Good for you! : )
Explanation:
I don't know what happened but I am glad you are happy.
The mass of a present which has a density of 2.15 kg/L and volume of 3650 mL is 7.74 kg.
<h3>How do we calculate mass?</h3>
Mass of any substance will be calculate by using the density and volume by using the below equation as:
Density = Mass / Volume
Given that,
Density of Christmas present = 2.15 kg/L
Volume of present = 3,650 mL = 3.6L
On putting values, we get
Mass = (2.15)(3.6) = 7.74
Hence required mass of Christmas present is 7.74 kg.

Answer:
The root mean squared velocity for CF2Cl2 is 
Explanation:
From the question we are told that
The temperature is 
Root Mean Square velocity is mathematically represented as
Where T is the temperature
MW is the molecular weight of gas
R is the gas constant with a value of 
For CF2Cl2 its molecular weight is 0.121 kg/mol
Substituting values
The species which gives OH⁻ ion is known as Arrhenius base.
<h3>What are
Arrhenius bases?</h3>
Arrhenius bases are those species which are giving hydroxide ion (OH⁻) in an aqueous solution.
Properties of Arrhenius bases are:
- They are bitter in taste.
- Converts red litmus paper to blue color.
- Have pH value in the range of 7.1 to 14.
Examples of Arrhenius bases are sodium hydroxide (NaOH), potassium hydroxide (KOH), etc.
Hence, Arrhenius bases gives OH⁻ in an aqueous solution and NaOH is an example of this.
