Answer: CONDENSATION When steam is cooled, it releases thermal energy and turns into its liquid state. This process is called condensation. reversed if the liquid is cooled. The change from the liquid state to the solid state is called freezing
6. What is the equilibrium constant for the following reaction?
C+02 = CO2
Given
Reaction
C+02 = CO2
Required
The equilibrium constant
Solution
The equilibrium constant is the ratio of concentration or pressure between the product and the reactant with each reaction coefficient raised
The equilibrium constant is based on the concentration (Kc) in a reaction
pA + qB -----> mC + nD
[tex]\large {\boxed {\bold {Kc ~ = ~ \frac {[C] ^ m [D] ^ n} {[A] ^ p [B] ^ q}}}}[/tex]
So for the reaction :
C+O₂ ⇔ CO₂
[tex]\tt Kc=\dfrac{[CO_2]}{[C][O_2]}[/tex]
To convert between units, you need to know the relationship between units. For example, one mile equals 5280 feet. This relationship can now be used as a conversion factor, set up as required by the question. For each conversion, choose the correct arrangement of the conversion factor and complete the calculation 1. Convert 7860 feet to miles 7860 feet x (A)
A: 1 mile
B: 5280 feet 7860 feet miles 2. Co 0.5 miles to feet 0.565 miles x (C) TD
C: Choose...
D: Choose 0.565 miles feet
Answer:
1. 7860 Feet = 1.488 miles
A= 1
B= 5280
2. 0.565 miles = 2983.2 feet
C= 0.565
D= 1
Explanation:
1. Convert 7860 feet to miles
1 miles= 5280 feet
1 Feet= 1/ 5280 miles
7860 Feet= 7860 ( 1/ 5280) miles
7860 Feet = 1.488 miles
A= 1
B= 5280
2. Convert 0.565 miles to feet
1 mile= 5280 feet
0.565 miles = 5280 feet * (0.565/1)
0.565 miles = 2983.2 feet
C= 0.565
D= 1
We see that when we have to convert feet into miles we divide the number by 5280 because feet are smaller than miles. Similarly when we have to convert miles into feet we multiply by the given number because miles are greater than feet.
The above method used is called the unitary method but we should always keep in mind that conversion from smaller to bigger units require divsion and from bigger to smaller units require multiplication.
The following chemical reaction takes place in aqueous solution:
AgF(aq)+Nal(aq) ——> Agl(s)+NaF(aq)
Write the net ionic equation for this reaction.
The net ionic equation : Ag⁺(aq)+l⁻(aq) ⇒ Agl(s)
Further explanationGiven
Reaction
AgF(aq)+Nal(aq) ——> Agl(s)+NaF(aq)
Required
The net ionic equation
Solution
The equation of a chemical reaction can be expressed in the equation of the ions
In the ion equation, there is a spectator ion that is the ion that does not react because it is present before and after the reaction
When these ions are removed, the ionic equation is called the net ionic equation
AgF(aq)+Nal(aq) ——> Agl(s)+NaF(aq)
Ag⁺(aq)+F⁻(aq)+Na⁺(aq)+l⁻(aq) ⇒ Agl(s)+Na⁺(aq) + F⁻(aq)
Ag⁺(aq)+l⁻(aq) ⇒ Agl(s)

What is creating our Earth's Magnetic field?
1) Our Earth's iron liquid outer core rotating around the solid inner core
2) Our Earth having a stationary inner core
3) Our Earth having rocky center
4) All of the above
Answer:
1) Our Earth's iron liquid outer core rotating around the solid inner core
Explanation:
The earth's magnetic field or the geomagnetic field is produced as a result of the earth's iron liquid outer core rotating around the solid inner core.
This produces the earth's magnetic field.
The earth's core is made up of solid and liquid region. Only the densest elements are found within this region. So, the core is made up of metals which are mainly iron and nickel. The outer core is liquid or molten iron and the inner core is solid. The molten iron and nickel in the outer core moves around the inner core and generates the currents which induces a magnetic field round the earth.Which macromolecules break apart by hydrolysis?
Answer:
Dehydration synthesis reactions build molecules up and generally require energy, while hydrolysis reactions break molecules down and generally release energy. Carbohydrates, proteins, and nucleic acids are built up and broken down via these types of reactions, although the monomers involved are different in each case.
