How does omitting triethanolamine affect the properties and appearance of the hand lotion?

2 answers:

<span>Omitting this substance will not affect the appearance of hand lotion because it is a white or off white color. Since it is an alcohol compound if it is left out of the formula it will keep your hands from drying out as fast. </span>Triethanolamine is considered as an amine alcohol. The compound itself does not affect much the appearance of the hand lotion prepared as it is colorless, But, the alcohol If avoided would result in a hand lotion which would not get dried out easily

SO2+O2 SO3 how many moles of O2 needed to combust 100.0g of sulfur dioxide

Oksanka [162]

2SO2 + O2 ------> 2SO3

1) M(SO2)= 32.0 + 2*16.0 = 64 g/mol

2) 100.0 g SO2 * 1 mol SO2/64 g SO2 = 1.5625 mol SO2

3) 2SO2 + O2 ------> 2SO3

2 mol 1 mol

1.5625 mol x mol

x= 1.5625/2=0.78125 ≈ 0.7813 mol O2

Answer: 0.7813 mol O2.

Calculate the volume in liters of a M magnesium fluoride solution that contains of magnesium fluoride . Round your answer to sig

AveGali [126]

The given question is incomplete. the complete question is:

Calculate the volume in liters of a 0.91 M magnesium fluoride solution that contains 249.2 g of magnesium fluoride . Round your answer to 2 significant digits.

Answer: 4.4 Liters

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

$Molarity=\frac{n}{V_s}$

where,

n = moles of solute

To calculate the moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}=\frac{249.2g}{62.3g/mol}=4.00moles$

$V_s$ =volume of solution in L

$0.91=\frac{4.00}{V_s}$

Thus the volume in liters is 4.4 L

This is the chemical formula for acetic acid (the chemical that gives the sharp taste to vinegar): an analytical chemist has det

zhannawk [14.2K]

<h3>Answer:</h3>

3.2 moles of Oxygen

<h3>Explanation:</h3>

Acetic Acid having chemical formula C₂H₄O₂ and structural formula attached below is the second member of carboxylic family in organic compounds. It is commonly used as vinegar<em> i.e</em>. a mixture containing 5 % Acetic acid and 95 % water.

As shown in structure 1 mole of Acetic acid contains 2 moles of Carbon atoms, 4 moles of Hydrogen atoms and 2 moles of Oxygen atoms respectively. Hence, the number of moles of Oxygen atoms contained by acetic acid containing 3.2 moles of Carbon is calculated as,

2 moles of C accompany = 2 moles of O

So,

3.2 moles of C will accompany = X moles of O

Solving for X,

X = (3.2 mol C × 2 mol O) ÷ 2 mol C

X = 3.2 mol of Oxygen

Give reason why wood is solid?

VARVARA [1.3K]

Solid wood is a term most commonly used to distinguish between ordinary lumber and engineered wood, but it also refers to structures that do not have hollow spaces. Engineered wood products are manufactured by binding together wood strands, fibers, or veneers with adhesives to form a composite material.

Woof. Hope it helps!!! :) ....Reason*
