A. There is very little empty space in a gas in not part of the kinetic molecular theory of gases.
Explanation:
The kinetic molecular theory of gases follows following points:
Kinetic energy does not change or get dissipated when gas molecules collide with each other. No attraction or repulsion between gas particles is observed. Particles of gas are moving randomly in all directions. Temperature increase cause the rapid movement of gas particles.The gas particles are placed very far from each other as compared to liquid.
The empty space in a gas is large because gas gets compressed in the small volume of the container also.
Answer
27.7 moles
Explanation:
Data Given:
Chemical formula of Calcium carbonate = CaCO₃
no. of atoms of CaCO₃ = 8.35 x 10²⁵ atoms
moles of CaCO₃= ?
Solution
First convert number of atoms to number of molecules
As
we have 5 atoms per molecule then how many molecules will be for 8.35 x 10²⁵ atoms
So, apply unity formula
5 atoms ≅ 1 molecule of CaCO₃
8.35 x 10²⁵ atoms ≅ X molecule of CaCO₃
by doing cross multiplication
X molecule of CaCO₃ = 8.35 x 10²⁵ atoms x 1 molecule / 5 atoms
X molecule of CaCO₃ = 1.67 x 10²⁵ molecule
Formula will be used
no. of moles = no. of molecules / Avogadro's number . . . . (1)
Where
Avogadro's number = 6.022 x 10²³ molecules/mol
So,
Put values in equation 1
no. of mole = 1.67 x 10²⁵/ 6.022 x 10²³ (molecules/mol)
no. of mole = 27.7 moles
So,
moles of CaCO₃ = 27.7 moles
A temperature regime that experiences consistent high temperatures with little seasonality is the <u>equatorial</u>.
<h3>What is temperature regime?</h3>
These systems have a significant impact on how soils are used and managed, especially when choosing plants that are adapted to the environment. There are 10 different soil temperature regimes: cryic, frigid, hyperthermic, isofrigid, isohyperthermic, isomesic, isothermic, mesic, pergelic, and thermic.
<h3>What is a mesic temperature regime?</h3>
Mesic. At a depth of 50 cm from the soil surface or at a dense, lithic, or paralytic contact, whichever is shallower, the difference between the mean summer and mean winter soil temperatures is greater than 6° C and the mean annual soil temperature is 8° C or higher but lower than 15° C.
