Answer:

53.7kPa

Explanation:

Given parameters:

Total pressure of the mixture  = 96.4kPa

partial pressure of hydrogen  = 13.4kPa

partial pressure of oxygen  = 29.3kPa

Unknown:

partial pressure of methane  = ?

Solution:

The total pressure of mixture is equal to the sum of their particles pressures;

 

   Partial pressure of methane  = 96.4kPa - (13.4kPa + 29.3kPa)

  Partial pressure of methane = 53.7kPa

How does an electron reach an excited state
quester [9]

When an electron quickly occupies an strength state increased than its ground state, it is in an excited state. An electron can end up excited if it is given greater energy, such as if it absorbs a photon, or packet of light, or collides with a close by atom or particle.

liberstina [14]

Answer:

At the end of meiosis, there are four cells, each with 23 chromosomes, for a total of 92 chromosomes split between the four cells.

Explanation:

During meiosis, a diploid cell  (46 chromosomes) replicates its DNA (making 92 chromosomes) then undergoes two cell divisions to generate four haploid cells (23 chromosomes).

These haploid cells are the gametes which, during fertilization, fuse to become a zygote with 46 chromosomes.
