What is the molality of a solution containing 5 moles of a solute and 13 kg of a solvent?
Answer:
Morality of a solution = 0.38461
Explanation:
Given:
Amount moles in solution = 5 moles of solute
Amount of solvent = 13 kg
Find:
Morality of a solution.
Computation:
⇒ Morality of a solution = Amount of mole solute / Amount of solvent
⇒ Morality of a solution = 5 / 13
⇒ Morality of a solution = 0.38461
⇒ Morality of a solution = 0.385 (Approx)

When k-37 undergoes positron emission what is the resulting atom
Answer:
The resulting atom is argon
Explanation:
Positron emission is a type of radioactive decay known as beta plus decay. This reaction is characterized by an element having an increase in the number of neutrons and a decrease in the number of protons.
This affects the atomic number in which it is decreased by one while the mass number remains unchanged.

How do ethics affect scientific research?
A. Scientists should be forced to ignore their own ethical values
when doing research.
B. Scientists should not be allowed to conduct research that is
harmful to others.
C. Scientists should not let ethical issues limit scientific
advancement.
D. Ethics should be discussed in religion or philosophy but not in
science.
SUBMIT
Answer:
The answer is B.
Explanation:
Ethical concerns affect scientific research when scientists or groups of scientists let their personal bias or political persuasions affect the research being conducted. Scientific ethics involve doing experimentation and analysis of data without bias no matter what the conclusions point to.
Ethical principles dictate that researchers have a responsibility to ensure that their work does not cause harm to human beings, animals, or the environment. The correct answer is B. Scientists should not be allowed to conduct research that is harmful to others.
Research involving human subjects, for example, must adhere to strict ethical guidelines, such as informed consent and minimizing risks. Ethical review boards or committees often evaluate research proposals to ensure that potential harm is minimized or avoided.
Ethics significantly affect scientific research by guiding researchers to conduct their work responsibly, ensuring the well-being of individuals and society, and addressing potential conflicts between scientific advancement and ethical principles.
Therefore, the correct answer is B. Scientists should not be allowed to conduct research that is harmful to others.

the reaction below shows a system in equilibrium how would an increase in the concentration of chemicals affect this reaction?
Answer:
Option B. The equilibrium of the reaction would shift to the right.
Explanation:
According to Le Chatelier's principle, when an external constrain such as change in concentration, temperature or pressure is imposed on a chemical system in equilibrium, the equilibrium position will shift in order to neutralize the effect.
Now, let us answer the question above.
From the question given above, the equation is:
A + B <===> C + D
Increasing the concentration of A will shift the equilibrium position to the right.
This is true because increasing the concentration of A means having more reactants in the system. So the reactants react to produce more product thereby shifting the equilibrium position to the right.

What is the volume of a 4.0M solution that contains 374 grams of KNO3?'
Answer:
0.93L
Explanation:
We'll begin by calculating the number of mole of present 374g of KNO3. This is illustrated below:
Mass of KNO3 = 374g
Molar mass of KNO3 = 39 + 14 + (16x3) = 101g/mol
Number of mole of KNO3 =..?
Mole = Mass /Molar Mass
Number of mole of KNO3 = 374/101 = 3.7 moles
Now, we can calculate the volume of the solution as follow:
Mole of KNO3 = 3.7 moles
Molarity = 4M
Volume =..?
Volume = mole /Molarity
Volume = 3.7/4
Volume = 0.93L
Therefore, the volume of the solution is 0.93L
Answer:
THE VOLUME OF A 4 M SOLUTION THAT CONTAINS 374 g OF KNO3 IS 0.93 L
Explanation:
Number of moles = concentraion * volume
Number of moles can also be written as:
number of moles = mass / molar mass
Calculate the molar mass of KNO3 where (K = 39, N = 14, 0=16)
molar mass of KNO3 = (39 + 14 + 16*3) = 101 g/mol
So therefore:
mass / molar mass = concentration * volume
where;
mass = 374 g
molar mass = 101 g/mol
concentration = 4 M
volume = unknown
Hence,
374 / 101 = 4 * V
V = 374 / 101 * 4
V = 374 / 404
V = 0.9257 dm3
The volume of a 4M solution that contains 364 g of KNO3 is approximately 0.93 L
