Answer:
An emulsion is a type of colloid formed by combining two liquids that normally don't mix.In an emulsion,one liquid contains a dispersion of the other liquid.Common examples of emulsion include egg yolk,butter etc.The process of mixing liquids to form an emulsion is called emulsification.
Answer:
Explanation:
In this case, we have to start with the <u>reagents</u>:
The compounds given by the problem are:
-) <u>Nitrogen gas</u> =
-) <u>Water vapor</u> =
-) <u>Aluminum oxide</u> =
Now, we can put the products in the <u>reaction</u>:
When we <u>balance</u> the reaction we will obtain:
Now, for the enthalpy change, we have to find the <u>standard enthalpy values</u>:
With this in mind, if we <u>multiply</u> the number of moles (in the balanced reaction) by the standard enthalpy value, we can calculate the energy of the <u>reagents</u>:
And the <u>products</u>:
Finally, for the total enthalpy we have to <u>subtract</u> products by reagents :

Answer:
1.626 M
Explanation:
Let's start by <u>calculating how many grams of C₂H₆O₂ are there per mL of solution</u>:
- 1 mL of solution weighs 1.40 g.
- 1.40 g of solution * =0.1008 g C₂H₆O₂
So the C₂H₆O₂ concentration can be expressed as 0.1008 g/mL.
Now we <u>convert g/mL to molarity</u>, using the <em>molar mass of C₂H₆O₂:</em>
- 0.1008 g C₂H₆O₂ ÷ 62 g/mol = 1.626x10⁻³ mol C₂H₆O₂
(1 mL = 0.001 L)
- 1.626x10⁻³ mol C₂H₆O₂ / 0.001 L = 1.626 M
