A sample of oxygen gas occupies a volume of 229.5 mL at 762.7 torr pressure. What volume in mL will it occupy at 704.5 torr pressure?

Answers

Answer:

248.4 mL

Explanation:

In order to answer this problem we can use Boyle's law, which states that at a constant composition:

P₁V₁ = P₂V₂

Where in this case:

P₁ = 762.7 torrV₁ = 229.5 mLP₂ = 704.5 torrV₂ = ?

We input the data:

762.7 torr * 229.5 mL = 704.5 torr * V₂

And solve for V₂:

V₂ = 248.4 mL

Q. A small amount of Ferrous sulphate is heated in hard glass tube.

a) Write the balanced chemical reaction involved.

b) Name the type of reaction taking place.​

Answers

Answer:

[tex]a)\ 2FeSO4 \xrightarrow{\text{Heat}} SO_3+SO_2+Fe_2O_3\\b)\ Decomposition\ Reaction[/tex]

Explanation:

Ferrous Sulphate[tex](FeSO4)[/tex] is generally found as Lime-Green Crystals. On heating, these crystals almost immediately turn white-yellow. They then, break down to produce an anhydrous mixture of Sulphur Trioxide [tex](SO_3)[/tex], Sulphur Dioxide [tex](SO_2)[/tex]  as well as Ferric Oxide [tex](Fe_2O_3)[/tex].

We can hence, frame a skeletal equation of this reaction and try to balance it.

Hence,

[tex]FeSO4 \xrightarrow{\text{Heat}} SO_3+SO_2+Fe_2O_3[/tex]

Now,

a)In order to balance it through the 'Hit &Trial Method', we'll follow a series of steps:

1. First, lets compare the number of  Fe (Iron) atoms on the RHS and LHS. We find that, the no. of Fe Atoms on the RHS is twice the number of Fe Atoms on the LHS. We hence, add a co-effecient 2 beside [tex]FeSO_4[/tex].

2. Now, Iron atoms, Sulphur Atoms and Oxygen atoms occur 2, 2, 8 respectively on both the sides:

Hence, As all the other elements as well as iron, balance, we've arrived upon our Balanced Equation :

[tex]2FeSO4 \xrightarrow{\text{Heat}} SO_3+SO_2+Fe_2O_3[/tex]

b) We know that, decomposition reactions are [generally] endothermic reactions in which Large Compounds decompose into smaller elements and compounds. Here, as Ferrous Sulphate decomposes into Sulphur Dioxide, Sulphur Trioxide and Ferric Oxide, the reaction that occurs here is Decomposition Reaction.

Answer:

The sun.

Explanation:

Sun is the ultimate source of energy. All living things on the earth using the energy comes from the sunlight.

Plants using sunlight to fuel the process of photosynthesis. Photosynthesis is the process of transforming of water and carbon dioxide to oxygen and glucose. The amount of energy used to drive the photosynthesis process is stored in the glucose molecules.

Organism feed on plants and breaking down the glucose molecules to release the stored energy. The release energy is utilized by the cells present in the organisms.

Autotrophs also have the ability to make their own food, so they are also using the energy from the sun to make their food.

What is the empirical formula of a compound with a percent composition of 22.5% Phosphorous and 77.5% Chlorine?

Answers

Answer:

[tex]\boxed {\boxed {\sf PCl_3}}[/tex]

Explanation:

We are given the percent composition: 22.5% phosphorus and 77.5% chlorine.

We can assume there are 100 grams of this compound. We choose 100 because we can simply use the percentages as the masses.

22.5 g P 77.5 g Cl

Next, convert these masses to moles, using the molar masses found on the Periodic Table.

P: 30.974 g/mol Cl: 35.45 g/mol

Use the molar masses as ratios and multiply by the number of grams. [tex]22.5 \ g \ P * \frac {1 \ mol \ P }{30.974 \ g \ P}= \frac {22.5 \ mol \ P }{ 30.974} = 0.7264157035 \ mol \ P[/tex]

[tex]77.5 \ g \ Cl * \frac {1 \ mol \ Cl }{35.45 \ g \ Cl}= \frac {77.5 \ mol \ Cl }{ 35.45} \ =2.186177715 \ mol \ Cl[/tex]

Divide both of the moles by the smallest number of moles to find the mole ratio.

[tex]\frac {0.7264157035} {0.7264157035} = 1[/tex]

[tex]\frac {2.186177715}{0.7264157035}=3.009540824 \approx 3[/tex]

The mole ratio is about 1 P: 3 Cl, so the empirical formula is written as: PCl₃

What is heat capacity?

Heat capacity of a substance is the heat energy required to raise the temperature of the substance by one degree celsius.

If the heat capacity is measure per one mole of a substance it is called specific heat capacity. It is an intensive property whereas heat capacity is an extensive property.

The given passage can be completed as follows:

The unit often used in chemistry and physics to measure energy, such as for work or electrical current, is Joule (J). We can also use this unit, as we did in this lab, for measuring  heat capacity.

What is the percent composition (by mass) of MgBr2?

Answers

Answer:

13.2% Mg, 86.8% Br

Explanation:

Mg has a molar mass of 24.31g/mol.

Bromine has a molar mass of 79.90 g/mol.

There is one mole of Mg and two moles of Br in the compound:

79.90x2 + 24.31 = 184.11

So the total molar mass of MgBr2 is 184.11.

A percent tells us a part of a whole, so we will divide each part of the mass into the whole mass.

24.31g Mg / 184.11g MgBr2 = .132

159.8g Br / 184.11g MgBr2 = .868

Multiply these decimals by 100 to make them into a percent.

.132 x 100 = 13.2% Mg

.868 x 100 = 86.8% Br
