Answer:
Decrease order of speed of atoms in solid state, liquid state and gaseous states: gas > liquid> solid
Decreasing order of space of atoms in solid state, liquid state and gaseous states: gas > liquid> solid
Explanation:
Solid state : In this state, the particles are closely packed and does not have any space between them. They have least kinetic energy due to restricted movement. This state has a definite shape and volume.
Liquid state : In this state, particles are present in random and irregular pattern. The particles are closely arranged but they can move from one place to another and thus have higher kinetic energy as compared to solids. This state has a definite volume but does not have a fixed shape.
Gaseous state : In this state, particles are loosely arranged and have a lot of space between them. They have highest kinetic energy. This state has indefinite volume as well as shape.
Decrease order of speed of atoms in solid state, liquid state and gaseous states: gas > liquid> solid
Decreasing order of space of atoms in solid state, liquid state and gaseous states: gas > liquid> solid
Answer: In the following equation, is considered as a binary compound.
Explanation: A binary compound is considered as a compound having 2 elements only. In the following chemical equation:
There are 2 compounds present because compound is defined as the chemical combination of two or more elements in a fixed ratio.
In the equation, compounds are: and
consists of 2 elements which are hydrogen and oxygen and hence is considered as a binary compound.
consists of 3 elements which are sodium, hydrogen and oxygen and hence, cannot be considered as a binary compound.
Answer: a contest in which you are eliminated if you fail to spell a word correctly.
B) an atom with 6 protons and 6 neutrons - an atom with 6 protons and 7 neutrons
C) an atom with 8 protons and 8 neutrons - an atom with 7 protons and 8 neutrons
D) an atom with 7 protons and 6 neutrons - an atom with 6 protons and 6 neutrons
Answer: The correct answer is Option B.
Explanation:
Isotope is defined as the chemical specie which belong to the same element but differ in their molecular mass.
The isotopes have same atomic mass but differ in their mass numbers
Atomic number is defined as the number of protons or electrons that are present in a neutral atom.
Atomic number = number of protons = number of electrons
Mass number is defined as the sum of number of protons and neutrons that are present in an atom.
Mass number = Number of protons + Number of neutrons
Thus, isotopes of an element has same number of protons but they differ in the number of neutrons.
For Example: Chlorine has 2 isotopes,
Number of protons = 17
Number of neutrons = 35 - 17 = 18
Number of protons = 17
Number of neutrons = 37 - 17 = 20
Hence, the correct answer is Option B.
75 K and 500 kPa
2
150. Kand 500 kPa
3
300. Kand 50 kPa
4
600. K and 50 kPa
Submit Answer
600k as well as 50kPa since the pressure seems to be the lowest as well as the temperature is the greatest throughout this situation.
Under high temperatures and low pressures, actual gases behaved like ideal gases. such as the rule
Even though at high temperatures, the kinetic energy of such gas particles surpasses the intermolecular attractive forces, — in other words this same potential energy of something like the molecules (gaseous).
Thus the above answer i.e., "option 4" is right.

Answer: 21 sleps
Explanation:
Given information: The substance skvarnick can be traded for gold coins in units of sleps and not quibs. Thus we need to convert the units of quibs to sleps.
It is given that 9 sleps is eqaul to 6 quibs, 14 quibs = ____ sleps.
