Answer:

A. 0.641 L

Explanation:

<em>Given data:</em>

V1 = 2.5 L

T1 = 300.0 K

T2= 77.0 K

<em>To find: </em>

V2= ?

<em>Formula :</em>

By using Charles’ Law

\frac{V_1}{T_1}  = \frac{V_2}{T_2}

\frac{V_1}{T_1} . {T_2}  = {V_2}

<em>Calculation:</em>

V2 = 2.5 L x 77.0 K / 300.0 K

    = 192.5 / 300.0 k

V2    = 0.641 L

If the sentence is true, write true. If the sentence is false , replace the underlined word to make the sentence true.
ivann1987 [24]

1. False

Elements bond to form compounds.

Consider that compounds are essentially clumped up atoms. Knowing this, we know that atoms don’t separate, but rather combine in order to make compounds.

2. True

3. False

Atoms cam lose or gain electrons to form ionic bonds.

When at atom doesn’t have enough electrons to become stable, it will either give or take electrons from another atom in order to become stable. However, because of the fact that the atoms become oppositely charge, they attract each other, thus forming an ionic bond
