how is the miscibility of two liquids related to their polarity?
Answers
Answer:
The more polar the liquid, the more likely that it is miscible with water. The polarity of a liquid does not affect its miscibility with water. The less polar the liquid, the more likely that it is miscible with water. The more polar the liquid, the less likely that it is miscible with water.
Explanation:
hope it helps you
Miscibility of two liquids are directly related to their polarity. The likelihood that a liquid will mix with water increases with its polarity.
What is polarity?Polarity is the arrangement of electrical charge among the atoms connected by a chemical bond. Because both hydrogen atoms in H2 were electrically neutral, bonds among atoms of different elements were electrically inequivalent, as opposed to bonds among identical atoms, which are electrically uniform.
The likelihood that a liquid will mix with water increases with its polarity. Liquid miscibility with water is unaffected by the polarity of the liquid. The likelihood that a liquid will mix with water increases with decreasing polarity. The likelihood that a liquid will be miscible with water decreases with increasing polarity.
Therefore, miscibility and polarity are directly related.

What is oxidation state?
Answers
Answer:
a number assigned to an element in chemical combination which represents the number of electrons lost (or gained, if the number is negative), by an atom of that element in the compound
Explanation:
sodium, magnesium, iron is zero.
The definition of oxidation state is as follows: Oxidation state is a number given to the atom of an element when participating in a chemical reaction.
OXIDATION STATE:The atoms of elements are not always neutral i.e. carry no charge. They sometimes carry either positive or negative charges to become ions. Ions can either be cations (positively charged) or anions (negatively charged). The amount of charges are represented by numbers placed as a superscript in front of the element involved. These superscript charge assigned to a corresponding element during a chemical reaction is called oxidation state. The oxidation state of an element portrays the number of electrons gained or lost during the reaction.Therefore, oxidation state can be defined as a number given to the atom of an element when participating in a chemical reaction.

what aspects are not accounted for in the ideal gas law?
Answers
The aspects not accounted for in the ideal gas law are the force of attraction of the gas molecules on each other and the volume of the gas molecules.
In the ideal gas law, it it assumed that the molecules of the gas are so far away from each other and thus they do not exert a significant force of attraction on each other. Also, the volume of each molecule of gas is neglected and assumed negligible and thus does not account for the overall volume of the gas.
So, the aspects not accounted for in the ideal gas law are the force of attraction of the gas molecules on each other and the volume of the gas molecules.

A fusion reaction always creates which of the following?
a A massive amount of energy.
b A massive amount of heat.
C A more massive atomic nucleus.
d A massive number of smaller nuclei.
Answers
A fusion reaction can be regarded as the type of reaction that occurs where two lighter elements come together in a type of reaction giving rise to a heavier/more massive element.
A fusion reaction always creates a more massive atomic nucleus (option c).
When the two lighter nuclei comes together in a reaction, a more heavier/massive nucleus is formed but its mass will still be less than the combined mass of the two reactant nuclei.
This also indicates that the left over mass may have been released as energy.

Hope this helps :).
When you bend, stretch, or compress an object from its natural shape, it stores Elastic potential energy.
What is elastic potential energy ?Elastic energy is the mechanical potential energy held in a material's or a physical system's configuration as it is subjected to elastic deformation as a result of work being done on it. Elastic energy is created when objects are momentarily crushed, stretched, or otherwise deformed.
Because it is stored in the bonds between atoms of an object or substance when it is momentarily stressed, elastic energy is a type of potential energy. The object may have been stretched or compressed, causing this stress.
An object's shape may change as a result of a force operating on it. If stretched or compressed, elastic things can store elastic potential energy. This occurs, for instance, when a spring is stretched or a catapult is utilized.
Thus, option D is correct.

The water has the following properties H2O molecules are adhesive; they form hydrogen bonds with polar surfaces and Water is a liquid at normal physiological (or body) temperatures because of polarization.
What is polarization?The polarization is a property by which a chemical compound shows the dipole into its nature as one element can attract the electron and attends the partial negative charge and other is electron donating and attends the partial positive charge.
In water molecule it have the tendency to accept the electron because of oxygen electronegativity and can form the bond with hydrogen too as hydrogen donates the electron and behaves as adhesive molecule.

How many cubic meters of carbon dioxide is required to ensure the noncombustibility of a 500-cubic-meter compartment filled with propane vapor
Answers
Answer:
200 m^3
Explanation:
1000m³ of Carbon dioxide is required.
Propane is a type of hydrocarbon that is made up of a single carbon-carbon bond.
Propane burns in oxygen completely in a combustion reaction to produce carbondioxide and water.
The balance equation of combustion of propane gas is:
C3H8(g)+5O2(g)→3CO2(g)+4H2O(g).
But noncombustibility of propane is the incomplete combustion of propane which occurs in absence or insufficient oxygen supply.
The balanced equation for noncombustibility of propane is:
2C3H8 + 9O2 → 4CO2 + 2CO + 8H2O
2 moles of propane = 4 moles of CO2
CO21 mole of propane = 2 moles of CO2 (4moles/2moles)
Therefore 500cm³ of propane = 2 × 500
= 1000cm³
Therefore, 1000m³ of Carbon dioxide is required to ensure the noncombustibility of a 500-cubic-meter compartment filled with propane vapor
