The empirical formula for this compound that contain 31.14%sulfur and 68.86%chlorine by mass
Kaylis [27]

The empirical formula is SCl_2.

The <em>empirical formula</em> (EF) is the simplest whole-number ratio of atoms in a compound.

The ratio of atoms is the same as the ratio of moles.

So, our job is to calculate the <em>molar ratio </em>of S to Cl.

Assume that you have 100 g of sample.

Then it contains 31.14 g S and 68.86 g Cl.

<em>Step</em> 1. Calculate the <em>moles of each element</em>

Moles of S = 31.14 g S × (1 mol S/(32.06 g S) = 0.971 30 mol S  

Moles of Cl = 68.86 g Cl × (1 mol Cl/35.45 g Cl) = 1.9425 mol Cl

<em>Step 2</em>. Calculate the <em>molar ratio</em> of each element

Divide each number by the smallest number of moles and round off to an integer

S:Cl = 0.971 30: 1.9425 = 1:1.9998 ≈ 1:2

<em>Step 3</em>: Write the <em>empirical formula</em>

EF = SCl_2

An aqueous solution of perchloric acid is standardized by titration with a 0.191 M solution of barium hydroxide. If 13.8 mL of b
WARRIOR [948]

Answer:

Molarity of HClO_{4} solution is 0.311 M

Explanation:

Neutralization reaction: 2HClO_{4}+Ba(OH)_{2}\rightarrow Ba(ClO_{4})_{2}+2H_{2}O

According to balanced reaction, 1 mol of Ba(OH)_{2} neutralizes 2 moles of HClO_{4}

Number of moles of Ba(OH)_{2} in 13.8 mL of 0.191 M Ba(OH)_{2} solution = \frac{0.191}{1000}\times 13.8moles = 0.00264moles

Let's assume molarity of HClO_{4} solution is C (M) then-

Number of moles of HClO_{4} in 17.0 mL of C (M) HClO_{4} solution = \frac{C}{1000}\times 17.0moles = 0.017Cmoles

Hence, 0.017C=(2\times 0.00264)

         or, C=0.311

So, molarity of HClO_{4} solution is 0.311 M

What is the job of these macromolecules ​
Ray Of Light [21]

Answer:

<u>When small organic molecules bind together, they form larger molecules called biological macromolecules.</u>Biological macromolecules are important cellular components and perform a wide array of functions necessary for the survival and growth of living organisms. The four major classes of biological macromolecules are carbohydrates, lipids, proteins, and nucleic acids.
