A weather balloon containing helium with a volume of 410.0 L rises in the atmosphere and is cooled from 17∘
likoan [24]

Answer:

V₂ = 1500 Liters ( 2 sig. figs.)

Explanation:

Given the following gas law variables:

P₁ = 110.0KPa           P₂ = 25KPa

V₁ = 410 Liters          V₂ = ?

T₁ = 17°C ( = 290K)   T₂ = -27°C  ( = 248K)

P₁V₁/₁T₁ = P₂V₂/T₂  =>  V₂ = V₁(P₁/P₂)(T₂/T₂)

V₂ = 410L(110.0KPa/25KPa)(248k/290K) = 1542 L (calc. ans.)

V₂ = 1500 Liters ( 2 sig. figs.)

If solutions of nh4cl(aq) and nh3(aq) are mixed, which ions in the resulting solution are spectator ions in any acid-base chemis
Gwar [14]
If solutions of nh4cl(aq) and nh3(aq) are mixed, the ions in the resulting solution that would be the spectator ions in any acid-base chemistry occurring in the solution would be the chloride ions. The mixture is a common buffer of ammonia and ammonium chloride.  NH4Cl is a salt that is soluble in water dissociating into NH4+ and Cl-. The chloride ions are the spectator ions while NH4+ ions would be the conjugate acid for the buffer solution. Buffer solutions are solution which would resist change in pH when acid or a base is being added to the solution. The equilibrium reaction of the buffer solution in this problem would be

NH3 + H2O = OH– + NH4+

a gap in the rock layer due to erosion from no rocks being deposited.HELP FAST PLEASE!?!?!?!?
Allushta [10]

a gap in the rock layer due to erosion or from no rocks being deposited

geological processes taking place today are the same as those that occurred in the past.  

fossil that record the shape and structure of an organism

each layer is older than the layer above and younger than the layer below it.

the preserved remains or traces of a once living organism.

fossils that record the movement or behavior of an organism.

sediments spread in all directions until they thin out or hit a barrier.

sedimentary rocks are deposited horizontally.

age of rock compared to the ages of rock layers.

age of rocks calculated in years since formed.

words:

1.absolute age

2.body fossil

3.fossil

4.principle of lateral continuity

5.principle of original horizontally

6.principle of superposition

7.relative age
