Answer: The empirical formula for the given compound is
Explanation:
Mass of Sn = 11.775 g
Mass of O = 3.180 g
To formulate the empirical formula, we need to follow some steps:
Step 1: Converting the given masses into moles.
Moles of Sn =
Moles of O =
Step 2: Calculating the mole ratio of the given elements.
For the mole ratio, we divide each value of the moles by the smallest number of moles calculated which is 0.0992 moles.
For Sn =
For O =
Step 3: Taking the mole ratio as their subscripts.
The ratio of Sn : O = 1 : 2
Hence, the empirical formula for the given compound is

The major innovation made from Abacus to the present fifth generation is explained below in details.

Industrial Age - 1600
John Napier, a Scottish noble and diplomat consecrated much of his holiday time to the learning of mathematics. He was particularly engrossed in devising methods to aid estimates. His most famous offering was the discovery of logarithms. He listed logarithmic measures on a set of 10 board rods and thus was capable to do multiplication and division by equaling up numbers on the poles. These became recognized as Napier’s Bones.
Answer:
The correct answer is:Oxygen is more electronegative than carbon. See the explanation below, please
Explanation:
The electronegativities of oxygen and carbon are: 3, 44 and 2, 55 respectively. The electronegativity is defined as the capacity that a given atom has for the attraction of electrons, by forming a chemical bond. Polarity is related to electronegativity. The greater the difference in electronegativities between two atoms, the polarity of the bond they form will be greater.

<em>The following table illustrates some of the factors that influence the strength of intermolecular attractions. The formula of each entry is followed by its formula weight in parentheses and the boiling point in degrees Celsius. First there is molecular size. Large molecules have more electrons and nuclei that create van der Waals attractive forces, so their compounds usually have higher boiling points than similar compounds made up of smaller molecules. It is very important to apply this rule only to like compounds. </em><em>(Hope this helps!)</em>
