1. Can you light Diamond on fire?
2. What is the difference between a Chemical Process and a Physical Process?
3. How many electrons fit in each shell around an atom?
Answers
Answer:
a) Diamond can indeed be set on fire since it is made of carbon. ... Although diamond requires a higher temperature to burn, it does indeed burn via normal carbon combustion. You can even burn diamond in a regular flame if you are patient and conditions are right.
b) In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed. The distinction between physical and chemical change is not clear cut.
c) Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.

Mercury, which has 1/3 the gravity of
Earth?
A. more than on the Earth
B. less than on the Earth
C. the same as on earth
Answers
Answer:
The same as on earth
Explanation:
mass is the amount of matter in an object and the mass of an object is always the same at any point in time
gravity will only have effect on the weight and not the mass.
so assuming the question was talking about the weight, then we can say the weight will be lesser on Mercury

Answers
Answer:
a. friction
Explanation:
What is a common unbalanced force acting in motion? Common forces that are often unbalanced include the force of gravity and applied forces. When these forces are unbalanced, objects accelerate, change their position and find new configurations for which all forces are again balanced.
Friction is a kind of force.
Based on their definitions, electron affinity could be considered the opposite of
Answers
Based on their definitions, electron affinity could be considered the opposite of electron affinity. This is the force required to remove an electron from an atom while it is gaseous, or the propensity of an atom to lose electrons.
What is meant by electron?The electron is a subatomic particle with a negative one elementary charge electric charge. Due to their lack of components or substructure, electrons, which are part of the lepton particle family's first generation, are typically regarded to be elementary particles.
An electron is a negatively charged subatomic particle that can exist either free or bound to an atom (not bound). Along with protons and neutrons, electrons are one of the three primary types of particles that make up an atom. Together, protons, neutrons, and electrons make up the atom's nucleus.
This is the force required to remove an electron from an atom while it is gaseous, or the propensity of an atom to lose electrons. Conceptually, this is the polar opposite of electron affinity.

Yes, it has only a single covalent bond.
Explanation:
It has only a pair of electrons between the iodine atoms in order to gain a stable arrangement of 8 electrons in its outer shell. It is sharing them, so it's a covalent bond as a single iodine atom cannot be stable on its own. It's a halogen and is a single covalently-bonded diatomic molecule.

B. 00035416 g/cm^3
C. 354.16 g/cm^3
D. 3541.6 g/cm
Answers
Answer:
The answer is D.
Explanation:
Volume (V) = l x w x h
V = 4 x 5 x 1.2
V = 20 x 1.2
V = 24
Density = Mass/Volume or D = M/V
D = 85,000/24
D = 3541.66666666

The density of butter is 0.86 g/cm3. what is the mass of 240 cm3 of butter?
Answers
Answer:
mass= 206.4 g
Explanation:
Density= mass/volume
0.86=x/240
x=240×0.86
=206.4g
The density of butter is 0.86 g/cm³. 206.4g is the mass of 240 cm³ of butter. The phrase "specific volume" is occasionally used in thermodynamics to refer to a substance's reciprocal of its density.
Density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre. For example, the density of water is 1 gram per cubic centimetre, and Earth’s density is 5.51 grams per cubic centimetre. Density can also be expressed as kilograms per cubic metre (in metre-kilogram-second or SI units). For example, the density of air is 1.2 kilograms per cubic metre.
Density= mass/volume
0.86=x/240
x=240×0.86
=206.4g
