Explanation:
The characteristics “fingerprints” of light produced when a substance is given energy are called…
A. Groundlings
B. Quantums
C. Spectrums
D. Amplitudes
A spectrum is a pattern is unique to a substance and can be used identify it.
According to Max Plank, energy occurs in packets called quanta. Hence, energy is not continuous but takes on discrete values which are integer multiples of a fundamental amount.
Again, when a substance is given light energy, a characteristic fingerprint is obtained. This pattern is unique to the substance that has it. These characteristics “fingerprints” are called spectrums.

Both graphite and pure metals are both soft. explain why
Answer:
In a pure metal, the force needed to make the layers slide over each other is small. This explains why many pure metals are soft. ... The smaller or bigger atoms distort the layers of atoms in the pure metal. This means that a greater force is required for the layers to slide over each other.

Select all the statements that correctly describe a solution. Multiple select question.
A. A solution is a mixture of substances dissolved in water.
B. A solution may have more than one solute.
C. Not all solutions are liquid.
D. A solution is a homogeneous mixture of two or more substances.
E. The solute is the substance present in the largest quantity.
Answer:
B, D, C
Explanation:
the solution may have more than one solute, a solution is a homogenous mixture of 2 or more substances and not all solutions are liquid
A solution is formed by the mixture of substances dissolved in water. There may have more than one solute. Not all solutions are liquid but there exists solid solutions too. Hence, options A, B, C are correct.
What are solutions?A solution is a combination of a solvent and a solid solute. The solute can be completely dissolved in the solvent and can have a partial solubility.
Water is a good solvent which dissolve majority of compounds. But there are other solvents too forming solution with suitable solutes. Solutions can be homogenous or heterogenous. Homogenous solutions are forming one phase and the solute particles are uniformly arranged.
Heterogeneous solutions are those where the solute particles are arranged in a non-uniformity and they form a different phase from the solvent.
There can be more than one solute in a solution provided that the solute can be of miscibility with each other.

is the transfer of heat from one object to another by direct contact. Which materials conduct heat most easily?
Answer:
Conduction is the transfer of heat between substances that are in direct contact with each other. Explanation:The better the conductor, the more rapidly heat will be transferred. Metal is a good conduction of heat. Conduction occurs when a substance is heated, particles will gain more energy, and vibrate more.

Answer:
Definition of crystal :- A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. Example of crystal :-large crystals include snowflakes, diamonds, and table salt.Meaning of crystal :-.
A piece of a homogeneous solid substance having a natural geometrically regular form with symmetrically arranged plane faces.

Explanation:
You want to manipulate each equation individually.
First Equation: Keep it how it is, because N2 is the same in the final and 1st equation
Second Equation: Multiply the enthalpy by 4 because you want the H2Os to be equal
Third Equation: Switch the sign of the enthalpy because you want toe H2O2 on the other side of the equation, and multiply by 2 to match the coefficient

Question 24 of 25
How can one tell if a reaction is a redox reaction?
O A. Elements change phases.
O B. A precipitate is formed.
O C. Spectator ions are present.
O D. Electrons are gained and lost.
Answer:
D. Electrons are gained and lost
Explanation:
When electrons are gain and lost, redox reaction takes place. In redox reaction, reduction and oxidation tales place simultaneously. Therefore, option D is correct.
What is redox reaction ?Redox reactions include a change in the oxidation state of the substrate. When electrons are lost or the oxidation state increases, it is called oxidation; when they are gained or the oxidation state decreases, it is called reduction.
Redox reactions are those in which there is a change in the oxidation number, with both an increase and a drop in number. The reaction called non-redox if this does not take place.
Oxidation and reduction always occur jointly because any loss of electrons by one substance must be followed by a gain of electrons by another. Therefore, oxidation-reduction processes or simply redox reactions are other names for electron-transfer events.
Thus, option D is correct.
