<span>Begin by classifying which energy level, and indirectly principal quantum number, n, resembles to the N shell.
no. of orbitals =n2
In your case, the fourth energy level will contain
n=4⇒no. of orbitals= 4^2=16
The number of subshells is given by the principal quantum number.
no. of subshells=n
In your case, the fourth energy level will have
no. of subshells = 4 this is the answer
to check:
the fourth energy shell will can hold a thoroughgoing of no. of electrons=2⋅42=32 e−</span>
Answer:
132.94 kilo joules
Explanation:
We are given;
- Mass of benzene solution is 850 g
- Temperature change from 95°C to 3° C = 92° C or 92 K
We are required to determine the energy released by the cooling of benzene.
Taking the specific heat capacity of liquid benzene as 1.7 kJ/kg/K
Then we can determine the amount of heat energy released by using the formula;
Heat = Mass × specific heat × change in temperature
= 0.85 kg × 1.7 kJ/kg/K × 92 K
= 132.94 kilo joules
Therefore, the heat released by cooling benzene is 132.94 kilo joules
Answer:
672.6 grams
Explanation:
molar mass of 1 mol of C₈H₁₈ = 114 grams
so mass of 5.9mol of C₈H₁₈ = 114* 5.9= 672.6 grams
The cis double bonds give them an irregular shape
" formation of a gas" Is the answer you are looking for this is because the chemical change can happen without freezing melting or boiling a substance
