True or false 4 questions help please!

Most mixtures are not physical changes.

True

False FALSE when I add solid NaCl salt to water I no longer have a solid salt, I have a solution of sodium and chlorid ions in liquid water. this is physical change

Chemical Changes do not create a new substance.

True

False FALSE 0ne of the proofs that you have a chemical change is the presence of a new substance

Fire is an example of a Chemical Change.

True TRUE fire is oxygen reacting wiIh mattter to form new compounds

False

Explosions are not chemical changes.

It depends on the explosion if I blow up a balloon until it POPS!! that is physical chame. If I light a firecracker and it explodes, that is a chemical change of oxygen reacting with hot gunpowder

A change in color and odor are both examples of chemical changi

I would rewrite the question as

A change in color and odor both INDICATE a chemical change

and that is

True TRUE

False

True Fire is an example of a Chemical Change.

True

False

Explosions are not chemical changes.

True

False

Solnce55 [7]

In a chemical reaction, matter can neither be created nor destroyed, so the products that come out of a reaction must equal the reactants that go into a reaction. Stoichiometry is the measure of the elements within a reaction.[1] It involves calculations that take into account the masses of reactants and products in a given chemical reaction. Stoichiometry is one half math, one half chemistry, and revolves around the one simple principle above - the principle that matter is never lost or gained during a reaction. The first step in solving any chemistry problem is to balance the equation.

Iron displaces copper from a solution of a copper salt.The reaction is deemed as a redox reaction. Give reason.

mel-nik [20]

When the iron is not bonded to anything the oxidation number is 0 but when it is bonded to a nonmetal it will be positive. All reactions in which the oxidation number changes are considered redox.

If gas is truly to be classified as a form of matter this means it can be measured. What form of gas can be measured?

juin [17]

Answer:

Gas is sometimes measured in cubic feet at a temperature of 60 degrees Fahrenheit and an atmospheric pressure of 14.7 pounds per square inch. Gas production from wells is discussed in terms of thousands or millions of cubic feet (Mcf and MMcf). Resources and reserves are calculated in trillions of cubic feet (Tcf).

Which change occurs when a barium atom loses two electrons?(1) It becomes a negative ion and its radius decreases.(2) It becomes

Tcecarenko [31]

<h2>Changes Occurs when a Barium Atom - Option 3 </h2>

When a barium atom loses two electrons it becomes a positive ion and its radius decreases. Barium (Ba) has atomic number 56 so it has 2 electrons in first shell of an atom to become stable according to duplet rule. Then other 52 electrons revolve in the shells according to octet rules.

Another 2 electrons are in the outermost shell. To become stable electrons lose to form barium ions (Ba+2). Hence, by losing 2 electrons the outermost shell will be diminished so its radius decreases and by losing electrons it becomes positive ions.
