Answer:

Gas is the state of mater which changing its shape and volume according to the volume and shape of container.

Explanation:

Gas is the state of mater which changing its shape and volume according to the volume and shape of container.

Properties of gas:

Molecule of gases randomly move everywhere and occupy all available space.

Gases don't have definite volume and shape and take the shape and volume of container in which it present.

Their densities are very low as compared to the liquid and solids.

Gas molecules are at long distance from each other therefore by applying pressure gases can be compressed.

The very weak inter molecular forces are present between gas molecules.

A 1300 mL sample of gas with a molar mass of 71.0 g/mol at STP has what density?

Blizzard [7]

Answer:

0.055g/mL

Explanation:

Data obtained from the question include:

Molar Mass of the gass sample = 71g/mol

Volume of the gas sample = 1300 mL

Density =?

The density of a substance is simply mass per unit volume. It is represented mathematically as:

Density = Mass /volume.

With the above equation, we can easily obtain the density of sample of gas as illustrated below:

Density = 71g / 1300 mL

Density = 0.055g/mL

Therefore, the density of the gas sample is 0.055g/mL

Solid aluminum hydroxide reacts with a solution of hydrobromic acid. Write a balanced molecular equation and a balanced net ioni

lora16 [44]

Answer:

$Al(OH)_{3}(s)+3H^{+}(aq.)+3Br^{-}(aq.)\rightarrow Al^{3+}(aq.)+3Br^{-}(aq.)+3H_{2}O(l)$

$Al(OH)_{3}(s)+3H^{+}(aq.)\rightarrow Al^{3+}(aq.)+3H_{2}O(l)$

Explanation:

Aluminium hydroxide ( $Al(OH)_{3}$ ) is a base and hydrobromic acid (HBr) is a strong acid.

Hence an acid-base reaction occurs between $Al(OH)_{3}$ and HBr

Balanced molecular equation:

$Al(OH)_{3}(s)+3HBr(aq.)\rightarrow AlBr_{3}(aq.)+3H_{2}O(l)$

Balanced total ionic equation:

$Al(OH)_{3}(s)+3H^{+}(aq.)+3Br^{-}(aq.)\rightarrow Al^{3+}(aq.)+3Br^{-}(aq.)+3H_{2}O(l)$

Balanced net ionic equation:

$Al(OH)_{3}(s)+3H^{+}(aq.)\rightarrow Al^{3+}(aq.)+3H_{2}O(l)$

(net ionic equation is written by removing common ions present in both side of total ionic equation)
