<span>Chemical Energy is energy stored in the bonds of chemical compounds (atoms and molecules). It is released in a chemical reaction, often producing heat as a by-product (exothermic reaction). Batteries, biomass, petroleum, natural gas, and coal are examples of stored chemical energy.

Answer:1 2and 3
Explanation:
Saccharide consist of simple sugars of triose
The new pressure is 1.08 atm
<h3>Gas law </h3>
From the question, we are to determine the new pressure
Using the General gas equation,
Where P₁ is the initial pressure
V₁ is the initial volume
T₁ is the initial temperature
P₂ is the final pressure
V₂ is the final volume
and T₂ is the final temperature
From the given information,
P₁ = 1.5 atm
V₁ = 15 L
T₁ = 105 C = 105 + 273.15 = 378.15 K
V₂ = 25 L
T₂ = 181 C = 181 + 273.15 = 454.15 K
P₂ = ?
Putting the parameters into the equation, we get
P₂ = 1.08 atm
Hence, the new pressure is 1.08 atm

Answer:
[D] Same Phylum
Explanation:
To know the least closely related We need to the know this:
- Domain
- Kingdom
- Phylum
- Class Order
- Family
- genus
- Species
Domain → Broadest ⇒ Least related.
Thus, In the answer choices we know that Phylum is the least Closely related.

Answer:
These are three different forms of expressing a volume of 2000 ml:
Explanation:
The expression 2000 ml means 2000 mililiters and convey three important informations:
- The unit, which is mililiter (1 ml = 1 / 1,000 liter)
- The magnitude, which is 2000
- The precision: the zeros to the right of the figure 2 are not significative, so this magnitue is precise only to the thousands units. This means, that the measure could be between 1500 and 2499 (ml).
You might express the same volume with a different unit, e.g. liter, and in a different way (using scientific notation).
<u>1) Changing the unit.</u>
To change ml to liter you must multiply for the conversion factor:
Thus, 2000 ml is equal to:
- 2000 ml × 1 liter / 1,000 ml = 2 liter
<u>2) Using scientific notation:</u>
You change the number to a power of ten, using a decimal greater than or equal to 1 and less than 10.
For 2000 the decimal is 2. and the power of ten is 3 (for the three zeros after the 2):
