What are the ways that heat transfers? identify common examples of heat transfer.
Answers
Answer:
Conduction is the process of heat being transferred between objects through direct contact, and it's the most common type of heat transfer. For example, in cooking the burners on stoves will conduct heat energy to the bottom of a pan sitting on top of it. From there, the pan conducts heat to its contents.

what additional reaction product would result if naoh was used as a base in this reaction instead of k2co3?
Answers
Answer:
What reaction product would result if NaOH was used as a base in this reaction instead of K2CO3? If sodium hydroxide was used as the base of the reaction, then the reaction product formed would be an ethyl alcohol because it would undergo a hydrolysis reaction with addition of iodoethane
The entire carbonation reaction demonstrates how potassium carbonate (K2CO3) combines with water and carbon dioxide to create potassium bicarbonate (KHCO3) when exposed to combustion flue gases at low temperatures (40 to 80 °C) (Reaction 1)
What takes place when K2CO3 and water interact?In an extremely violent and exothermic reaction, potassium carbonate splits into potassium and carbonate ions when it interacts with water. When the ions interact, potassium oxide and carbonic acid are created.
K2CO3 come from : Potassium carbonate is a common ingredient in the manufacture of soap and glass. Additionally, it serves as a light drying agent. This substance is used as a buffering agent in numerous wine making procedures. Another usage for potassium carbonate is as a fire extinguisher.
K2CO3 created : Commercially, potassium carbonate is made by reacting potassium hydroxide with carbon dioxide:
2 KOH + CO2 = K2CO3 + H2.
K2CO332H2O sesquihydrate crystallizes from the solution ("potash hydrate").
The anhydrous salt is produced by heating this solid at 200 °C (392 °F).
It disintegrates into K2O+CO2 around 1200 C. (allreaction)
By converting carbonate into carbon dioxide and water, potassium carbonate can act as a base by forming potassium hydroxide.

Explanation:
negative ions form when atoms _______ valence electrons.
Answers
Answer:
Negatively charged ions are called anions, and an anion is formed when an atom gains an electron. Thus, the atom has an extra charge of electrons,
Explanation:
so it becomes negatively charged.
Negative ions (or anions) are atoms that have gained electrons.
Electrons have a negative charge so if an atom is getting more of them, it's becoming more negative.

There are 4 significant figures because when there is not a decimal, then only numerical values over 0 are counted. So the numbers counted in sig figs are 2049, and none of the other 0s.

The mass of the ice cubes will be greater because solids are more dense.
The mass of the ice cubes will be greater because they took up more space in the beaker.

The mass of the ice cubes and the water will be equal because the same amount of matter is in the beaker.
Matter is anything that has mass and occupy space. All substances are composed of matter. According to the law of conservation of mass, matter can neither be created nor destroyed but can be converted from one form to another.
Since mass is the quantity of matter in a substance, the mass of the ice cubes and the water will be equal because the same amount of matter is in the beaker.

Im doing a science project and need examples and non-examples of an Atom. some examples of an atom is neon, hydrogen, argon, etc so I got that part. But what are some non-examples of an atom and why?
Answers
Answer:
Anything not on the periodic table is an element non example! ... So, for a substance to be an element, all of its atoms must have the same number of protons. Examples of elements include hydrogen, lithium, nickel, and radium.
Explanation:
Non-examples of an atom refer to entities that are not considered atoms.
Molecules consist of two or more atoms chemically bonded together. They are not considered individual atoms because they contain multiple atoms connected by chemical bonds.
Ions are electrically charged particles formed when atoms gain or lose electrons. They can be positively charged (cations) or negatively charged (anions).
Subatomic particles are the constituents of atoms. They include protons, neutrons, and electrons.
Compounds are substances composed of two or more different elements chemically combined.

C.It can be drawn into long wires(ductility)
Answers
Answer:
A
Explanation:
Malleability describes the property of a metal's ability to be distorted below compression. It is a physical property of metals by which they can be hammered, shaped and rolled into a very thin sheet without rupturing. A soda can's walls are very thin, and therefore express the malleability of aluminum.
Which of the following has the most thermal energy?
A full-size candy bar that is melting
A swimming pool on a sunny day
The entire atmosphere of the earth
1 gallon of boiling water
Answers
The one that has the most thermal energy out of the following is 1 gallon of boiling water.
Thermal energy is the energy generated by a material as a result of particle movement inside the material. Thermal energy causes things to have an internal temperature, which may be measured. The greater the temperature measured, the quicker the particles travel within the system.
The full-size candy bar that is melting melts at a slower particle rate compared to the 1 gallon of boiling water whose particles travel faster.
A swimming pool on a sunny day has average thermal energy. Also, the entire atmosphere of the earth may not experience the same amount of thermal energy from the sunlight.
Therefore, we can conclude that the most thermal energy out of the following is 1 gallon of boiling water.
