Gold is known to be an element. The term that best describes 10-karat gold is that it is an homogeneous mixture.
- Gold as an element of often has an ideal state of purity where there contains nothing but gold atoms.
A heterogeneous mixture is known to be a mixture that cannot be chemically sound everytime. Gold jewelry is known to be a homogeneous mixture as it is always will look good and remain unchanged for a long time.
As good example of homogeneous products, e.g a 1-kilogram 24-karat gold bar has unique properties.

Answer:
The concentration of nitrate ion 
is 0.033 M.
Explanation:
1 mole of ![[Al^{3+}]](https://tex.z-dn.net/?f=%5BAl%5E%7B3%2B%7D%5D)
= 3 mole
Let ![[NO_{3}^{-}]](https://tex.z-dn.net/?f=%5BNO_%7B3%7D%5E%7B-%7D%5D)
= 3y
then according to above reaction,
= y
= 0.10 M (given)
= ?
3y = 0.10 M
y = 0.033 M
So ,concentration of = y = 0.033 M
Mass = that which causes and object to have inertia
Newton’s First Law= a special case of Galileo’s Law of Inertia
Impulse= force multiplied by time
Momentum= velocity multiplied by mass
Velocity= momentum/mass
Newton’s Second Law= the acceleration of a mass directly proportional to the force acting on it
The major drawback of fossil fuels is that they warm the planet i.e. they cause global warming.
The reaction typically gives off heat and light as well. The general equation for a complete combustion reaction is:
Fuel + O2 → CO2 + H2O + ENERGY

Disadvantages of Fossil fuels</h3>
The term "fossil fuels" refers to flammable organic geologic formations, including dead organic matter that has been buried hundreds of feet beneath sediment.
- Fossil fuel emissions include various oxides, such as carbon, nitrogen, and sulfate, which cause acid rain and harm the soil's fertility and water quality.
- Both coal and petroleum burning discharge a significant amount of pollutants into the atmosphere, contributing to pollution levels.
- Gases like carbon dioxide are released through the burning of fossil fuels, which aids in climate change.
