Answer:
The correct option is methane :
.
Explanation:
Average speed of the gas molecules id given by expression:
k = Boltzmann cosnatnt
T = Temperature of the gas molecules = 355 K
m = molecular mass of the molecule
Molar mass of methane = 18 g/mol
Molar mass of neon = 20.18 g/mol
Molar mass of ethene = 28 g/mol
Molar mass of chlorine gas = 70 g/mol
Lower the value of molar mass of gas molecule higher will be the average speed.So, from the given options methane gas greatest average seed because it has lowest molecular mass
Answer: The correct answer is Heterogeneous mixture
Explanation:
Heterogeneous mixture are those mixture in which:
- Substance is distributed in non uniform manner.
- Two distinct layers are formed
Thus when water and dirt are mixed together it results in the formation of a heterogeneous mixture and after sometimes two different layers will be observed.
Hence, in the bottle there is a heterogeneous mixture of water and dirt.
Producer, Primary consumers, Secondary consumers and Tertiary consumers.
Stamen is not an outer covering its the reproductive organ of the plants.
<h3>What is use of covering of Plants ?</h3>
Outer covering of plants is useful in protecting them from environment factors , it is useful in keeping the moisture intact inside the plants.
Among the different outer covering , Bark ,stamen , spines and fuzzy hairs
Bark , stamen and fuzzy hairs are all the outer covering of plants
Stamen is not an outer covering its the reproductive organ of the plants.

Answer:
Simply put, you can go from moles to grams and vice versa by using the mass of 1 mole of that substance, i.e its molar mass. For example, the molar mass of carbon is 12.011 g/mol. This means that 1 mole of carbon, or 6.022⋅1023 atoms of carbon, weigh 12.011 g.
