Write the empirical formula of at least four binary ionic compounds that could be formed from the following ions: ,
Serga [27]
Bynari means that the compound is formed by two kind of elements.

You have listed three ions, V 5+, Cl - and O 2-.

Binary ionic compounds are formed by a positive ion and a negative ion, so the possible ionic compound formed by the listed ions are:

1) VCl5, where the number 5 next to Cl is a subscript.

2) V2O5, where the number 2 next to V and the number 5 next to O are subscripts.

Subscripts are used to indicate the number of atoms of each element in the formula.

So, the empirical formula searched are VCl5 and V2O5.

I can give you other examples with more ions.

Ca (2+) and S(2-) => Ca2S2 => CaS

Na(+) and F(-) => NaF

Cs(+) and Br(-) => CsBr

Which of the following statements are TRUE? Group of answer choices Dynamic equilibrium indicates that the amount of reactants a
White raven [17]

Answer:

Below answers are correct.

1) Dynamic equilibrium indicates that the amount of reactants and products are equal.

2) A reaction quotient (Q) larger than the equilibrium constant (K) means that the reaction will favor the production of more products.

3) Dynamic equilibrium occurs when the rate of the forward reaction equals the rate of the reverse reaction

Explanation: Dynamic equilibrium is also called reversible reaction because it moves both in farward as well as in backward direction. Dynamic equilibrium occurs when reactants convert into products and products convert into reactant at the same time. It only occurs when the reaction occurs in closed container.

Enter the chemical formula of a binary molecular compound of hydrogen and a Group 4A element that can reasonably be expected to
irakobra [83]

Answer: GeH4 (Germanium(IV) Hydride)

Explanation:

A Binary molecular compound Hydrogen and a Group 4A element which is more more acidic than SiH4 in aqueous solution is GeH4.

The pKa of GeH4;

= 25

Whilst that of SiH4

= 35

The lesser the pKa the higher the Ka which means more acidic.

What mass of sodium chloride contains 4.59 x 10 24 formula units?
shtirl [24]
The term formula units means molecules.

Then, what you are looking for is the mass in 4.59*10^24  molecules.

The procedure involves to convert the 4.59 * 10^24 molecules into moles and use the molar mass of the sodium chloride.

1) Number of moles = 4.59 * 10^24 molecules / (6.02 * 10^23 molecules/mol) = 7.62 mol

2) Molar mass of NaCl = 22.99 g/mol + 35.45 g/mol = 58.44 g/mol

3) mass of NaCl = molar mass *  number of moles = 58.44 g/mol * 7.62 mol = 445.31 g of NaCl

Answer: 445.31 g of NaCl.
