Answer:
c) oxygen
Explanation: In order for pea seeds to germinate, they require moisture. In order for cellular respiration to occur, oxygen is required.
According to Dalton's law of partial pressure
The total pressure of a mixture of ideal gases is sum of the partial pressures of each gas present in the mixture
So if we know the partial pressure of all the gases we can determine the total pressure of the mxiture by adding all of them.
Thus
Ptotal = PCl2 + PF2 + PHe
Thus
Partial pressure of helium = 205 - ( 89 + 15) = 101 kPa
<span>Following are important postulates of Kinetic theory of gases
1) Gases are made up of number of particles.
this particles behaves like hard and spherical objects, which are in constant state of motion.
2) The particles always travel in a straight line until they collide with another particle or the walls of the container.
3) Particles are of smaller size as compared to the distance between particles.
4) There exist minimal/no force of attraction between the gas particles neither there exist attractive interaction between the particles and the walls of the container.
5) Collisions between gas particles or with the walls of the container are elastic in nature.
Thus, statement a i.e. </span><span>Gas particles have a high force of attraction to one another or to the walls of the container contradicts the postulates of kinetic theory of gases</span>
Answer:
Damian here!! :))
The carbon family consists of the elements carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and flerovium (Fl). Atoms of elements in this group have four valence electrons. The carbon family is also known as the carbon group, group 14, or the tetrels. Elements in this family are of key importance for semiconductor technology.

Hope this helps? :))
