Explanation:
What is the purpose of the scientific method?
<em><u>ans/</u></em>
the goal of any scientific method is to solve a problem or to better understand an observed event.
b.
i. What does the law of conservation of energy say?
<em><u>ans/</u></em>
The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another.
ii. List two different kinds of energy.
<em><u>ans/</u></em>
Potential energy.
Kinetic energy.
iii. What does the law say about changes energy can undergo?
<em><u>ans/</u></em>
The implication of the Law of Conservation of Energy is that for any energy conversion, if a certain type, or form, of energy gets reduced by a certain amount, then another type of energy must increase by the same amount.
A salt derived from a weak base and a strong acid will yield an acid salt
Answer:
The answer to your question is 0.4 moles of Oxygen
Explanation:
Data
Octane (C₈H₈)
Oxygen (O₂)
Carbon dioxide (CO₂)
Water (H₂O)
moles of water = ?
moles of Oxygen = 1
Balanced chemical reaction
C₈H₈ +10O₂ ⇒ 8CO₂ + 4H₂O
Reactant Element Products
8 C 8
8 H 8
20 O 20
Use proportions to solve this problem
10 moles of Oxygen ----------------- 4 moles of water
1 mol of Oxygen ------------------ x
x = (4 x 1) / 10
x = 4 / 10
x = 0.4 moles of water
Depending in the category of the Hurricane, you make experience different levels of wind power and destruction. Hurricanes only have 5 categories ranking from Category 1 to Category 5. The smallest category is category 1 making category 5 the largest. The bigger the category, the more wind or destruction you'll experience.
