Answer: Option (b) is the correct answer.
Explanation:
According to ideal gas law, the product of pressure and volume is equal to the product of number of moles, gas constant and temperature.
Mathematically, PV = nRT
So, when there are two gases with equal number of moles behaving ideally then the ideal gas equation will be as follows.
=
and =
Hence, when temperature and pressure of both the gases will be constant then = 1.
Thus, we can conclude that constant temperature and pressure is the conditions that must be met for a volume ratio to be created from a balanced chemical equation.
The formula for density is D=m/v, where m=mass and v=volume. So we can just do 890/100 and we end up with 8.90. The density of the copper is 8.90 grams per cm3

1. Mercury is the only metallic element that is liquid at standard conditions for temperature and pressure. 2. It is a poor conductor of heat, but a fair conductor of electricity. 3. Mercury does not react with most acids, such as dilute sulfuric acid, although oxidizing acids such as concentrated sulfuric acid and nitric acid or aqua regia dissolve it to give sulfate, nitrate, and chloride. 4. Mercury dissolves many other metals such as gold and silver to form amalgams. 5. It has a freezing point of −38.83 °C and a boiling point of 356.73 °C. Hope these 5 properties are enough :)

Answer:
the number of orange candies divided by total number of candies
the mass of orange candies divided by total mass of candies
Explanation:
<em>The two correct options that are appropriate to describe the concentration of orange candies would be </em><em>the number of orange candies divided by total number of candies </em><em>and </em><em>the mass of orange candies divided by total mass of candies.</em>
<u>The concentration of a substance can be described as the fraction of that substance in a particular mix of substances.</u>
In term of number, the concentration of a substance in a mix of substances can be expressed as the number of that substance divided by the total number of substances in the mix.
In term of mass, the concentration of a substance in a mix of substances can be expressed as the mass of that substance divided by the total mass of the mix.
