what is the final pressure (in atm) of 5.25 L gas initially at 534 mmHg and 22 degrees celsius that is compressed to a final volume of 2.75 L at a new temperature of 15 degrees celsius?
Answers
The final pressure of 5.25L gas initially at 534 mmHg and 22 degrees celsius that is compressed to a final volume of 2.75 L is 1.31atm.
How to calculate pressure?The combined gas law states that the ratio of the product of pressure and volume and the absolute temperature of a gas is equal to a constant.
The pressure of a gas can be calculated by using the combined gas law equation as follows:
P₁V₁/T₁ = P₂V₂/T₂
Where;
P₁ = initial pressure (atm)V₁ = initial volume (L)T₁ = initial temperature (K)P₂ = final pressure (atm)V₂ = final volume (L)T₂ = final temperature (K)According to this question, a 5.25 L gas initially at 534 mmHg and 22 degrees celsius is compressed to a final volume of 2.75 L at a new temperature of 15 degrees celsius. The final pressure can be calculated as follows;
22°C = 295K15°C = 288K534 mmHg = 0.703 atm0.703 × 5.25/295 = P₂ × 2.75/288
0.0125 = 0.00955P
P₂ = 1.31atm
Therefore, 1.31 atm is the final pressure of the gas compressed to a lower volume of 2.75L.

Strontium metal and aqueous HCIreact to give hydrogen gas andaqueous strontium chloride. Writethe balanced chemical equation usingthe correct chemical formulas for thereactants and products and identifythe reaction type.
Answers
The metal Strontium is symbolized by Sr, and since it is a metal its oxidation number is 0, so no charge.
In this reaction, the Sr will become 2+, so, since Cl is 1-, the proportion is 1 Sr to 2 Cl, so the unbalanced reaction is:
[tex]Sr+HCl\to H_2+SrCl_2[/tex]To balance it, we need to add a coefficient of 2 on HCl, so we have 2 H on both sides and 2 Cl on both sides.
The Sr is and continue balanced.
So, the balanced reaction is:
[tex]Sr+2HCl\to H_2+SrCl_2[/tex]As we can see, the left part has Sr alone and H with Cl, while on the right side this changes, H is alone and Sr is with Cl. This means that Cl was displaced from H to Sr, so this is a single displacement reaction.

Each row is independent from the other, so we can use the same method for each one.
Le'ts give a variable for each column:
- S: Symbol
- z: Z (Atomic number)
- a: A (Mass number)
- p: No of Protons
- e: No of Electrons
- n: No of Neitrons
- c: Charge
In the symbol column, the right supercript is the charge, so since the Symbol is:
[tex]S=Mg^{2+}[/tex]The charge is 2+. We write as 2+, but in math we would write as +2, they are the same, but in different notations.
[tex]c=2+=+2[/tex]The atomic number and the symbol are always unique, so each element has always the same atomic number and the other way around too.
From a periodic table, we can see which Element corresponds to which atomic number Z.
On a periodic table, we can see that the atomic number of Mg is 12, so:
[tex]z=12[/tex]Also, the atomic number and the number of protons is always the same:
[tex]\begin{gathered} p=z \\ p=12 \end{gathered}[/tex]The mass number, a, is alwais the number of protons plus the number of neutrons:
[tex]a=p+n[/tex]Since we know that the mass number is 25 in this case, we can calculate the number of protons:
[tex]\begin{gathered} a=p+n \\ 25=12+n \\ n=25-12 \\ n=13 \end{gathered}[/tex]So it checks out with the number on the table.
Each proton has a charge of 1+ and each electron has a charge of 1-. In Math terms, we can say that each proton counts as +1 and each electron counts as -1.
Thus, the charge is the number of protons minus the number o electrons:
[tex]c=p-e[/tex]Since the charge is 2+ and there are 12 protons, we can say:
[tex]\begin{gathered} 2=12-e \\ e=12-2 \\ e=10 \end{gathered}[/tex]So, there are 10 electrons.
Putting altogether, we have:
[tex]\begin{gathered} S=Mg^{2+} \\ z=12 \\ a=25 \\ p=12 \\ e=10 \\ n=13 \\ c=2+ \end{gathered}[/tex]And, by the names:

The volume of fluorine is 510.52L
STEP-BY-STEP EXPLANATION:
From the question provided, you were given the mass of fluorine to be 432.8 grams.
Given information
Mass of fluorine = 432.8 grams
To find the volume of Fluorine, we need to find the mole of fluorine from the mole formula
[tex]\text{Mole = }\frac{\text{ reacting mass}}{\text{ molar mass}}[/tex]From the periodic table, the molar mass is 18.99 g/mol
The next thing is to substitute the data into the formula
[tex]\begin{gathered} \text{Mole = }\frac{\text{ 432.8}}{18.99} \\ \text{Mole = }22.79\text{ moles} \end{gathered}[/tex]Since the mole of fluorine is 22.79 moles, then, we can now find the volume of fluorine.
At STP, 1 mole is equivalent to 22.4L
Let the volume of fluorine be x
[tex]\begin{gathered} 1\text{ mole }\rightarrow\text{ 22.4L} \\ 22.79\text{ moles }\rightarrow\text{ xL} \\ \text{Cross multiply} \\ 1\cdot\text{ x = 22.4 }\cdot\text{ 22.79} \\ x\text{ = 510.52L} \end{gathered}[/tex]The volume of fluorine is 510.52L

An oxidizing agent is a substance that "accepts" or "receives" an electron from a reducing agent in a redox chemical process. Therefore, an oxidant is any chemical that oxidizes another substance.
An electron is "donated" to an electron acceptor by a chemical species known as a reducing agent. Chemicals that are often used as reducing agents include the Earth metals, formic acid, oxalic acid, and sulfite compounds.

REACTION: C5H12 + 8O2 5CO2 + 6H2O When 25.5 grams of C5H12 are consumed in this reaction what mass of CO2 can be produced in grams?
Answers
In order to answer this question we will need the properly balanced reaction, which the question already gave us:
C5H12 + 8 O2 -> 5 CO2 + 6 H2O
Then we need to focus on the compounds that the question is asking, which are C5H12 and 5 CO2, from the reaction we can also identify the molar ratio between both molecules, 1:5, that means that for every mole of C5H12, we will end up with 5 moles of CO2
Now let's find out how many moles of C5H12 are in 25.5 grams of it, we will use its molar mass to find the answer, molar mass is 72.15 g/mol
72.15 g = 1 mol
25.5 g = x moles
x = 0.35 moles of C5H12
Now we have 0.35 moles of C5H12, we know that molar ratio is 1:5, now let's see how many moles of CO2 we will have
1 C5H12 = 5 CO2
0.35 C5H12 = x CO2
x = 1.75 moles of CO2
And now we will do a similar step using CO2 molar mass in order to find the final mass, molar mass for CO2 is 44.01 g/mol
44.01 g = 1 mol
x grams = 1.75 moles
x = 77.02 grams of CO2

Therefore,
a) The precipitate X that is formed would be BaSO₄ in the above scheme.
b) The cation that is left at Y is Ag⁺.
c) This reaction can also be carried out using NaCl and NaSCN. By using NaCl we could obtain, BaCl₂ and by using NaSCN we could get Ba(SCN)₂. Here both precipitates are soluble. The respective reactions are,

consider the reactants and propose the right side of the equation.
Mg + H2SO4 ➡️
Answers
The reaction involving the reactants Magnesium and Sulphuric acid results in the formation of Magnesium sulphate and hydrogen
Mg (s) + dil. H2SO4 (aq) ➡️ MgSO4 (aq) + H2 (g)
Magnesium is a solid compound. When magnesium reacts with dilute sulphuric acid, it forms aqueous magnesium sulphate and hydrogen gas.
The type of reaction involved is single replacement reaction with both oxidation and reduction happening simultaneously. During the process, heat would be released becoming an exothermic reaction.
If concentrated sulphuric acid is used in place of dilute sulphuric acid, magnesium would react with concentrated sulphuric acid and forms 3 products namely magnesium sulphate, Sulphurdioxide and Water.
