Answer: IONIC EQUATION.

Explanation:

A chemical equation is defined as the form by which a chemical reaction is represented mathematically. These are written in the form of symbols and chemical formulas of reactants and products which are taking part in the chemical reaction. A chemical equation can be written in two forms, these include:

--> MOLECULAR EQUATION: in this type of equations, the compounds are written and represented in a molecular form. This is sometimes referred to as a balanced equation.

--> IONIC EQUATION: This is a type of chemical equation in which the electrolytes in aqueous solution are expressed as dissociated ions. A typical illustrated example is seen in the reaction between AgNO3(aq) and NaCl(aq) :

Ag+(aq) + NO3-(aq) + Na+(aq) + Cl-(aq) → AgCl(s) + Na+(aq) + NO3-(aq)

The (aq) written in the above equation signifies they are in aqueous solution.

Each unit of pH represents a change by a factor of 10. Thus in a pH of 5, there would be 100x the concentration of Hydrogen ions in solution.

The correct option would be 2.

One question for chem?? Image attached? please help ! :)

The only bond that involves the complete transfer of electrons is ionic bonding.

A metal that does not have much care for its electrons, such as Sodium, Na, is willing to give up its electron more freely. And an atom that really cares about having electrons might be a gas such as chlorine, Cl. The Chlorine atom takes the electron from Sodium, and then the newly formed ions of Na+ and Cl- bond because they have equal and opposite charges and opposites attract. NaCl is formed.

Hydrogen bonds aren’t actually real bonds (I know, the name is deceptive)

Covalent bonds involve the sharing of electrons.

I’m pretty sure metallic bonds is a made-up term.

If a gas at 25.0 °C occupies 3.60 liters at a pressure of 1.00 atm, what will be its

yKpoI14uk [10]

Answer:

1.44 L

Explanation:

If the temp does not change

P1V1 = P2V2

1 * 3.6 = 2.5 * V2

V2 = 1.44 L

Assuming all other conditions remain the same, which of the following will cause an object's density to increase?

Elanso [62]

Taking into account the definition of density, assuming all other conditions remain the same, increasing mass will cause an object's density to increase.

Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space. That is, density is a quantity referred to the amount of mass contained in a given volume.

Density is an intensive property since it does not vary with the amount of substance.

Since density is the relationship between the mass and the volume of a substance, its calculation is defined as the quotient between the mass of a body and the volume it occupies:

$density=\frac{mass}{volume}$

In the previous expression it can be observed that the density is inversely proportional to the volume: the smaller the volume occupied by a certain mass, the greater the density.

On the other hand, density is directly proportional to mass: the greater the mass, the greater the density.

Finally, assuming all other conditions remain the same, increasing mass will cause an object's density to increase.

Answer:

Option (2)

Explanation:

Since the amount of each sample is the same, we are looking for the metal with the greatest density, which is copper.
