a covalent bond should be present between substances when the difference in their electronegativities is less than around 1.7. however this is a rough guide, as there is no real distinction between covalent and ionic bonds, there are really just increasingly polar covalent bonds. or for a more gcse-level answer, you can expect that covalent bonds should be formed when non-metals react with other non-metals.
The systematic name of this compound is Oxygen(II) Fluoride. N.B. This compound is a fluoride of oxygen. It should not be mistaken as a oxide of fluorine.
Yes, the relative positions of carbon, hydrogen, and oxygen in the periodic table agree with the theoretical prediction about the kind of compound they should form. Carbon and oxygen are in the same group and tend to form covalent compounds, while hydrogen typically forms compounds with other elements through ionic or covalent bonds. Sucrose, a compound made of carbon, hydrogen, and oxygen, is a covalent compound in line with these predictions.
False, all compounds are electrically neutral.
Mass?Here it is with an example.. a compound of 78.14% Boron and 21.86% hydrogen with an experimental mass of 27 to 28 g. The empirical formula is as above BH3and Molecular formula is B2H6Molar mass / by empirical formula mass should give you an integer to multiply the empirical formula (BH3) with. This time it was 2 (rounded).
As a general rule, the further apart elements are on the periodic table, the more likely the compound that they form is ionic. Consequentlly, the closer they are, the more likely they will be covalent. If you have the electronegativity values for the elements in question, you can calculate whether the compound is covalent, polar covalent, or ionic. Find the absolute valule of the difference between the electronegativities of the elements. If the difference is: 0 to .5 = covalent .5 to 1.9 = polar covalent 1.9 to infinity = ionic
When all reactants are non-metals
The systematic name of this compound is Oxygen(II) Fluoride. N.B. This compound is a fluoride of oxygen. It should not be mistaken as a oxide of fluorine.
No, cyclohexane is a cycloalkane and not an aromatic compound. Aromatic compounds have a specific type of stability due to resonance in their pi electron system, while cyclohexane does not possess this type of stability.

Organic compounds should contain Carbon.So it is not organic.
False, all compounds are electrically neutral.
No, this molecule is not ionic. It is composed of all non metal atoms. In order to be ionic, the compound should consist of the following combinations: metal + nonmetal, or metal + polyatomic ion, or 2 polyatomic ions together.
Yes, except that "element" should be pluralized; a compound always has at least two elements.
Assuming you mean "contain" in a physical sense (because chemically speaking, no element can "contain" a compound) ... Sulfur should work. Carbon ought to work as well.
