Answer:
<h3>The answer is 5.0 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 10 g
volume = 2 mL
We have
We have the final answer as
<h3>5.0 g/mL</h3>
Hope this helps you
Answer:
The rate of reaction rA is an intensive parameter.
Explanation:
The rate of reaction for a chemical species is typically -rA. Negative sign only shows that reactants are consumed when time is passing in the reaction.
Reaction rate will depend of several factors such as: Constant of equilibrium - K, Concentration of species - CA, Temperature - T and so on.
When we analyze the reaction rate the units are mol/Ls. It means that reaction rate will only depend of concentration and other variables. In this way, rate of reaction only is afected when we have changes in concentrations.
Concentration is an intensive parameter, it is not important if we have 100 kg or 100 L, or even 1 Kg or 1 L of total solution. Concentrations are the proportion of them and they will remain constant independent of the total mass or volume studied.
Due to the above, concentration and rate of reaction are intensive parameters and they do not depend of the total mass or volume studied.

Answer:
The carbon atom in CO2 has two double bonds, one with each atom of oxygen. Therefore, the carbon's hybridization is sp. Determine the hybridization for the other atoms in the molecule. Each oxygen atom in CO2 has a single double bond with the carbon.
