I have 3 questions that I am uncertain about.

1) what determines the order in which the coumponent elements of binary molecular compounds are written?
2) Name the Binary compound according to the prefix system for As2O5
3) write the formula for each of the binary compound for tetraphosphorus decoxide.

1. Usually the cation (more electropositive element) is named first followed by the anion (more electronegative element).

2. diarsenic pentoxide

3. P4O10
but I don't understand the EACH OF THE....There is only one compound here. Unless you want the equation.
P4 + 5O2 ==> P4O10

Sure, I can help you with your questions:

1) The order in which the component elements of binary molecular compounds are written is determined by their electronegativity values. The element with the lower electronegativity is written first, followed by the element with the higher electronegativity. Electronegativity is a measure of an atom's ability to attract electrons towards itself in a chemical bond.

2) To name a binary compound according to the prefix system, you need to determine the number of atoms of each element in the compound. In the case of As2O5, "As" represents arsenic and "O" represents oxygen. The prefix "di" is used for "2" in front of the first element, and the prefix "penta" is used for "5" in front of the second element. Therefore, the name of the compound As2O5 is diarsenic pentoxide.

3) To write the formula for the binary compound tetraphosphorus decoxide, you need to know the chemical symbols and valencies of the two elements involved. "Tetra" indicates "4" and "deco" indicates "10" as prefixes. The chemical symbol for phosphorus is "P" and its valency is 5. Therefore, the formula for tetraphosphorus decoxide is P4O10.

Remember, it is always essential to verify these answers using appropriate chemical references or consult a chemistry expert.

Certainly! I'll be happy to help you with your questions step-by-step.

1) The order in which the component elements of binary molecular compounds are written is determined by the electronegativity values of the elements. The element with the lower electronegativity value appears first, followed by the element with the higher electronegativity value.

2) To name the binary compound As2O5 using the prefix system, you first identify the elements in the compound. In this case, "As" represents arsenic and "O" represents oxygen. The prefix "di-" indicates two atoms of arsenic, and the prefix "penta-" indicates five atoms of oxygen. So, the name of the compound is "Diarsenic pentoxide."

3) To write the formula for the binary compound tetraphosphorus decoxide, you first identify the elements present in the compound. "Tetra-" indicates four atoms of phosphorus, and "de-" indicates ten atoms of oxygen. The formula for tetraphosphorus decoxide is P4O10.

I hope this helps! If you have any more questions, feel free to ask.
