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 is in excess? How much NaCL should be produced from these amounts of the two reactants?

Answers

Excess reactant : Na

NaCl produced : = 16.497 g

Further explanation

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

Compared to atoms of metals, atoms of nonmetals generally
A)have higher electronegativities
B)have lower first ionization energies
C)conduct electricity more readily
D)lose electrons more readily

Answers

The answer for the question is C

Compared to atoms of metals, atoms of nonmetals generally conduct electricity more readily. Therefore, option C is correct.

What are metal atoms ?

The term metal atom is defined as an atom of an element that exhibits typical metallic properties, being typically shiny, with high electrical and thermal conductivity.

Metallic bonds form when the charge is spread over a greater distance than the size of individual atoms in solids. Most left elements in the periodic table form metallic bonds, such as zinc and copper.

Metals are defined as elements to the left of the line. Elements just to the right of the line have both metal and nonmetal properties and are referred to as metalloids. Nonmetals are elements at the far right of the periodic table.

Thus, option C is correct.

What is the formula mass of NaCl?

Answers

Answer:

The molar mass of sodium is 22.990 g/mol.

The molar mass of chlorine is 35.45 g/mol.

To calculate the molar mass of NaCl, we need to multiply the subscript of each element times its molar mass, then add them together. In this case since there is no subscript, it is understood to be

( 1 × 22.990 g/mol ) + ( 1×35.45 g/mol ) = ?

22.990 g/mol + 35.45 g/mol = ?

58.44 g/mol = ?
