<u>Answer:</u> The balanced equation for the complete oxidation reaction of ethanol is
<u>Explanation:</u>
Combustion is the chemical process where an organic molecule reacts with oxygen gas present in the air to produce carbon dioxide and water molecules.
It is also known as an oxidation reaction because oxygen is getting added.
The chemical equation for the oxidation of ethanol follows:
By stoichiometry of the reaction:
1 mole of ethanol reacts with 3 moles of oxygen gas to produce 2 moles of carbon dioxide gas and 3 moles of water molecules.
Acids- Sulfuric acid, and hydrochloric acid
Base- Bleach, and ammonia
Neutral- Water
Answer:
A) It's correctly written
B) 77%
C) 835 calories
Explanation:
A) From online sources, we have number of calories as follows;
Fats: 9 calories per gram
Protein; 4 calories per gram
Carbs; 4 calories per gram
Total calories for each;
Total fat = 3 × 9 = 27 calories
Total protein = 3 × 4 = 12 calories
Total carbs = 32 × 4 = 128 calories
(sugar and dietary Fibre are classified as carbohydrates and so total carbs takes care of their calories).
Thus, total number of calories per serving = 27 + 12 + 128 = 167 calories per serving which is same as what is given.
B) percent from carbohydrates per serving = total calories from carbs/total number of calories per serving × 100% = 128/167 × 100% ≈ 77%
C) One box contains 5 servings. Thus total number of calories per box = 167 × 5 = 835 calories
Pounds of force pressing on a rectangle : F = 173.86 lbs
<h3>Further explanation</h3>
Given
P at sea level = 14.7 lbs/in²
Area of rectangle : A = 76.3 cm²
Required
Pounds of force
Solution
P = F/A
F= P.A
Conversion :
1 cm² = 0.155 in²
76.3 cm² = 11.827 in²
Input the value :
F = 14.7 lbs/in² x 11.827 in²
F = 173.86 lbs
