Is sublimation of naphthalene a physical or chemical change?
A liquid evaporating is a physical change. Anything changing from a solid to a liquid (or liquid to solid), or from a liquid to gas (or gas to liquid) is a physical change).-Alec Vasquez
Why are the aqueous and the vitreous humors transparent?
They are transparent so that you can see through your eye. The aqueous humor is the small amount of liquid in your cornea that is sort of watery and the vitreous humor is the jelly like inside. They are not always transparent, sometimes there are small clumps of stuff in the vitreous humor called floaters, sometimes you can see them in your vision.
What are two kinds of changes that occur in matter?
The two types of changes in matter that it goes through is physical change and chemical change... trust me, we are learning this at school.
Is a solid changing from a liquid to a gas a physical or chemical change?
The change of a liquid to a gas is a physical change because its chemical properties do not change. Molecules of the liquid are just moving farther apart, therefore turning into a gaseous state.
What is the balanced equation for Liquid water is produced when hydrogen gas and oxygen gas combine?
H2o 2h2 + o2 = 2h2o
How does a chemical equation become aqueous?
A chemical equation represents a reaction that occurs in a liquid medium. When a chemical species dissolves and forms a solution with water, it is denoted by "(aq)" in the chemical equation. This indicates that the species is now in the aqueous state.
What are the 4 stae symbols of a chemical equation?
solid (s) gas (g) liquid (l) aqueous (aq)
What is the balanced equation for the dissociation of water?
The balanced equation for the dissociation of water is: 2H2O (liquid) ⇌ 2H+ (aqueous) + O2- (aqueous)
What is a different word for a chemical liquid?
aqueous
How do you write e the balanced chemical equation for reaction of aqueous hydrobromic acid reacts with aqueous sodium hydroxide to form liquid water and aqueous sodium bromide?
The balanced chemical equation for this reaction is 2HBr (aq) + 2NaOH (aq) → 2H2O (l) + 2NaBr (aq). This balanced equation represents the reaction between hydrobromic acid and sodium hydroxide to produce water and sodium bromide. Each side of the equation has the same number of atoms for each element.
What are the state symbols in a chemical equation?
State symbols in a chemical equation indicate the physical state of the reactants and products. Common state symbols include (s) for solid, (l) for liquid, (g) for gas, and (aq) for aqueous (dissolved in water).
What do each of the following abbreviations is often used in chemical equation represent?
(s) - solid (l) - liquid (g) - gas (aq) - aqueous (dissolved in water)
How do you determine phases in a chemical equation?
in a chemical equation after each element or compound of elements there is a ( ) which often has a letter in it such as (s) which is solid, (g) which is gas, (l) which is liquid. sometimes you will see an (aq) this means aqueous, or "dissolved in water"
Where do you place the symbols that represent the state of matter in an equation?
. After the chemical formula for each compound
How is the state of matter for a reactant or a product in a chemical equation indicated?
The state of matter for a reactant or product in a chemical equation is indicated by using symbols in parentheses next to the chemical formula. These symbols represent the physical state, such as (s) for solid, (l) for liquid, (g) for gas, and (aq) for aqueous (dissolved in water).
What are the 4 state equations of a chemical equations?
aqueous liquid gas solid
What are the 4 different phases used in chemical reations?
solid, liquid, gas, and aqueous
