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 reference ranges for blood potassium levels are as follows : Adult/elderly: 3.5-5.0 mEq/L or 3.5-5.0 mmol/L (SI units) Child: 3.4-4.7 mEq/L. Infant: 4.1-5.3 mEq/L.
Explanation:
Answer:A cell is the smallest unit of life, also called the 'building blocks of life' because cells multiply and differentiate to form a multicellular organism as well as give rise to new organism by forming gametes or reproductive spores.
Explanation:
Answer:o It is important to realise that mixing will be small unless there are electrons in the 4a1 LUMO, this is why NH3 is pyramidal while BH3 is planar! ... This mixing is very strong and stabilises the 3a1 MO substantially and hence NH3 is trigonal pyramidal and not planar.
