Liquid silver is less dense than solid silver, so the solid silver would sink.
Helga [31]3 years ago
5 0

<u>Answer:</u> The solid silver will sink in liquid silver.

<u>Explanation:</u>

Density of an object is defined as the ratio of mass of the object and volume of the object. The chemical equation representing density of an object is:

\text{Density of an object}=\frac{\text{Mass of an object}}{\text{Volume of an object}}

In solid state, the particles are closely packed. So, the volume of solid state is less than liquid state. Thus, density of solid will be more than the density of liquid.

A substance having more density will sink at the bottom and the substance having less density will float at the top.

Solid silver has more density than liquid silver.

Hence, the solid silver will sink in liquid silver.

a solution of HCI contains 36 percent HCI,by mass and calculate the mole fraction of HCI in the solution?​
denis-greek [22]

Explanation:

You have a solution that contains 36 g HCl dissolved in 64 g water

Molar mass HCl = 36.45 g/mol

Mol HCl in 36 g = 36 g / 36.45 g/mol = 0.9876 mol

Molar mass H2O = 18 g/mol

Mol H2O in 64 g = 64 g / 18 g/mol = 3.5556 mol

Total mol = 0.9875 + 3.5556 = 4.5431 mol

Mol fraction HCl = 0.9876 mol / 4.5431 mol = 0.2174

Mol fraction H2O = 3.5556 / 4.5431 = 0.7826

The answer should have 2 significant digits:

Mol fraction HCl = 0.22

Mol fraction H2O = 0.78

Mol fraction has no units.

THAT IS HELPFUL FOR YOU

A student is asked to standardize a solution of barium hydroxide. He weighs out 0.978 g potassium hydrogen phthalate (KHC8H4O4,
Sav [38]

Answer:

(A) 0.129 M

(B) 0.237 M

Explanation:

(A) The reaction between potassium hydrogen phthalate and barium hydroxide is:

  • 2HA + Ba(OH)₂ → BaA₂ + 2H₂O

Where A⁻ is the respective anion of the monoprotic acid (KC₈H₄O₄⁻).

We <u>convert mass of phthalate to moles</u>, using its molar mass:

  • 0.978 g ÷ 156 g/mol = 9.27x10⁻³ mol = 9.27 mmol

Now we <u>convert mmol of HA to mmol of Ba(OH)₂</u>:

  • 9.27 mmol HA * \frac{1mmolBa(OH)_{2}}{2mmolHA} = 6.64 mmol Ba(OH)₂

Finally we calculate the molarity of the Ba(OH)₂ solution:

  • 6.64 mmol / 35.8 mL = 0.129 M

(B) The reaction between Ba(OH)₂ and HCl is:

  • 2HCl + Ba(OH)₂ → BaCl₂ + 2H₂O

So<u> the moles of HCl that reacted </u>are:

  • 17.1 mL * 0.129 M * \frac{2mmolHCl}{1mmolBa(OH)_2} = 4.41 mmol HCl

And the <u>molarity of the HCl solution is</u>:

  • 4.41 mmol / 18.6 mL = 0.237 M

How many grams of F2 are in 3.45 x 1022 molecules of F2?
Fofino [41]

Answer:

Mass = 2.16 g

Explanation:

Given data:

Number of molecules of F₂ = 3.45 × 10²²

Mass in gram = ?

Solution:

Avogadro number:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ molecules

3.45 × 10²² molecules ×1 mol / 6.022 × 10²³ molecules

0.57× 10⁻¹  mol

0.057 mol

Mass in gram :

Mass = number of moles × molar mass

Mass = 0.057 mol × 37.9 g/mol

Mass = 2.16 g
