Describe how the suspects used the chemicals found at the crime scene to make the copper coins look silver.
The chemicals found at the crime scene although not mentioned must be Sodium zincate.
Discussion:
An interesting demonstration to show plating and alloys is the conversion of copper coins to silver look-alike coins.
A 'copper' coin when dipped into a solution of sodium zincate in contact with zinc. The coin is plated with zinc and appears silver in colour.
This is a common chemistry classroom trick.

why the mixture of bromine and ethane is discoloured when left in the sun
Answer:
In the presence of UV light, ethane will react with bromine in a substitution reaction. UV light is the condition under which the reaction will occur so it is written above the arrow in the chemical equation. As the reaction proceeds, the intensity of the re-brown colour of the bromine water decreases.
Answer:
here ya go
Explanation:
combining bromine and ethane leads to a brown gas or liquid which is made of the elements. it is a gas at room temperature and does not affect human beings. there are many uses for bromine compounds but they are mainly used for the manufacturing of chlorine, fire retadants, water purification, graphy chemicals and pharmaceutcals. it is a naturally occurring element that can be found in animals such as sharks since they produce their own.
When a gas is collected over water, the partial pressure of water must be subtracted from the total pressure. If the total pressure was 761 mmHg and the pressure for water is 17.2 torr, what is the pressure due to the gas collected
Answer is: the partial pressure of the hydrogen 500 mmHg.
p(total) = 523.8 mmHg.
p(water) = 23.8 mmHg.
p(total) = m(water) + p(hydrogen).
p(hydrogen) = p(total) - p(water)..
p(hydrogen) = 523.8 mmHg - 23.8 mmHg.
p(hydrogen) = 500 mmHg.
mmHg or millimeter of mercury is a manometric unit of pressure.

Atoms are the smallest particle that make up living things, they are made up of subatomic particles; protons, neutrons and electrons. Of these the electrons and neutrons are in the nucleus and the protons orbit around the nucleus. Of the subatomic particles, the electrons have the largest mass and are negatively charged, the neutrons (negative charge) and protons (positively charged) both have a relative mass of 1. Atoms contain an equal number of protons and neutrons, so carry no overall charge. An element is a substance made up of only two types of atom. Elements can be found in the Periodic table of elements, they usually have two numbers next to the chemical symbol, the larger number is generally the atomic number, which represents the number of neutrons and the number of protons. The smaller number is the relative atomic mass which represents the number of electrons or neutrons. In order to calculate the number of neutrons, you minus the atomic number from the relative atomic mass.

is isopropyl alcohol the same as hydrogen peroxide
Answer:
Unlike isopropanol, hydrogen peroxide is not a type of alcohol. You might recognize its chemical formula, H2O2, as being similar to that of water (H2O). The difference is that hydrogen peroxide has two oxygen atoms instead of one. That one extra oxygen atom makes it a strong oxidizer.
Which of these figures correctly illustrates the nature of the bonding of h2o?.
H2O is composed of two hydrogen atoms and one oxygen atom. The central oxygen atom is sp3 hybridized.
H2O is composed of two hydrogen atoms and one oxygen atom. The oxygen atom is bonded to the two hydrogen atoms at a dihedral angle of 104°. There are two lone pairs on the oxygen atom. The molecule has a bent geometry.
The structure of H2O is shown in the image attached to this answer. The central oxygen atom is sp3 hybridized and the shape of the molecule is based on a tetrahedron owing to its electron pair geometry.

what is the mass of the product of 111.6g and 48g
Answer:
159.6
Explanation:
Due to the law of conservation of mass, mass is neither created nor destroyed in a chemical reaction. Hence, the mass of the product is the equivalent of the mass of the sum of the reactants.
Which ground-state atom has an electron configuration described by the following orbital diagram?.
Answer:
The energy of atomic orbitals increases as the principal quantum number, n, increases. In any atom with two or more electrons, the repulsion between the electrons makes energies of subshells with different values of I differ so that the energy of the orbitals increases within a shell in the order s< p <d<f. Figure 1 depicts how these two trends in increasing energy relate. The 1s orbital at the bottom of the diagram is the orbital with electrons of lowest energy. The energy increases as we move up to the 2s and then 2p, 3s, and 3p orbitals, showing that the increasing n value has more influence on energy than the increasing I value for small atoms. However, this pattern does not hold for larger atoms. The 3d orbital is higher in energy than the 4s orbital. Such overlaps continue to occur frequently as we move up the chart.

Answer:
Look at the screenshot below.
Those are your answers!
Good Luck.
Explanation:
The number of valence electrons for neutral atoms is the same as the number of the atom's main group.A periodic table element's column can be used to determine its main group number.For instance, carbon, which belongs to group 4, has four valence electrons.
Use the periodic table to identify the number of valence electrons available for bonding for each of the following elements?
This rule states that each group of elements has one valence electron, two valence electrons in group 2, three valence electrons in group 13, four valence electrons in group 14, and so on. C : Six electrons make up the atom of carbon: four valence (outermost shell) electrons in the 2s and 2p orbitals, and two inner shell (core) electrons in the 1s orbital. H : As the initial element, hydrogen has an electron configuration of 1s1.Its valence shell only contains one electron.The outermost electrons or those with the highest energy level are called valence electrons. N : The periodic table's Group 15 is headed by nitrogen, which has either 3 or 5 valence electrons. O : On the periodic table, column 6 contains oxygen (symbol O).Its valence electrons number six.To obtain an octet, two bonds must be created. Ci : If chlorine removes one of its seven valence electrons, it will have eight (an octet).When chlorine gains one electron, its electron configuration resembles that of argon.If chlorine had given up all seven of its valence electrons and sodium had taken them, the octet rule would have been met.To learn more about periodic table refer

More than 7,000 islands in the Philippines lack access to electricity, so after the sun goes down, light usually comes through kerosene lamps. While cheap, these fire hazards are bad for the environment and human health.
You are an entrepreneur and would like to suggest to the government of the Philippines a better solution to this problem. But to come up with the solution to this problem, you must first understand the nature of chemical bonding and factors that control the structure of compounds. You will study and understand natural materials behavior to build a very cheap and environmentally friendly lamp.
What material do you think can be a cheaper and better alternative to kerosene?
Question 2 options:
There is no better alternative to kerosene.
A material that contains ions, so it can conduct electricity.
A material that contains gas, as gases can conduct electricity.
A material having covalent boding.
Answer:
Question 1: What material do you think can be a cheaper and better alternative to kerosene?
Answer: Generic lamp oil can be used to replace kerosene in lamps. The cheaper lamp oil burns cleaner and has less odor than the more expensive kerosene.

Why does water freeze at a temperature lower than 0°c when salt is added to it.
Answer:
Salt molecules block water molecules from packing together when temperature is lowered. It then prevents them from becoming ice. More water molecules leave the solid phase than the ones entering the solid phase. Freezing point depression occurs when the freezing point of the liquid is lowered by addition of solute.
