Answers
Answer:
Solvus: A solvus is a line or surface on a phase diagram which separates a homogeneous solid solution from a field of several phases which may form by exsolution or incongruent melting.
Eutectic: Relating to or denoting a mixture of substances that melts and freezes at a single temperature that is lower than the melting points of the separate constituents or of any other mixture of them.
Eutectoid: relating to or denoting an alloy which has a minimum transformation temperature between a solid solution and a simple mixture of metals.
Peritectic: A peritectic reaction is a reaction where a solid phase and liquid phase will together form a second solid phase at a particular temperature and composition.

e. How many grams of chlorophenol are there in 1.00 litre of a 47.0 mM solution? Show your calculations
in full.
(6 marks)
Answers
The mass of the chlorophenol is obtained from the number of moles and the volume of the solution.
Recal that;
Number of moles = concentration of solution * volume of solution
Concentration = 47.0 mM or 47.0 * 10^-3 M
Volume = 1.00 litre
Number of moles = 47.0 * 10^-3 M * 1.00 litre
Number of moles = 47.0 * 10^-3 moles
Also;
Number of moles = mass/molar mass
mass = Number of moles * molar mass
Mass = 47.0 * 10^-3 moles * 128.6 g/mol
https://brainly.com/question/9743981

Is the covalent bond BH2CL a polar nonpolar or ionic compound
Answers
BH2Cl is a polar compound because the molecule is non-symmetrical.
An ionic bond is usually formed between atoms having a high magnitude of electronegativity difference between them while covalent molecules tend to have a narrower range of electronegativity difference between atoms in the molecule.
In-between the two extremes are the polar covalent bonds which result from a significant electronegativity difference but less than that required for an ionic bond.
The B-Cl bond in BH2Cl is polar and the entire molecule is non-symmetrical hence the BH2Cl is a polar compound.

Which has higher specific heat capacity, iron or brick (Concrete
Answers
Answer:
Brick
Explanation:
Answer:
Explanation:
Brick has a heat capacity of 840 J/kg degree Centigrade.
That means that if you have 1 kg of brick, you will need to add 840 joules of heat to get it to go up 1 degree C.
The heat capacity of iron is 450 J/kg (degree centigrade).
Brick has the higher heat capacity. Undefined in all of this is a joule. It is a work unit. The problem is that to define a joule accurately, you need to bring in a lot of other units. Content yourself by understanding that both the iron and the brick are measured in the same units -- Joules.

Answer:
In redox reactions, electrons are transferred from one species to another. If the reaction is spontaneous, energy is released, which can then be used to do useful work. To harness this energy, the reaction must be split into two separate half reactions: the oxidation and reduction reactions. The reactions are put into two different containers and a wire is used to drive the electrons from one side to the other. In doing so, a Voltaic/ Galvanic Cell is created.
Explanation:
When a redox reaction takes place, electrons are transferred from one species to the other. If the reaction is spontaneous, energy is released, which can be used to do work. Consider the reaction of a solid copper (Cu(s)) in a silver nitrate solution (AgNO3(s)).
he AgNO3(s) dissociates in water to produce Ag+(aq) ions and NO−3(aq) ions. The NO3-(aq) ions can be ignored since they are spectator ions and do not participate in the reaction. In this reaction, a copper electrode is placed into a solution containing silver ions. The Ag+(aq) will readily oxidize Cu(s) resulting in Cu2+(aq), while reducing itself to Ag(s).
This reaction releases energy. When the copper electrode solid is placed directly into a silver nitrate solution, however, the energy is lost as heat and cannot be used to do work. In order to harness this energy and use it do useful work, we must split the reaction into two separate half reactions; The oxidation and reduction reactions. A wire connects the two reactions and allows electrons to flow from one side to the other. In doing so, we have created a Voltaic/ Galvanic Cell.
The kinetic energy of an object depends on how much space an object takes up True or false?

The first ionization energy of Mg is 735 kJ/mol. The second ionization energy is Select one: a. 735 kJ/mol b. less than 735 kJ/mol c. greater than 735 kJ/mol d. More information is needed to answer this question. e. None of these.
Answers
Taking into account the definition of ionization energy, the correct answer is option c: greater than 735 kJ/mol.
Electrons are held in atoms by their attraction to the nucleus, which means that energy is needed to remove an electron from the atom.
Ionization energy, also called ionization potential, is the necessary energy that must be supplied to a neutral, gaseous, ground-state atom to remove an electron from an atom. When an electron is removed from a neutral atom, a cation with a charge equal to +1 is formed.
The further away the electron is from the nucleus, the easier it is to remove it, that is, the less energy is needed.
The second ionization energy represents the energy required to start a second electron. Its value is always greater than the first ionization energy because the volume of a positive ion is less than that of the neutral atom and the electrostatic force is greater in the positive ion than in the atom.
In other words, the energy required to remove a second electron is called the second ionization energy, and due to the difficulty of removing an electron from a positive particle, its value is greater than that of the first ionization energy.
Finally, the correct answer is option c: greater than 735 kJ/mol.

Answers
Chemists prefer ribbon diagrams because they make the tertiary structure of the protein molecule easier to trace.
A protein molecule can be represented using several kinds of models. The ball and stick models which are common representations for other molecules can also be applied in the case of protein molecules.
However, the ribbon diagrams are preferred by chemists because they make the tertiary structure of the protein molecule easier to trace. Also, the ribbon diagram shows the overall path and organization of the protein backbone in the protein molecule.
This kind of structure was first introduced by Jane S. Richardson around 1981.

Ribbon diagrams look like the name they hold- ribbons. Therefore, they would be a good option if one were to trace or copy the diagram onto another document, etc. Also, they depict protein very well so if a chemist were studying different types of protein he/she would utilize a ribbon diagram.
