :

= 2/1 x mol Cl₂

= 2/1 x 0.141

= 0.282

Mass NaCl :

= 0.282 x 58.5 g/mol

= 16.497 g

Hi I like a guy (He knows I like him too cause my friend told him) but me and this guy are really good friends how do I deal wit
kirza4 [7]

Answer:

Explanation:

When you start to feel you are desiring more than just a casual friendship with your best friend and you’re not sure what to do next, let me offer you some advice that could strengthen both your relationship and your love for each other.

First, don’t rush into a romantic relationship with your best friend…many times people confuse love with that other kind of caring love you feel for all of your other friends.

Second, don’t spill your guts right away. You might feel like you have to share all your thoughts and feelings with the other person as soon as you start to feel something. That’s usually a mistake.
