Use the mole-mole ratio to solve it/

1.2 mol FeO (2 mol Al/ 3 mol FeO)= 0.80 mole FeO

Stoichiometry. Are my answers right?

OverLord2011 [107]

Answer:

Congratulations. Mostly correct.

Step-by-step explanation:

Part I. Gold

Moles of Au = 35.12 2g × 1/196.97 = 0.1783 mol Au

Atoms of Au = 0.1783 × 6.022 × 10²³/1 = 1.074 × 10²³ atoms Au

Part II. Sucrose

Molar mass = 342.30 g/mol

Moles of C₁₂H₂₂O₁₁ = 1.202 g × 1/342.30

Moles of C₁₂H₂₂O₁₁ = 0.003 512 mol C₁₂H₂₂O₁₁

Moles of C = 0.003 512 × 12/1 = 0.042 14 mol C

Moles of H = 0.003 512 × 22/1 = 0.077 25 mol H

Moles of O = 0.003 512 × 11/1 = 0.038 63 mol O

Atoms of C = 0.042 14 × 6.022 × 10²³ = 2.538 × 10²² atoms C

Atoms of H = 0.077 25 × 6.022 × 10²³ = 4.652 × 10²² atoms H

Atoms of O = 0.038 63 × 6.022 × 10²³ = 2.326 × 10²² atoms O

<em>Minor Quibbles: </em>

You put the moles of sucrose in the molar mass slot.

You got the wrong exponents for the atoms of C, H, O.

You followed the rules for significant figures for gold, but not for sucrose.

Indicate whether each statement is true or false. Sort these statements into the proper categories.

tankabanditka [31]

Answer:

Answer below

Explanation:

A - false

B - true

C - false

In chemistry there is a principle that polar compounds are soluble with other polar compounds and non-polar compounds are mutually different.

Thus, sodium chloride is an ionic salt (polar) so it is not soluble in the benzene (non-polar) covalent compound, but it is soluble in water that is polar.

The ionic compounds will be soluble in polar solvents and not soluble in non-polar solvents, regardless of whether they are organic or inorganic.

if the complex has a formula of [m(h2o)6]3 , what effect will replacing the 6 aqua ligands with 6 cl− ligands have on δ ?

Eduardwww [97]

When we replace neutral ligands with negative ligands then the value of C.Δ will decrease.

In coordination chemistry, a ligand is an ion or molecule that binds to a significant steel atom to shape coordination complicated. The bonding with the metal generally includes a formal donation of 1 or more of the ligand's electron pairs regularly through Lewis Bases.

A ligand is defined as any molecule or atom that irreversibly binds to a receiving protein molecule, otherwise known as a receptor. whilst a ligand binds to its respective receptor, the shape and/or interest of the ligand is altered to provoke several special styles of cellular responses.

MULTIPLE CHOICE<br> What is the molality (m) of 3.5 mol of sugar in 2.5 kg of water?

otez555 [7]

The molality of the solution is 1.4 moles per kilogram (molal).

The molality of the solution is equal to the number of moles of sugar (solute) divided by the number of kilograms of water (solvent). Hence, the molality is determined below:

$m = \frac{3.5\,mol}{2.5\,kg}$

$m = 1.4\,\frac{mol}{kg}$

The molality of the solution is 1.4 moles per kilogram (molal).
