Chemistry

Answer:

It's only A

Explanation:

Potassium (K) is a metal and Chlorine (Cl) is a nonmetal, and ionic compounds are formed between metals and nonmetals. So KCl forms ionic bonds.

Hydrogen (H) and Chlorine (Cl) are both nonmetals, and only covalent bonds form between nonmetals. (Only exception is when its an acid, then it's ionic)

Also, the question indicated which "pair" and not "pairs" meaning that there is only one answer, and I'm more likely to go with A rather than D.

How would you convert 500cc of 2M H2so4 in g/l and normality?

Ann [662]

Concentration :

196 g/L and 4 N

<h3> </h3><h3>Further explanation</h3>

The concentration of a substance can be expressed in several quantities such as moles, percent (%) weight / volume,), molarity, molality, parts per million (ppm) or mole fraction. The concentration shows the amount of solute in a unit of the amount of solvent.

500 cc of 2M H₂SO₄

V = 500 cc = 0.5 L

mol H₂SO₄

$\tt mol=M\times V=2\times 0.5=1$

mass H₂SO₄ (MW = 98 g/mol)

$\tt mass=mol\times MW=1\times 98=98~g$

concentration in g/L :

$\tt \dfrac{98}{0.5}=196~g/L$

concentration in normality

Relationship between normality and molarity

N = M x n (n=valence , amount of H⁺ or OH⁻)

so :

$\tt N=2\times 2(n=2~for~H_2SO_4\rightarrow 2H^+)\\\\N=4$

How would you calculate the atomic mass of an atom of silver (Ag)?

iren [92.7K]

Answer:

107.8682 u

Explanation:

Well Silver has an atomic mass of aproximately 107.9. 1 mole of silver atoms = 107.9g and there are 6.02x10^23 atoms in one mole. Therefore to find mass of one atom you should divide the mass by Avodgadro's constant to find the mass of one atom because they all have an even distribution of mass.

The average atomic mass of the element takes the variations of the number of neutrons into account, and tells you the average mass per atom in a typical sample of that element. For example, the element silver (Ag) has two naturally occurring isotopes: Ag-107 and Ag-109 (or 107Ag and 109Ag).
