Why would it probably be very difficult to determine the chemical and physical properties of a newly discovered synthetic elemen
Alex17521 [72]
With newly discovered materials, nothing is yet know about them. Scientists don't know how to conduct physical/chemical experiments without damaging the element. Lethal substances or corrosive materials can be set off from combustion or decomposition. It would be difficult to determine the properties because no one knows what the element is made of. Chemical properties are often characterized by <span>reactivity with other chemicals, such as toxicity, coordination number, flammability, enthalpy of formation, the heat of combustion, and <span>oxidation states. It is difficult to measure those things when you have no idea what an element may be giving off. </span></span>

Why could element 119 be right below Fr in the periodic table if discovered?
faust18 [17]

Answer:

Ununennium, also known as eka-francium or element 119, is the hypothetical chemical element with symbol Uue and atomic number 119. Ununennium and Uue are the temporary systematic IUPAC name and symbol respectively, which are used until the element is discovered, confirmed, and a permanent name is decided upon. In the periodic table of the elements, it is expected to be an s-block element, an alkali metal, and the first element in the eighth period. It is the lightest element that has not yet been synthesized.

10. A compound has an empirical formula of CH, and a molecular mass of 6 points
Bogdan [553]

Answer:

Molecular formula = C₅H₁₀

Explanation:

From the question given above, the following data were obtained:

Empirical formula of compound => CH₂

Molar mass of compound = 70.1 amu

Molecular formula of compound =...?

The molecular formula of a compound is usually a multiple (n) of the empirical formula i.e

Molecular formula = [CH₂]ₙ

Thus, to obtain the molecular formula of the compound, we must first determine the value of n. The value of n can be obtained as follow:

[CH₂]ₙ = 70.1

[12 + (2×1)]n = 70.1

[12 + 2]n = 70.1

14n = 70.1

Divide both side by 14

n = 70.1 / 14

n = 5

Molecular formula = [CH₂]ₙ

Molecular formula = [CH₂]₅

Molecular formula = C₅H₁₀

Thus, the Molecular formula of the compound is C₅H₁₀.

Which chemical formula corresponds to this structural formula? c6h6h6h2 c14h6 c6h12 c6h14
Alexxandr [17]

The chemical formula C₂H₆O, which is designated as option D, is equivalent to this structural formula.

<h3><u>What is a Chemical Formula ?</u></h3>

Chemical element symbols, numbers, and occasionally additional symbols like parentheses, dashes, brackets, commas, and plus (+) and minus () signs are used in a chemical formula to represent information about the chemical proportions of the atoms that make up a certain chemical compound or molecule.

  • An empirical formula represents by symbols, such as Na for sodium and Cl for chlorine, with subscripts that show the relative number of atoms in each.
  • The composition of any member of an entire class of compounds can be represented by a general formula, a sort of empirical formula.
