The answer is Solar, Wind, Geothermal, Hydrogen, Tidal, Wave, Hydroelectric, Biomass Energy.
Answer:
43.93 g/mol
Explanation:
The mass of the gas before reaction = 52.1487 g
The mass of the gas after reaction = 52.1098 g
Mass of gas generated = 0.0389 g
Moles of the gas = 
The formula for the calculation of moles is shown below:
Thus,
Molar mass of the gas = 43.93 g/mol
For group 16 elements, the atomic radii increases down the group as a shell of electron is added on each time.
1)
a)
D = 0.79 g/cm³ m = 85.1 g
D = m / V
0.79 = 85.1 / V
V = 85.1 / 0.79 => 107.72 cm³
____________________________________________
b) D = m / V
0.79 = m / 125
m = 0.79 x 125 => 98.75 g

First, we need to find the amount of winks in an hour, to simplify it so we can answer easier. Since there are 60 minutes in an hour, we can multiply 5 by 60 to find the number of winks in an hour.
5*60=300
Now multiply 300 by 8.
300*8=2,400
She winks exactly 2,400 times per day.
Hope this helps!
