Answer:

1.52 L

Explanation:

P1V1T2=V2P2T1

V2=V1T2/T1

Fill in with given values then solve

We can check this by knowing that V and T at constant P have a proportional relationship. Hence, this is correct.

- Hope that helped! Please let me know if you need further explanation.

How much heat is required to change 25.0 g of water from solid to liquid at 0 oC? Water: ΔHfus = 334 J/g; ΔHvap= 2260J/g
xxMikexx [17]

Answer:

The heat required to change 25.0 g of water from solid ice to liquid water at 0°C  is 8350 J

Explanation:

The parameters given are

The temperature of the solid water = 0°C

The heat of fusion,   = 334 J/g

The heat of vaporization, = 2260 J/g

Mass of the solid water = 25.0 g

We note that the heat required to change a solid to a liquid is the heat of fusion, from which we have the formula for heat fusion is given as follows;

ΔH =  m ×

Therefore, we have;

ΔH =  25 g × 334 J/g = 8350 J

Which gives the heat required to change 25.0 g of water from solid ice to liquid water at 0°C  as 8350 J.

When a current is passed through a solution of salt water, sodium chloride decomposes according to the following reaction: NaCl
aivan3 [116]

Answer:

The answer to your question is   2NaCl  + 2H₂O    ⇒   2NaOH  +  Cl₂  +  H₂

Explanation:

Original chemical equation

                   NaCl  +  H₂O    ⇒   NaOH  +  Cl₂  +  H₂

                   Reactant      Element        Products

                       1                    Na                    1

                       1                    Cl                      2

                       2                    H                      3

                       1                     O                      1

This reactions is unbalanced

                2NaCl  + 2H₂O    ⇒   2NaOH  +  Cl₂  +  H₂

                   Reactant      Element        Products

                      2                    Na                    1

                      2                    Cl                     2

                      4                    H                      4

                      2                     O                     2

Now, the reaction is balanced
