Explanation:

Carbon, Oxygen, Hydrogen

Reactants are carbon dioxide and water, products are glucose and oxygen

Dynamic Equilibrium I have no idea about (soz)

I believe this might be endothermic

Ionization energy increases as you move left to right in a period . that's why noble gases have high ionization energies.
shielding effect increases from top to bottom in a group atomic size also increases from top to bottom in a group

How many moles are present 560.0 g of iron (lll) sulfate

xxMikexx [17]

Answer:

1.400 mol

Explanation:

To convert grams to moles, you will need the molar mass. The molar mass of iron(iii) sulfate is 399.88 g/mol. Divide grams by the molar mass to find moles.

(560.0 g)/(399.88 g/mol) = 1.400 mol

There are 1.400 mol present in 560.0 g of iron(iii) sulfate.

What masses of sodium chloride, magnesium chloride, sodium sulfate, calcium chloride, potassium chloride, and sodium bicarbonate

andreyandreev [35.5K]

Answer:

NaCl: 184g

MgCl₂: 6.60g

Na₂SO₄: 9.26g

CaCl₂: 1.28g

KCl: 0.70g

NaHCO₃: 0.13g

Explanation:

To convert these concentrations to masses we need to convert molarity to moles and moles to grams using molar mass of each salt:

[CaCl₂] = [Ca²⁺] = 0.0115M

[HCO₃⁻] = [NaHCO₃] = 0.0015M

[SO₄²⁻] = [Na₂SO₄] = 0.0652M

[Mg²⁺] = [MgCl₂] = 0.0693M

[K⁺] = [KCl] = 0.0094M

And using the concentration of Cl⁻:

[Cl⁻] = [NaCl] + 2[MgCl₂] + 2[CaCl₂] + [KCl]

[3.32] = [NaCl] + 2[0.0693] + 2[0.0115] + [0.0094]

[NaCl] = 3.149M

The masses you need are:

<em>NaCl (Molar mass: 58.44g/mol):</em>

3.149mol/L * 1L * (58.44g/mol) =

<em>MgCl₂ (Molar mass: 95.211g/mol):</em>

0.0693mol/L * 1L * (95.211g/mol) =

Na₂SO₄<em> (Molar mass: 142.04g/mol):</em>

0.0652mol/L * 1L * (142.04g/mol) =

CaCl₂<em> (Molar mass: 110.98g/mol):</em>

0.0115mol/L * 1L * (110.98g/mol) =

KCl<em> (Molar mass: 74.55g/mol):</em>

0.0094mol/L * 1L * (74.55g/mol) =

<em>NaHCO₃ (Molar mass: 84g/mol):</em>

0.0015mol/L * 1L * (84g/mol) =

<h3>0.13g NaHCO₃</h3>
