Answer:
All compounds form when atoms of different elements share or transfer electrons. Compounds in which electrons are transferred from one atom to another are called ionic compounds.
Explanation:
Because the positive and negative charges cancel out, an ionic compound is neutral in charge.
Name the following ionic compounds that contain transition metals. Use the periodic table provided
and a chart that lists the possible charges of transition metals, found here.
Cuci
copper(1) chloride
O
copper chloride
copper(ll) chloride
DONE
The correct name of the compound CuCl is copper I chloride.
An ionic compound is formed two atoms when one loose electrons and the other atoms gains those electrons. Ionic bonds are actually an ion pair, a pair of oppositely charged ions held together by electrostatic interaction. Transition metals are elements with incompletely filled d orbitals. Copper is a transition element.
The compound CuCl is named copper I chloride. We can see that the copper is in the +1 oxidation state in this compound hence the name.

where do the electrons that are excited by the energy in sunlight first come from?
Answer:
Pigments in the light-harvesting complex pass light energy to two special chlorophyll a molecules in the reaction center. The light excites an electron from the chlorophyll a pair, which passes to the primary electron acceptor. The excited electron must then be replaced.
Explanation:
During photosynthesis,the electrons that are excited by the energy in sunlight first come from chlorophyll pigment present in the leaves.
What is photosynthesis?It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy through the process of cellular respiration.
Some of the energy which is converted is stored in molecules of carbohydrates like sugar and starches which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.
The process begins with proteins absorbing light energy which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.

Answer:

The mass lost by the positive electron should equal the mass gained by the negative electrode suggest two reasons why the results were not expected.
Answer:
The gain in mass by the negative electrode is the same as the loss in mass by the positive electrode. So the copper deposited on the negative electrode must be the same copper ions that are lost from the positive electrode.
what is the name of an interaction that would form between two ions?
Answer:
Intermolecular forces: are the forces of attraction or repulsion which act between neighboring particles (atoms, molecules, or ions ).
The interaction that would form between the ions (opposite charged) is called the ion-ion interaction.
What is the ion-ion interaction?Ion-ion interactions are attraction forces between ions that are oppositely charged. They are also known as ionic bonds and are the forces that held together ionic compounds.
The oppositely charged ions floating around in a vacuum will be attracted toward each other, and the attraction will become stronger as they move closer. When they finally stay together and take a considerable amount of energy to separate them.
They produce an ion-pair, a new particle that has a positively and negatively charged surface. The clusters tend to develop because these ion pairs and free ions have strong connections and finally fall out of the gas state as a liquid or solid.
The attraction forces of ions with opposite charges are called ion-ion interactions. The ions with similar charges repel each other, whereas ions with opposite charges attract.

Calcium carbonate decomposes into calcium oxide and carbon dioxide when heated. Calculate the mass of carbon dioxide released when 300 g of calcium carbonate is heated.
Write a Balanced Equation for the decomposition
CaCO₃ → CaO + CO₂
Find Moles of CO₂ Produced
Since the mole ratio of CaCO₃ to CO₂ is 1 to 1,
the moles of CaCO₃ = moles of CO₂
moles of CaCO₃ = mass ÷ molar mass
= 300 g ÷ 100.087 g/mol
= 2.997 moles
∴ moles of CO₂ = 2.997 moles
Determine Mass of CO₂
Mass = moles × molar mass
= 2.997 mol × 44.01 g/mol
= 131.9 g
∴ when 300 g of calcium carbonate is decomposed, it produces 131.9 g of carbon dioxide.
