This is a one-step unit analysis problem.  Since we are staying in moles, grams of our compound, and thus molar mass, is not needed.

1 mole is equal to 6.022x10²³ particles as given, so:

1.5x10^{24} particles FeO_{2} (\frac{1mol}{6.022x10^{23}particles } )=2.49 molFeO_{2}

<h3>Answer:</h3>

2.49 mol

If the value for ΔS is postive, and the value for ΔH is negative, thr reaction will be
dmitriy555 [2]

It follows that the reaction is spontaneous at high temperatures Option A.

<h3>What is ΔS ?</h3>

The term ΔS is referred to as the change in the entropy of the system. Now recall that entropy is defined as the degree of disorderliness in a system. If a system is highly disorderly then it means that it has a high entropy. Also, ΔH has to do with the heat change that accompanies a reaction.

We know that both the entropy and the heat change can both either be positive or negative. Now we know that the equation ΔG = ΔH - TΔS can be used to ascertain whether or not a reaction will be spontaneous. If the result is negative, then the reaction will be spontaneous.

As such, when then it follows that the reaction is spontaneous at high temperatures Option A.

In Lab 3, Solubility Rules, students identified ionic salts as soluble or insoluble. The solubility of ionic salts is quantified
Hatshy [7]

Answer:

a) FePO4(s)⇄Fe^3+(aq) + PO4^3-(aq)

b) ZnCO3(s)⇄Zn^2+(aq) + CO3^2-(aq)

c) NH4Cl(s)⇄ NH4^+(aq) + Cl^-(aq)

Explanation:

An ionic solid simply means a solid substance that is held together by ionic bonds. When an ionic substance is added to water, the ions interact with the dipoles in water and is pulled apart to form the constituent cation and anion present in the ionic solid. This is the process that we have referred to as dissolution.

The Ksp of an ionic solid is obtained from the chemical equation that shows the dissolution of an ionic solid in water. The Ksp is actually an equilibrium constant that shows the extent of dissolution of an ionic solid in water.

a) FePO4(s)⇄Fe^3+(aq) + PO4^3-(aq)

b) ZnCO3(s)⇄Zn^2+(aq) + CO3^2-(aq)

c) NH4Cl(s)⇄ NH4^+(aq) + Cl^-(aq)

If you want to determine the actual salicylate concentration for a sample that gives a greater absorption than the highest conce
Anarel [89]

Answer: The concentration of unknown sample is 1.8 mg/ml

Explanation:

According to the dilution law,

M_1V_1=M_2V_2

where,  

M_1 = concentration of stock solution = ?

V_1 = volume of stock solution = 0.25 ml  

M_1 = concentration of diluted solution = 0.45 mg/ml

V_1 = volume of diluted solution = (0.25+0.75) ml = 1.00 ml

Putting in the values we get:

M_1\times 0.25=0.45\times 1.00

M_1=1.8mg/ml

Therefore, concentration of unknown sample is 1.8 mg/ml
