Answer:
While organic chemistry is defined as the study of carbon-containing compounds and inorganic chemistry is the study of the remaining subset of compounds other than organic compounds, there is overlap between the two fields (such as organometallic compounds, which usually contain a metal or metalloid bonded directly to carbon).

At the Sprite bottling plant where the temperature is at 235K, each bottle can hold 3.80 atm of pressurized carbon dioxide gas (to make the soda fizzy). At room temperature 298K what is the new pressure?
Answer:
P2 = 4.76 atm
Explanation:
Given:
T1 = 235K. P1 = 3.80 atm
T2 = 298K. P2 = ?
Here, we use Gay-Lussac's law:
P1/T1 = P2/T2
Solving for P2, we get
P2 = (T2/T1)P1
= (298K/238K)(3.80 atm)
= 4.76 atm

what is the [H+] concentration of a solution with a pH of 3.78
Answer:
[H+] = 1.66 x [tex]10^{-4}[/tex]
Explanation:
To find the [H+] concentration of a solution, we can use the formula:
[tex][H+] = 10^{-pH}[/tex]
Let's plug in the pH.
[tex][H+] = 10^{-3.78}[/tex]
Evaluate the exponent.
[H+] = 1.66 x [tex]10^{-4}[/tex]

What is a yield. in your own words but be more detailed about what you say.
Answer:
Yield is the income on an investment over a period of time. It is calculated by taking interest or dividends earned by the investment, then dividing them by the value of the investment. It's usually expressed as an annual percentage, and excludes capital gain, which are the profits earned from buying something at one price and selling it at a higher price.

If a gas occupies 2.3 liters at a pressure of 1.9 atm, what will be its volume at a
pressure of 3.8 atm?
Answer:
Option C (1.2 L) is the correct option.
Explanation:
The given values are:
Pressure,
[tex]P_1=1.9 \ atm[/tex]
[tex]P_2=3.8 \ atm[/tex]
Volume,
[tex]V_1=2.3 \ L[/tex]
[tex]V_2=?[/tex]
As we know,
The gas equation is:
⇒ [tex]PV=nRT[/tex]
At constant temperature,
⇒ [tex]P_1 V_1=P_2 V_2[/tex]
or,
⇒ [tex]V_2=\frac{P_1 V_1}{P_2}[/tex]
By substituting the values, we get
⇒ [tex]=\frac{1.9\times 2.3}{3.8}[/tex]
⇒ [tex]=\frac{4.37}{3.8}[/tex]
⇒ [tex]=1.15 \ L[/tex]
or,
⇒ [tex]=1.2 \ L[/tex]
If a solid is added to a liquid until no more of the solid will dissolve
......... solution is formed.
Answer:
If a solid is added to a liquid until no more of the solid will dissolve saturated solution is formed.
According to the concept of solubility, if a solid is added to a liquid until no more of the solid will dissolve saturated solution is formed.
What is solubility?Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.
The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

1: A50 L balloon is at 4 atm of pressure. What is the volume at 2 atm of pressure?
Answer:
100 L
Explanation:
Use Boyle's Law, p1v1 = p2v2.
p1 = 4 atm
v1 = 50L
p2 = 2 atm
v2 = ?
p1v1 = p2v2
(4 atm) (50L) = (2 atm) (v2)
v2 = (4 atm)(50L) / (2 atm) = 100 L

Fluorine (F) has an atomic number of 9 and an atomic weight of 18.99. Fluorine has _____.
at least one isotope
10 neutrons
18 electrons
9 protons
an atomic mass of 19
Answer:
9 protons
Explanation:
By looking at the periodic table, you will see that Fluorine has 9 protons. Since the number of electrons equal the number of protons, Fluorine has 9 electrons as well. Meanwhile, it's mass number of 19, minus 10 neutrons, gives you 9 protons or electrons. Hence, the atom would be Fluorine.

Explanation:
amount of baking soda = 2.01 g
---> 2.01 g NaHCO3 × (1 mol NaHCO3/84.007 g NaHCO3)
= 0.024 mol NaHCO3
mass of the product = 1.28 g
Possible reactions:
NaHCO3(s) ---> NaOH(s) + CO2(g)
0.024 mol NaHCO3 × (1 mol NaOH/1 mol NaHCO3)
= 0.024 mol NaOH × (39.997 g NaOH/1.mol NaOH)
= 0.96 g NaOH
2NaHCO3(s) ---> Na2O(s) + 2CO2(g) + H2O(g)
0.024 mol NaHCO3 × (1 mol Na2O/2 mol NaHCO3)
= 0.012 mol Na2O × (61.9789 g Na2O)
= 0.73 g Na2O
2NaHCO3(s) ---> Na2CO3(s) + CO2(g) + H2O(g)
0.024 mol NaHCO3 × (1 mol Na2CO3/2 mol NaHCO3)
= 0.012 mol Na2CO3 × (105.9888 g Na2CO3/1 mol Na2CO3)
= 1.27 g Na2CO3
Conclusion:
Based on the mass of the product in the crucible and comparing it with the predicted product mass in different reactions, I conclude that Na2CO3 is the most likely product in the crucible.
