Which type of bond does the phrase “opposites attract” apply to best? Explain.
Answers
Answer:
The phrase "opposites attract" is true for atoms. The positively charged ion (cation) and the negatively charged ion (anion) are attracted to each other. It is this attraction, created by the transfer of electrons, that forms the ionic bond. The transfer of one electron creates a single bond.

It is this attraction, created by the transfer of electrons, that forms the ionic bond. The transfer of one electron creates a single bond.
Answer:
phrase opposites attract definitely describes ionic bond because this is the only type of bonds that requires positive charge in one atom and negative charge in other atom to form an ionic compound. HOPE THIS ANSWER YOUR QUESTION!!!

Answers
Answer:
A. Silver is a catalyst in this reaction.
Explanation:
The most common use of rare-earth metals is as catalysts in chemical reactions.
To solve such this we must know the concept of chemical reaction. Therefore, the correct option is option A that is Silver is a catalyst in this reaction.
What is chemical reaction?Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction.

The forces from below the surface that change the surface of the earth are
Erosion
Earthquakes
Volcanoes
Living things
Weathering
Faulting
Folding
Glaciers
Answers
Correct! The forces from below the surface that change the surface of the Earth include:
1. Erosion: The process of wearing away the Earth's surface by wind, water, ice, or other geological agents.2. Earthquakes: Sudden movements of the Earth's crust caused by the release of energy in the Earth's interior, resulting in shaking and sometimes surface displacement.3. Volcanoes: Openings in the Earth's crust through which molten rock, gases, and ash erupt onto the surface. Volcanic activity can lead to the formation of new landforms and alteration of existing ones.4. Weathering: The breakdown and alteration of rocks and minerals at or near the Earth's surface due to various physical, chemical, and biological processes.5. Faulting: The movement and displacement of rock layers along a fault line, typically caused by tectonic forces. This can result in the formation of new landforms or changes in the existing ones.6. Folding: The bending or warping of rock layers due to tectonic forces, resulting in the formation of folds and mountain ranges.7. Glaciers: Large masses of ice that slowly move over the Earth's surface, eroding the land and shaping the landscape through processes like plucking and abrasion.8. Living things: While not a direct force from below the surface, living organisms can play a role in shaping the Earth's surface through activities such as burrowing, root growth, and vegetation cover.These forces, both natural and influenced by living organisms, contribute to the continuous changes in the Earth's surface over time.

1. What is collision theory?
2. How does collision theory relate to factors that affect reaction rate?
3. Define reaction rate.
4. List factors that influence the rate of a chemical reaction.
5. Choose one of the factors you listed in your answer to question 2, and explain how it affects reaction rate.
Answers
Answer:
This is where google becomes your best friend but I got you
Explanation:
1. A theory used to predict the rates of chemical reactions, particularly for gases. The collision theory is based on the assumption that for a reaction to occur it is necessary for the reacting species (atoms or molecules) to come together or collide with one another.
2. Collision theory says that chemical reactions occur by the collisions between atoms and molecules, so the more collisions the faster the rate of the chemical reactions.
3. The speed at which a chemical reaction proceeds. It is often expressed in terms of either the concentration (amount per unit volume) of a product that is formed in a unit of time or the concentration of a reactant that is consumed in a unit of time.
4. There are four main factors that can affect the reaction rate of a chemical reaction:
Reactant concentration. Increasing the concentration of one or more reactants will often increase the rate of reaction. ...
Physical state of the reactants and surface area. ...
Temperature. ...
Presence of a catalyst.
Answer:
1. a theory that says a chemical reaction takes place when particles of the reactants collide with sufficient energy to initiate the reaction
2. Increasing the concentration of the reactants, the faster the particles will collide so the reaction rate will be faster
3. a measure of how fast a reaction takes place

Answers
Rocks expand and contract when they are heated and cooled which cause them to break. Physical weathering is experienced to the crust of earth. The last state of physical weathering is sand. Rocks that have some cracks are undergoing frost wedging.
What is weathering?Weathering is a geographical process of deterioration of rocks and minerals into parts and eventually into dust and sand. Thermal stress, a phenomenon caused by temperature variations, can also contribute to mechanical weathering.
The expansion and contraction of rock is influenced by temperature changes. The rock's structure deteriorates as this occurs repeatedly. Physical weathering and mechanical weathering disintegrates rocks without any chemical changes and it happens to the earth's crust.
Erosion of rocks eventually results in formation of sand. Frost wedging is a process by which ice erodes the rocks having cracks. It is also called ice wedging.

Which statement about exothermic reactions is true?
Responses
The reactants create energy to form products.
Energy from an outside source is continuously being added.
More heat is given off than is put into the reaction.
The reaction container always feels cold.
Answers
Answer:An exothermic reaction may be defined as a type of reaction in which energy is significantly liberated in the form of heat or light. In such types of reactions, energy is generally transferred into the surroundings rather than utilized from the surroundings.
The option "energy from an outside source is continuously being added" represents an endothermic reaction in which heat or light energy is externally been provided. The option "more heat is given off than is put into the reaction" is not absolutely true because exothermic reactions liberate energy but it does not matter if it is higher or lower than that of being put into the reaction.
Therefore, the reactants have more heat energy than the products is a statement that is true about exothermic reactions. Thus, the correct option for this question is C.
Explanation:
you welcome
Energy from outside sources is continuously being added, since its an exothermic reaction it always focusses on releasing large amount of energy upon activation and combustion.
It cuts off on giving energy back to its surrounding unlike endothermic reaction where the generated energy is given back to the environment to restore its energy levels.
Therefore, it makes it clear that exothermic reaction is a type of reaction that uses combustion to gather the energy lying around in the surrounding to generate large amount of energy and heat and keeps on producing heat until and unless there is energy in surrounding.
