Answer:
Here are a few more examples:
Smoke and fog (Smog)
Dirt and water (Mud)
Sand, water and gravel (Cement)
Water and salt (Sea water)
Potassium nitrate, sulfur, and carbon (Gunpowder)
Oxygen and water (Sea foam)
Petroleum, hydrocarbons, and fuel additives (Gasoline)
Heterogeneous mixtures possess different properties and compositions in various parts i.e. the properties are not uniform throughout the mixture.
Examples of Heterogeneous mixtures – air, oil, and water, etc.
Examples of Homogeneous mixtures – alloys, salt, and water, alcohol in water, etc.

Answer:
V₂ = 119.59 cm³
Explanation:
Given data:
Initial volume = 150 cm³
Initial temperature = 72°C
Final volume = ?
Final temperature = 2°C
Solution:
Initial temperature = 72°C (72 +273.15 K = 345.15 K)
Final temperature = 2°C (2 + 273.15 k = 275.15 K)
Solution:
According to the Charles Law.
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 150 cm³ × 275.15 K /345.15 K
V₂ = 41272.5 cm³.K / 298 K
V₂ = 119.59 cm³
Answer: D. 1600 L
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number
of particles.
To calculate the moles, we use the equation:


According to stoichiometry :
3 moles of
require 1 mole of
Thus 107.1 moles of
will require=
of
Thus
is the limiting reagent as it limits the formation of product and
is the excess reagent.
As 3 moles of
give = 2 moles of
Thus 107.1 moles of
give =
of
Volume of
Thus volume of ammonia produced is 1600 L
Answer:
The periodic table of elements arranges all of the known chemical elements in an informative array. Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass. The rows are called periods.
Explanation:
I don't think it's any of the above. Because there is two double carbon bonds and it belongs to an alkene, it should be an ethene molecule.
