<span>ammonium sulphate give 2 moles of ammonium ions
so conc. of ammonium ions =2*0.100=0.200 </span>
It would be a monopoly because in a monopoly good and services are provided by one producer and there is no competition. <span>

<span>Hey Jose! Thanks for asking a question here on Brainly.
⚪ Potassium
</span><span>⚪ Magnesium
</span><span>⚪ Sodium (aka Na)
</span><span>⚪ Lithium (aka Li)
These are all atoms that are likely to lose electrons in order to form cations. Hope this helps. -UF aka Nadia</span>
I would say 2)trade because every civilization will need to trade. You can’t find everything in one location.
The standard enthalpy of formation (Δ
) is a measure of the energy released or consumed when one mole of a substance is created under standard conditions from its pure elements.
Standard enthalpies (Δ) of formation for given reaction is 978.3 kJ
<h3>
What is Standard enthalpies of formation?</h3>
The standard enthalpy of formation is defined as the enthalpy change when one mole of a substance in the standard state (1 atm of pressure and 298.15 K) is formed from its pure elements under the same conditions.
Given reaction ;
To Find : Δ
Δ = ∑np Δ (products) – ∑np Δ (reactants)
Δ = [1(Δ 
) + 4(Δ 
)] – [1(Δ 
) + 4(Δ 
)]
Δ = [1(0) + 4(-241.8)] – [1(+9.16) + 4(0)]
Δ = [4(-241.8)] – [1(+9.16)] = 978.3 kJ
