Answer:
Total we want 48 titanium to make 12.0moles
iron salts react with water to form hydrated iron ( III ) oxide which is basically rust
hope that helps :)
Answer:
Densities of the solids and the liquids are expressed in units of grams per cubic centimeter (g/cm³) or in grams per milliliter (g/mL).
Densities of the gases are usually expressed in the units of grams per liter (g/L).
Explanation:
Density of a substance can be defined as the ratio of its mass and its volume.
The constituting atoms in the solids and liquids are fairly packed closely together.
<u>In general, a 1 cm³ or 1 mL volume of most of the solids and the liquids has mass of several grams.</u> Thus, densities of the solids and the liquids are expressed in units of grams per cubic centimeter (g/cm³) or in grams per milliliter (g/mL).
The constituent atoms or the molecules in the gases are far apart from each other when compared to the solids and the liquids.
<u>Thus, gases are much less dense and even about 1 L of gas have mass in range close to 1 gram.</u> Thus, densities of the gases are usually expressed in the units of grams per liter (g/L).
<u>Also, the density of the gases also depend upon the pressure and the temperature but these factors much not influence the density of the solids and the gases.</u>
The new volume of the balloon : V₂ = 4.89 L
<h3>Further explanation</h3>
Given
V₁ = 4.96 L
T₁ = 6 + 273 = 279 K
T₂ = 2 + 273 = 275 K
Required
The new volume
Solution
Charles's Law
When the gas pressure is kept constant, the gas volume is proportional to the temperature
Input the value :
V₂=V₁.T₂/T₁
V₂ = 4.96 x 275 / 279
V₂ = 4.89 L
