Which of these scenarios involve a reaction that is at equilibrium? a. the reaction is producing reactants and products at an equal rate.
b. the reaction is producing more reactants than products.
c. the reaction is only producing products
d. the reaction is producing more products than reactants.

Answers

at equilibrium the reaction is producing reactants and product at an equal rate so option A is correct hope this helps

Answer:

a. the reaction is producing reactants and products at an equal rate. is the correct answer.

Explanation:

If a reaction is at equilibrium then the reaction rates for both the reverse and forward directions are equal.

catalyst that increases the reaction rate of a reaction, but it does not change the equilibrium state for that reaction.

Thus at the equilibrium stage, the concentration of the reactants and the product remain constant.

If one body is positively charged and another body is negatively charged, free electrons tend to A. move from the negatively charged body to the positively charged body.
B. remain in the negatively charged body.
C. move from the positively charged body to the negatively charged body.
D. remain in the positively charged body.

Answers

I think the correct answer is A. If one body is positively charged and another body is negatively charged, free electrons tend to move from the negatively charged body to the positively charged body. This happens because they have different charges and therefore electrons are more attracted to the positive or its opposite charge.

Answer:

A. move from the negatively charged body to the positively charged body.

Explanation:

because this is the correct answer

A bond exists between A and B in the compound AB. A and B are sharing electrons. The type of bond is ____

Answers

Answer: Covalent

Explanation:

A covalent bond is formed when an element shares its valence electron with another element. This bond is formed between two non metals. Example: $H_2$

An ionic bond is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element and the element which accepts the electrons is known as electronegative element. This bond is formed between a metal and an non-metal. Example: $NaCl$

Thus bond formed by sharing of electrons is covalent bond.

They are covalent bonds.
Covalend bonds share
Ionic bonds transfer

Why are some elements more reactive than others?

Answers

All other atoms have less stable electron numbers, so they react with each other and share electrons to be more stable. The most reactive elements tend to be short one or two electron or have one or two extra electrons.

The change of state from liquid to gas is called

Answers

When liquid surface particles transition into gas phase, evaporation occurs. The process of change of state from liquid to gas is called as evaporation.

What is evaporation ?

The process of evaporation turns liquid water into gaseous water (water vapor). Evaporation is how water gets from the surface of the Earth to the atmosphere. Heat energy causes the bonds holding the water molecules together to fall apart, which causes evaporation.

When liquid surface particles transition into gas phase, evaporation occurs. Only the liquid particles near the surface have enough energy to separate from the remainder of the liquid and exit into a gaseous phase, making it a surface phenomenon.

The water cycle includes evaporation, which is a crucial step. The evaporation process is driven by solar energy, or heat from the sun. It absorbs moisture from both the largest oceans and lakes as well as garden soil.

Thus, The change of state from liquid to gas is called as evaporation.

The change of state from liquid to gas is called evaporation because solid to liquid is called melting and liquid to solid is called freezing and solid to gas is called sublimation and gas to solid is called deposition. So liquid to gas is called evaporation......hope it helped :)
