Answer: 362,07 cm3
To answer this question you need to convert the lb into gram first. One lb equal to 453.592g, so: 3.6lb x 453.592gram/lb= 1632.9312gram.
Now we have mass(1632.9312g), density (4.51g/cm3). Volume is mass divided by density. The equation would be:
Volume= mass/density
Volume = 1632.9312gram / (4.51g/cm3)= 362,07 cm3
I believe the correct answer from the choices listed above is option B. The best explanation for this happening would be that air <span>particles speed up and collide with the tire walls more often. As the particles are heated, kinetic energy increases. Hope this answers the question. Have a nice day.</span>
Answer:
Galena
Explanation:
Galena is also known as lead glance. This is a natural mineral of the form lead(II) sulfide. It is one of the most important ore for lead. It is widely found and is mainly distributed in sulfide minerals.
Galena can be easily scratched by finger nails. It has black streak and have a metallic luster. Galena have cleavage. It usually occurs as cubic crystals.
Explanation:
Start with a balanced equation.
2H2 + O2 → 2H2O
Assuming that H2 is in excess, multiply the given moles H2O by the mole ratio between O2 and H2O in the balanced equation so that moles H2O cancel.
5 mol H2O × (1 mol O2/2 mol H2O) = 2.5 mol O2
Answer: 2.5 mol O2 are needed to make 5 mol H2O, assuming H2 is in excess.
