Water contains hydrogen and oxygen. Hydrogen is an explosive gas, while oxygen is a flammable gas. Will the physical properties of water be similar? Why or why not?
Answer:
hope you like it
Explanation:
No, your refreshing glass of water won't spontaneously combust. Water is made up of two elements, hydrogen and oxygen. Hydrogen is flammable, but oxygen is not. ... You can, however, break it down into hydrogen and oxygen by putting energy into it, in the form of an electric current.

Explanation:
Water is added to liquid isopropanol (a polar liquid) to form a solution of rubbing alcohol. Describe what happens on the molecular level as the water dissolves in the isopropanol. Select the correct step order from the drop-down menu for each step listed. The polar isopropanol molecules are attracted to the polar water molecules at the surface of the water. The water molecules spread evenly throughout the solution. The water molecules are carried into the solution. The isopropanol molecules surround the water molecules.
Isopropanol molecules are attracted to water at the surface and surround them. The water gets carried in and gets spread evenly in the solution.
What is the mechanism of water dissolution?A solution is formed when the water and the isopropanol get mixed and dissolved. Isopropanol is a polar solute that dissolves the water molecule in it to form a solution.
The polar molecules of the isopropanol get attracted towards the polar water molecules and start surrounding the water molecules.
The water molecules get carried in the isopropanol in the solution and get evenly dispersed in the solution.
Therefore, water and isopropanol form the solution.

2. Sodium Bicarbonate decomposes when heated to form sodium carbonate, water, and
carbon dioxide gas. If 1.8 moles of carbon dioxide are produced, how many moles of
sodium bicarbonate were decomposed?
Answer:
3.6 moles of sodium bicarbonate were decomposed.
Explanation:
The decomposition of sodium bicarbonate (NaHCO₃) to form sodium carbonate (Na₂CO₃), water, and carbon dioxide gas can be represented by the following balanced chemical equation:
[tex]\displaystyle 2\text{NaHCO$_3$}_\text{(s)} \longrightarrow \text{Na$_2$CO$_3$} + \text{H$_2$O}_\text{($\ell$)} + \text{CO$_2$}_{\text{(g)}}[/tex]
We want to determine the amount of sodium bicarbonate decomposed when 1.8 moles of carbon dioxde is produced.
From the equation, we can see that the mole ratio between carbon dioxide and sodium bicarbonate is 1:2. That is, there is one mole of carbon dioxide produced for every two moles of sodium bicarbonate.
Therefore:
[tex]\displaystyle 1.8\text{ mol CO$_2$} \cdot \frac{2\text{ mol NaHCO$_3$}}{1\text{ mol CO$_2$}} = 3.6\text{ NaHCO$_3$}[/tex]
In conclusion, 3.6 moles of sodium bicarbonate were decomposed.
If you had a mixture of butyric acid and hexane, how would you separate the two compounds?.
Answer:
First of all take separatory funnel.
Add the mixture of compounds into it.
Pour Water into it.
Add NaOH base. This will result in following reaction.
CH₃CH₂CH₂COOH + NaOH → CH₃CH₂CH₂COONa + H₂O
The resulting salt (CH₃CH₂CH₂COONa) is is soluble in water.
The water is the bottom layer (more density) and contains sodium butyrate.
Pour out the water from separatory funnel.
The organic layer (hexane) is left behind.
Now, take the aquous layer and neutralize it using HCl.
Once, neutralized remove the water.

I need help. A chemist wants to dilute 100.0 ml of 2.50 M Sulfuric acid to 0.50 M Sulfuric acid. To what volume must it be diluted?
Taking into account the definition of dilution, to a volume of 500 mL, a solution of 100.0 mL of 2.50 M Sulfuric acid must be diluted to 0.50 M Sulfuric acid.
DilutionWhen it is desired to prepare a less concentrated solution from a more concentrated one, it is called dilution.
Dilution is the process of reducing the concentration of solute in solution, which is accomplished by simply adding more solvent to the solution at the same amount of solute.
In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volume (and weight) of the solution increases.
A dilution is mathematically expressed as:
Ci×Vi = Cf×Vf
where
Ci: initial concentrationVi: initial volumeCf: final concentrationVf: final volumeFinal volumeIn this case, you know:
Ci= 2.50 MVi= 100 mLCf= 0.50 MVf= ?Replacing in the definition of dilution:
2.50 M× 100 mL= 0.50 M× Vf
Solving:
(2.50 M× 100 mL)÷ 0.50 M= Vf
500 mL= Vf
In summary, to a volume of 500 mL, a solution of 100.0 mL of 2.50 M Sulfuric acid must be diluted to 0.50 M Sulfuric acid.

Which statement is correct about the theory of combustion? (1 point)
A. The law of conservation of mass provided justification for the theory of combustion.
B. The theory of phlogiston provided justification for the theory of combustion.
C. The theory of phlogiston became the theory of combustion.
D.The law of conservation of mass became the theory of combustion.
The theory of phlogiston was the first to explain combustion process. J.J Becher was proposed this theory and states the existence of phlogisticated substances contain phlogiston and that they dephlogisticate when burned.
What is combustion ?Combustion is the reaction of gases with atmospheric oxygen producing carbon dioxide and water. Gases like hydrocarbons easily undergoes combustion reaction.
Combustion is an exothermic reaction. Thus, heat is evolved to the surrounding. The conservation of mass is not only for combustion but it is the theory of every reaction.
The phlogiston idea, a debunked scientific hypothesis, suggested that combustible bodies contained a fire-like substance called phlogiston, which was produced after combustion.
Johann Joachim Becher originally put out the concept in 1667, and Georg Ernst Stahl later formalized it. The Phlogiston theory sought to explain a variety of chemical reactions, including burning and rusting Hence, option C is correct.

Why is lifting a box off the ground considered work but carrying a box is not ?
Answer:
In this case the gravitational force is conservative, but the force you exert is not. So, as you lift the box, the work done by non-conservative forces (you) is not zero, and as a result, the total energy of the box increases.
But, Lifting a box is not scientifically considered "work"
Explanation: You do no work against gravity because you are not moving any distance (more accurately displacement) in the direction of the force i.e. the force and displacement are perpendicular once you have lifted the boxes. As work done = force x displacement parallel to the force, no work is done.

Answer:
When two or more atoms are chemically joined together, this is called a molecule. In some cases, such as hydrogen and oxygen, the molecule is made entirely of the same atom, such as hydrogen gas (a molecule) is made entirely of two hydrogen atoms. Here, converting molecules to atoms is as simple as dividing by two.
Atoms can join together - they form bonds together - to make MOLECULES. For example, two atoms of hydrogen hook together to form a molecule of hydrogen
