Answer is: 588.15 <span>grams of ethanol.
</span>Chemical reaction: C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂.
m(C₆H₁₂O₆) = 1150 g.
n(C₆H₁₂O₆) = m(C₆H₁₂O₆) ÷ M(C₆H₁₂O₆).
n(C₆H₁₂O₆) = 1150 g ÷ 180.16 g/mol.
n(C₆H₁₂O₆) = 6.38 mol.
From chemical reaction: n(C₆H₁₂O₆) : n(C₂H₅OH) = 1 : 2.
n(C₂H₅OH) = 12.76 mol.
m(C₂H₅OH) = 12.76 mol · 46.07 g/mol.
m(C₂H₅OH) = 588.15 g.
The volume of the gold chain is 4.18 cm³
<h3>What is density? </h3>
The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as
Density = mass / volume
With the above formula, we can determine the volume of the chain. Details below:
<h3>How to determine the volume of the gold chain</h3>
The following data were obtained from the question:
- Mass of gold = 80.7 g
- Density of gold = 19.3 g/cm³
- Volume of gold chain =?
Density = mass /volume
Cross multiply
Density × volume = mass
Divide both sides by density
Volume = mass / density
Volume of gold chain = 80.7 / 19.3
Volume of gold chain = 4.18 cm³

C is wrong, the real answer is B: to add tartness, and the reason why is because citric acid comes from jam, jellies, and more! And that is why the answer B is the correct answer.
Hope this helped!
Nate
(P.S. if you buy jams and real the ingredients, it will say "citric acid." :))
Answer:
Since the force applied at both ends is acting in opposite directions, then the resultant force becomes negative.
= 35 - 25 = 10
