Answer:
false
Explanation:
the hydrosphere is water and water has the biosphere and the geosphere in it.So your answer is false.
Answer:
There are many different types of preservatives like Benzoic acid, Calcium Sorbate, Erythorbic Acid, Potassium Nitrate and Sodium Benzoate. Some act like antioxidants used for slowing down spoilage like Ascorbyl Palmitate, Butylated Hydroxy anisole (BHA) and Butylated Hydroxytoluene (BHT
- 1-ethyl-3-propylcyclopentane
- 1,2-dimethylcyclopentene
- 1,3,5-Triethylbenzene
<h3>What is IUPAC rule?</h3>
The IUPAC nomenclature system is a set of logical rules devised and used by organic chemists to circumvent problems caused by arbitrary nomenclature.
The 1-ethyl-3-propylcyclopentane molecule contains a total of 30 bond(s) There are 10 non-H bond(s), 3 rotatable bond(s) and 1 five-membered ring(s).
The 1,2-dimethylcyclopentene molecule contains two methyl groups and one double bond in the ring.
The 1,3,5-Triethylbenzene molecule contains three ethyl groups and a benzene ring.

Answer:</h3>
259,000 Joules
<h3>
Explanation:</h3>
To calculate the heat energy needed to change 100 grams of liquid water at 75°C to vapor at 225°C, we will do this in steps;
<h3>
Step 1: Heat energy required to raise the temp of water from 75°C to 100°C</h3>
Mass of water = 100 g
Heat capacity of water = 4.184J/g °C
Temperature change (75°C to 100°C) = 25°C
Using the formula to get Quantity of heat;
Q = mcΔT
= 100 g × 4.184 J/g °C × 25°C
= 10,460 joules
<h3>
Step 2: Heat required to change water at 100°C to vapor at 100°C</h3>
Mass of water = 100 g
Heat of vaporization = 2,256 J/g
Heat required to change water to vapor without a change in temperature is given by;
Q = m × Lv
= 100 × 2,256 J/g
= 225,600 Joules
<h3>
Step 3: Heat energy required to raise the temperature of ice from 100°C to 225°C.</h3>
Mass of vapor = 100 g
Specific heat of gas = 1.84 J/g °C
Change in temperature (100°C to 225°C) = 125°C
Therefore;
Q = mcΔT
= 100 g × 1.84 J/g °C × 125°C
= 23,000 joules
<h3>Step 4: Total heat energy required</h3>
Total energy = 10,460 J + 225,600 J + 23,000 J
= 259,060 J
= 259,000 J(approx)
Therefore, heat energy required is 259,000 Joules
