Explanation:
<u>Fahrenheit Scale
</u>
Fahrenheit temperature scale is the scale which is based on:
(a) For freezing point of the water, 32 °F.
(b) For boiling point of the water, 212 °F.
With interval between two being divided into equal 180 parts.
<u>
Celsius Scale
</u>
Celsius temperature scale is the scale which is based on:
(a) For freezing point of the water, 0 °C
(b) For boiling point of the water, 100 °C.
With interval between two being divided into equal 100 parts.
<u>Kelvin Scale
</u>
It denotes the triple point of water where the solid, liquid, and gas phases exist in equilibrium which is at 273.16 K.
kelvin is defined as 1/ 273.16 of triple point temperature.
Answer:
2. Option B.
Explanation:
H₂SO₄ + Ba(OH)₂ → BaSO₄ + 2H₂O
You can count 2H in sulfuric acid and 2 H in the barium hyrdoxide, so the coefficient for water must be 2.
You will have 4 H on both sides of the reaction.
Try with the dissociations of each reactant
Sulfuric acid ⇒ H₂SO₄ → 2H⁺ + SO₄⁻²
Barium hydroxide ⇒ Ba(OH)₂ → Ba²⁺ + 2OH⁻
Sulfate anion bonds to barium cation to produce the salt, therefore the 2 protons will bond the 2 hydroxide in order to produce, 2 moles of H₂O
2H⁺ + 2OH⁻ → 2H₂O
Answer:When you look at the periodic table, each row is called a period (Get it? Like PERIODic table.). All of the elements in a period have the same number of atomic orbitals. For example, every element in the top row (the first period) has one orbital for its electrons.
Explanation:
Answer:

Explanation:
We have the reactions:
A: 
B: 
Our <u>target reaction</u> is:

We have
as a reactive in the target reaction and
is present in A reaction but in the products side. So we have to<u> flip reaction A</u>.
A: 
Then if we add reactions A and B we can obtain the target reaction, so:
A: 
B: 
For the <u>final Kc value</u>, we have to keep in mind that when we have to <u>add chemical reactions</u> the total Kc value would be the <u>multiplication</u> of the Kc values in the previous reactions.
