Answer:
4.22 g/mL
Explanation:
First we <u>calculate the mass of the solid</u> via <em>mass difference</em>:
- Mass of solid = 9.441 g - 1.005 g = 8.436 g
Then we <u>calculate the volume of the solid</u>, once again by difference:
- Volume of solid = 5.45 mL - 3.45 mL = 2.00 mL
Finally we <u>calculate the density in g/mL</u>:
- Density = 8.436 g / 2.00 mL = 4.22 g/mL
<span>Johannes Kepler, an apprentice of Brahe, believed in the heliocentric universe but rejected past astronomers' belief in "Circular Orbit Path." The circular orbit path refers to the path the planets in the solar system is following. It is believed before that it follows a circular path rather than an elliptical one.</span>

Answer: i)
ii)
iii)
iv)
v)
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The balanced chemical reactions will be:
i)
ii)
iii)
iv)
v)
