In Mein Kampf, Hitler asserted the superiority of the Aryan
race.
In 1933, Adolf Hitler was appointed chancellor
of Germany.
The heat absorbed when 2.8 mol NH₄NO₃ is dissolved in water is 71.96 kJ.
<h3>What is heat?</h3>
Heat is the transportation of energy to or from a thermodynamic system.
By the formula of heat

Where n = moles
Delta Hrxn is molar heat
q = heat
Putting the values in the equation

Thus, the heat absorbed when 2.8 mol NH₄NO₃ is dissolved in water is 71.96 kJ.

Well, if you set a ratio, that would mean 4 cups = 5 dozen. That would mean x cups = 15 dozen. To get from 5 to 15 you multiply 3, so the answer is 100!! NO just kidding, the answer is 4 * 3 = 12
1. <u>Too broad:</u> what will the economy be like in the future?
2. <u>Effective:</u> how can virtual reality (VR) be used in health care?
3. <u>Too narrow:</u> how many gallons of water will we use in 2025?
4. <u>Effective:</u> what are the best strategies for <u>increasing</u> food production in the future?
A research question can be defined as a specific inquiry (question) that a research work seeks to provide an answer or response to, especially by using scientific methods such as the following:
- Documenting critical information.
According to their nature, a research question is broadly classified as follows:
1. <u>Too broad:</u> what will the economy be like in the future?
- A country's economy has many facets and as such it would be difficult to write about what it would be like in the future in one research paper.
2. <u>Effective:</u> how can virtual reality (VR) be used in health care?
- Virtual reality (VR) is a modern technology that is effectively used by medical professionals in the field of medicine to provide health care for various patients.
3. <u>Too narrow:</u> how many gallons of water will we use in 2025?
- The quantity of water in gallons that would be used in 2025 can easily be calculated by using a simple formula and as such the answer to this question can be provided in a sentence.
4. <u>Effective:</u> what are the best strategies for <u>increasing</u> food production in the future?
- The best strategies to be adopted for an increase in food production in the future can be developed into a full research paper based on strategies that have been used in the past.

Classifying each label into the correct category of human red blood cell
A) Human red blood cell shrinks
- Cells placed in hypertonic solution
- More water moves out of cell
B) Normal Human red blood cell
- Cell placed in isotonic solution
- Water enters and leaves at the same rate
C) Human red blood cell swells
- Cell placed in hypotonic solution
- More water moves into cell
<h3>Types of solution</h3>
A hypertonic solution is a solution with a higher concentration to its surroundings ( i.e contains more solutes like electrolytes than its surroundings ). when a cell is placed in such solution is shrinks gradually and dies off through a process known as plasmolysis. while a hypotonic solution is a direct opposite of a hypertonic solution. Also An isotonic solution is a solution with the same concentration with its surrounding solution.
Hence we can conclude that the classification of each label into the appropriate category are as listed above.
