Answer:
See explanation
Explanation:
To convert from atm to mmHg
1 atm = 760 mmHg
0.799 atm = 0.799 atm * 760 mmHg/1 atm = 607.24 mmHg
To convert from atm to torr
1 atm = 760 torr
0.799 atm = 0.799 atm * 760 torr/1 atm = 607.24 torr
help, please? What science law explains why there should always be the same type of elements on the reactant side as there are on the product side? What does this law state? (HINT: Answer both of these questions. A: The Law of _________________ states that _____________.)
Answer:
the law of conservation of energy states that energy neither created nor destroyed that means in a chemical reaction Mass reactants ( starting material)=tomass of produt

How many grams of water should be added to 4.00 g NaOH to create 2.00% by mass NaOH solution?
Answer:
196 grams
because ^^^ was wrong and person in comments said it was 196 and it was right
When NaOH of 4.00 g is being added with water, the mass of water required to create 2.00% of NaOH solution by mass is 196 g.
What is mass percent of solute?It means that the particular amount of solute in terms of percentage is present in the solute.
Given the mass of the solute, NaOH is 4.00g
Suppose the mass of water required to add is x in g.
The mass percent of the solute is
[tex]\dfrac{2}{100} =\dfrac{4.00}{4.00 +x }[/tex]
x =196 g
Therefore, mass of water required to create 2.00% of NaOH solution by mass is 196 g.

How can we understand the historical development of the Periodic Table and apply its predictive power?
Extension Questions: Describe different chemical principles and systems. How does the layout of the periodic table allow you predict other element's properties? Consider all types and groups of elements.
Why is it important to know and understand the historical development of atomic theory?
Extension Questions: How does the atom relate to the elements of the periodic table? What are your most common models and how do they relate to the current atomic model? What theories don’t hold true today if any?
How do atoms combine to form ionic, covalent, and metallic bonds?
How can we write and balance chemical equations using the law of conservation of mass?
Answer:
Chemistry is important because everything you do is chemistry! Even your body is made of chemicals. Chemical reactions occur when you breathe, eat, or just sit there reading. All matter is made of chemicals, so the importance of chemistry is that it's the study of everything.
