Answer:
Explanation:
Hello there!
In this case, since these problems about formulas, firstly require the determination of the empirical formula, assuming that the given percentages are masses, we can calculate the moles and mole ratio of oxygen to iron as shown below:
In such a way, by rounding to the first whole number we multiply by 8 and divide by 5 to obtain:
Whose molar mass is 159.69 g/mol and the mole ratio of the molecular to the empirical formula is:
479.1/159.69=3
Therefore, the molecular formulais:
Regards!
V1/T1 = V2 / T2
V1 = 3/4(1700) = 1275
T1 = 10 + 273.15 = 283.15
V2 = 1700
T2 = V2T1
T2 = (1700) (283.15) / 1275
T2 = 377.53 K
No,Biomass is organic material which has stored sunlight in the form of chemical energy. Biomass fuels include wood, wood waste, straw, manure, sugar cane, and many other byproducts from a variety of agricultural processes. Biomass is a renewable energy source because the energy it contains comes from the sun<span>.</span>
<span>It contains 6.02mc001-2 particles of a given substance</span>
Answer:
Maximum gravitational Force: 
Explanation:
The maximum gravitational force is achieved when the center of gravity are the closer they can be. For the spheres the center of gravity is at the center of it, so the closer this two centers of gravity can be is:
bowling ball radius + billiard ball radius = 0,128 m
The general equation for the magnitude of gravitational force is:
Solving for:
The result is:
