Why do the two elements silver and iron have different properties?
Firdavs [7]
Elements in same group / family tend to have similar properties ( but not exactly the same). Since, iron and silver are in two different group / families, they have different properties.

Also, Silver and iron have different properties because they have different atomic structure. Having different atomic structure means bonding differently with other elements. So, they have different properties.

How many chloride ions are in a 220 grams of calcium chloride?
steposvetlana [31]

Answer: Hello, There! Your Answer is Below

2.4 x 1024 ions

Explanation:

220 g of CaCl₂  =  X moles

Solving for X,

                                                X  =  (220 g × 1 mol) ÷ 110.98 g

                                                X  =  1.98 moles

As,

                          1 mole contained  =  1.20 × 10²⁴ Cl⁻ Ions

Then,

                   1.98 mole will contain  =  X Cl⁻ Ions

Solving for X,

                                                 X  =  (1.98 mol × 1.20 × 10²⁴ Ions) ÷ 1mol

                                                 X  =  2.38 × 10²⁴ Cl⁻ Ions

Hope this Helps!

Have a great DAy!

The density of the hydrocarbon in part (a) is 2.0 g l-1 at 50°c and 0.948atm. (i) calculate the molar mass of the hydrocarbon. (
Vedmedyk [2.9K]

1. Answer;

=56 g/mol

Explanation and solution;

PV = nRT

nRT= mass/molar mass (RT)

molar mass = (mass/V ) × (RT/P)

                   = Density × (RT/P)

Molar mass = 2.0 g/L × (0.0821 × 323 K)/0.948 atm

Molar mass = 56 g/mol


2. Answer;

Molecular mass is C4H8

Explanation;

Empirical mass × n = molar mass

Empirical mass for CH2 = 14 g/mol

Therefore;

56 g/mol = 14 g/mol × n

   n = 4

The molecular formula= 4(CH2)

    = C4H8
