Find the volume of a gas at STP, if its volume is 80.0 mL at 109 kPa and -12.5°C.​
exis [7]

Answer:

= 913.84 mL

Explanation:

Using the combined gas laws

P1V1/T1 = P2V2/T2

At standard temperature and pressure. the pressure is 10 kPa, while the temperature is 273 K.

V1 = 80.0 mL

P1 = 109 kPa

T1 = -12.5 + 273 = 260.5 K

P2 = 10 kPa

V2 = ?

T2 = 273 K

Therefore;

V2 = P1V1T2/P2T1

     = (109 kPa × 80 mL × 273 K)/(10 kPa× 260.5 K)

     <u>= 913.84 mL</u>

If an element has 3 valance electrons what row is it in?
klemol [59]

It can be any row

Explanation:

An element with a valence electrons of 3 can be in any row on the periodic table.

The rows are the horizontal arrangement of elements on the periodic table.

Elements on the same row have the same energy level.

  • The periodic table rows are called periods.
  • It is only in the groups that we can find such element.
  • Group 3 elements have 3 valence electrons.
  • Since this group cuts through all the rows, therefore, elements with 3 valence electrons can be found in any row.
