Answer:
No of moles = mass in gram / molar mass
Mass in gram = no of moles× molar mass
Mass in gram = 0.6330× 163.94
103.77 gram
Explanation:
Answer:
A. Plants
Explanation:
Plants are producers, which make their own food. Other organisms, such as rodents, birds, and wild cats, are consumers, which receive their energy from plants or other consumers.
Answer:
The standard entropy or reaction ΔS° =+324.6J/mol.K
Explanation:
The reaction is
2H2O(l) → 2H2(g) + O2(g)
Standard Molar Entropies of Selected Substances at 298 K are
Substance S∘ (J/mol⋅K)
H2(g) 130.6
O2(g) 205.0
H2O(g) 188.8
H2O(l) 69.9
The standard entropy of reaction will be obtained from standard entropy of formation as given below
ΔH°= 2(130.6)+(205.0)-2(69.9) (Jol/mol.K)
ΔH°=261.2+205.0-139.8
ΔH°=+324.6Jol/mol.K
Some common examples of Radiation are Ultraviolet light from the sun, heat from a stove burner, visible light from a candle, x-rays from an x-ray machine. ... This form of energy transfer is the radiation of heat. Our sun is the major source of heat energy.
