The scientific question related to the game of basketball is option D: "Do teams that practice more win more games?"
This question is scientific because it explores a cause-and-effect relationship between practice and game outcomes. It can be investigated through empirical observation and data analysis.
To answer this question, researchers could collect data on the practice hours of different basketball teams and compare them to their corresponding game performance. Statistical analysis could be used to determine if there is a correlation between practice time and winning percentage or other performance metrics.
By examining a large sample of teams over an extended period, researchers could draw conclusions about the impact of practice on game outcomes. This scientific inquiry would contribute to the understanding of the factors that influence team success in basketball and could potentially inform training strategies and coaching techniques.

is a dibasic acid the same as a strong acid
Answer:-
Since all the acid molecules have split into ions, there will be more H+ ions in a strong acid than a weak acid, hence it's pH is lower! E.g. Hydrochloric acid HCl, nitric acid HNO3. If one mole of an acid is neutralised by 2 moles of NaOH, then the acid is dibasic!

PLEASE HELP 100 POINTS!!!!!! Read the short section below on the difference between everyday experience and science.
Everyday Experience vs. Science
The process of science can sound very similar to how you experience life. However, everyday human experience and science are very different. Science has procedures with special conditions and rules for making observations. People do not have such restrictions in everyday life. Individuals can witness events, make adjustments, and practice trial and error similar to scientists. Unlike scientists, individuals are free to do tests using any method they choose. People can try different ways of doing things like driving, cooking, and working out. Then, they can modify their procedures to get the results they want.
Unlike the public, scientists perform trial and error by doing carefully designed experiments. Their experiments require the proper methods and tools. In addition, their projects undergo review by their peers. Even though some science observations take place in a natural environment, they do so for a brief period of time or in a limited area. Much of science must be completed in an artificial environment to reduce the number of variables that can affect the experimental process. Though scientists change factors within their research, they do not usually change the results of their experiments. Good scientists ensure that their own wants and preferences do not affect the knowledge they discover.
Despite having different purposes and abilities, both everyday experiences and science are important. Many key scientific discoveries were started with someone’s everyday experiences. Everyday experiences influence the decisions and direction people take in life. The steps scientists follow in investigations influence information; they provide a way of knowing about the world and explaining how it works.
In your opinion, are scientists born or made? How can everyday people challenge or extend scientific ideas and make scientific discoveries? Use excerpts from the section to explain and support the reasoning behind your answer.

c. The reaction Br2 (l) --> Br2 (g) has ΔH = 30.91 kJ/mol and ΔS = 93.3 J/mol·K. Use this information to show (within close agreement) that the boiling point of bromine is 332 K.
The boiling temperature of bromine is 331.29 K
Explanation:
From the question given above, the following data were obtained:
Br₂ (l) —> Br₂(g)
Enthalpy change (ΔH) = 30.91 KJ/mol
Entropy change (ΔS) = 93.3 J/mol·K
Boiling temperature (T) =?Next, we shall convert 30.91 KJ/mol to J/mol. This can be obtained as follow:
1 KJ/mol = 1000 J/mol
Therefore,
30.91 KJ/mol = 30.91 × 1000
30.91 KJ/mol = 30910 J/mol
Thus, 30.91 KJ/mol is equivalent to 30910 J/mol.
Finally, we shall determine the boiling temperature of bromine. This can be obtained as follow:
Enthalpy change (ΔH) = 30910 J/mol
Entropy change (ΔS) = 93.3 J/mol·K
Boiling temperature (T) =?ΔS = ΔH / T
93.3 = 30910 / T
Cross multiply
93.3 × T = 30910
Divide both side by 93.3
T = 30910 / 93.3
T = 331.29 K
Thus, the boiling temperature of bromine is 331.29 K

The diameter of neutral atoms generally decreases going left to right across one period on the periodic table. What change causes this decrease in diameter of atoms?
Explanation:
Atomic size gradually decreases from left to right across the periodic table because within a period of elements, all electrons are added to the same shell. However, at the same time, protons are being added to the nucleus, making it more positively charged. The effect of increasing proton number is greater than that of the increasing electron number. Therefore, there is a stronger nuclear attraction. This means that the nucleus attracts the electrons more strongly, pulling the atom's electron shells closer to the nucleus. As a result, the atomic diameter of the atom decreases.
What is the pressure of 4 moles of helium in a 50 L tank at 308 K?
Use PV = nRT.
A. 24.64 atm
B. 0.13 atm
O C. 0.51 atm
D. 2.02 atm
Answer:
D
Explanation:
P = Pressure
V = Volume
n = Moles
R = .08206 (because we're using liters)
T = Temperature (as K)
P(50) = (4)(.08206)(308)
P(50) = 101.09792
Divide both sides by 50
P(50)/50 = 101.09792/50
P = 2.0219584
Answer:
[tex]\boxed {\boxed {\sf D. \ 2.02 \ atm}}[/tex]
Explanation:
We are asked to find the pressure of helium gas using the ideal gas law.
[tex]PV= nRT[/tex]
In this formula P is the pressure, V is the volume, n is the number of moles of gas, R is the universal gas constant, and T is the temperature.
The pressure is unknown and we are solving for it. The volume is 50 liters, there are 4 moles of helium gas, the universal gas constant is 0.08206 L *atm/ mol * K, and the temperature is 308 Kelvin.
[tex]\bullet \ V= 50 \ L \\\bullet \ n= 4 \ mol \\\bullet \ R = \frac {0.08206 \ L * atm}{mol *K}\\\bullet \ T= 308 \ K[/tex]
Substitute these values into the formula.
[tex]P * 50 \ L= 4 \ mol * \frac {0.08206 \ L * atm}{mol *K} * 308 \ K[/tex]
Multiply on the right side. The units of moles (mol) and Kelvin (K) cancel each other out.
[tex]P* 50 \ L = 4 * 0.08206 \ L *atm * 308[/tex]
[tex]P*50 \ L =0.32824 \ L * atm *308[/tex]
[tex]P* 50 \ L = 101.09792 \ L * atm[/tex]
We are solving for the pressure, so we must isolate the variable P. It is being multiplied by 50 liters. The inverse operation of multiplication is division, so divide both sides by 50 L.
[tex]\frac {P* 50 \ L}{50 \ L} = \frac {101.09792 \ L * atm}{50 \ L}[/tex]
[tex]P= \frac {101.09792 \ L * atm}{50 \ L}[/tex]
The units of liters (L) cancel.
[tex]P= \frac{101.09792}{50 } \ atm[/tex]
[tex]P= 2.0219584 \ atm[/tex]
If we round to the nearest hundredth place the 1 in the thousandth place tells us to leave the 2 in the hundredth place.
[tex]P \approx 2.02 \ atm[/tex]
The pressure is approximately 2.02 atmospheres and choice D is correct.
Write down the importance of nitrogen for plants
Explanation:
People also ask
What is the importance of nitrogen for plants?
Nitrogen is an essential macronutrient for plant function and is a key component of amino acids, which form the building blocks of plant proteins and enzymes. Proteins make up the structural materials of all living matters and enzymes facilitate the vast array of biochemical reactions within a plant.
Answer:
Nitrogen is vital because it is a major component of chlorophyll, the compound by which plants use sunlight energy to produce sugars from water and carbon dioxide(i.e.,photosynthesis). It is also a major component of amino acids, the building blocks of proteins. Without proteins, plants wither and die.
