A balloon that had a volume of 3.50 L at 25.0°C is placed in a hot room at 40.0°C. If the pressure remains constant at 1.00 atm, what is the new volume of the balloon in the hot room?
Answers
Ideal gas law is valid only for ideal gas not for vanderwaal gas. Charles' gas law is used here. Therefore the new volume of the balloon in the hot room is 3.68 L.
What is ideal gas equation?
Ideal gas equation is the mathematical expression that relates pressure volume and temperature. Vanderwaal gas can behave as ideal gas low pressure and high temperature.
Mathematically the relation between Pressure, volume and temperature can be given as
PV=nRT
where,
P = pressure of gas
V= volume of gas
n =number of moles of gas
T =temperature of gas
R = Gas constant = 0.0821 L.atm/K.mol
Combining Boyle's and Charles' gas law
V₁/T₁ = V₂/T₂
3.50 L ÷298 K = V₂÷313 K
V₂ = 3.68 L
Therefore the new volume of the balloon in the hot room is 3.68 L.

C3H8 + 5O2 = 3CO2 + 4H2O
We are given the amount of C3H8 to be reacted with O2. This will be the starting point of the calculations.
73.7 g C3H8 ( 1 mol C3H8/ 44.1 g C3H8 ) ( 5 mol O2 / 1 mol C3H8 ) ( 32.0 g O2 / 1 mol O2 ) = 267.39 g O2
Answer: 267.2 grams
Explanation:
According to stoichiometry:
1 mole of require 5 moles of
Thus 1.67 moles of will require =
of
Mass of
Thus 267.2 grams of oxygen are required.

(2) Magnesium conducts electricity.
(3) Magnesium reacts with an acid.
(4) Magnesium has a high boiling point.
Answers
Justification:
1) Malleability, conduction of electricity, and boiling point are physical properties.
2) Maleability is the ability to be transformed into foil. It is just a change in form. So, it is a physical property.
3) The metals conduct electricity in virtue of the array of the atoms, which permtis the flow of the electrons, but it does not involve a chemical change, so it remains being a physical proerty.
4) Boling point is the temperature at which a substance passes from liquid state to gas state, which are just different forms of the same substance. So, it is other physical property.
5) Reaction with an acid is indeed a chemical transformation: the metal (magnessium) will form a chemical bond with some spieces of the acid to form a new compound. This is a chemical reaction in virtue of the chemcial properties of the substance (its ability to react with acids)
Magnesium reacts with an acid.

The answer is: metallic bonding.
Potassium (K) is alkaline metal.
Metallic bond is a type of chemical bond.
Metallic bond is formed between electrons and positively charged metal ions.
Metallic radius is defined as one-half of the distance between the two adjacent metal ions.
Metallic bond increace electrical and thermal conductivity.
Metals conduct heat, because when free moving electrons gain energy (heat) they vibrate more quickly and can move around.
is present in solid potassium.
Further Explanation:
The chemical bond is a link or connection between the atoms present in molecules or between ions and molecules in the crystals. It is responsible to hold the chemical substances together and for the formation of chemical compounds.
Types of chemical bonds:
Covalent bond
This is also known as a molecular bond. It is the chemical bond that results from the electron sharing between the atoms. The compounds resulting from such bonds are called covalent compounds.
Ionic bond
The type of chemical bond that is formed due to the transfer of electrons from one atom to the other is an ionic bond. Ions are produced in the formation of such bonds. The electropositive element forms cations by the loss of electrons while anions are formed by the electronegative element.
Metallic bond
As is evident from its name, this bond exists in metals. Here, electrons are delocalized throughout the metal and are not only shared between two atoms. So the free electrons are present within the sample. Due to the presence of free electrons, metals have high conductivity. This bond is an attraction between the positive ions and the electrons of the same metal.
Potassium belongs to group 1A of the periodic table that is located at the extreme left region of the table. Since metals are present at the leftmost part of the periodic table, potassium is an alkali metal. So metallic bonding is present in solid potassium.
