The relationship between the "absolute temperature" on the Kelvin scale and the Celsius temperature is given bv: T(K) = t(°C) + 273.15 t(°C) = T(K) + 273.15 T(K) = 5/8[4°C)] - 32 D) T(K) = 8/5[t(°C)] + 32
Answers
The correct formula for converting Celsius to Kelvin is T(K) = t(°C) + 273.15 and the reverse is t(°C) = T(K) - 273.15. The Kelvin scale, unlike Celsius and Fahrenheit scales, is an absolute temperature scale and starts from absolute zero.
The relationship between the absolute temperature on the Kelvin scale and the Celsius temperature is defined by a simple conversion formula: T(K) = t(°C) + 273.15. This formula expresses the temperature T in Kelvin as the temperature t in Celsius degrees plus 273.15. The reverse conversion, from Kelvin to Celsius, is represented by the formula: t(°C) = T(K) - 273.15. The other equations presented in the question appear to include irrelevant or incorrect elements and are not standard conversions between Celsius and Kelvin.
It's crucial to note that the Kelvin scale, unlike the Celsius and Fahrenheit scales, is an absolute temperature scale based on absolute zero, the theoretically lowest possible temperature. Therefore, there are no negative temperatures in Kelvin. This is one of the many reasons why it is used in scientific and engineering contexts.

We are given:
There are 3 conditions:
When ; the reaction is product favored.
When ; the reaction is reactant favored.
When ; the reaction is in equilibrium.
As, , the reaction will be favoring reactant side or the reaction must proceed in the reverse direction.
Hence, the reaction must proceed in the reverse direction.

3 moles O₂ -------------> 2 moles Al₂O₃
? moles O₂ --------------> 1.00 mole Al₂O3
O₂ = 1.00 * 3 / 2
O₂ = 3 / 2
= 1.5 moles of O₂
Molar mass O₂ = 32.0 g
1.5 * 32.0 = 48 g of O₂
hope this helps!
Grams of the gas can be estimated by multiplying the moles and the molar mass. To produce 1 mole of aluminum oxide, 48 gms of oxygen is required.
What is mass?
The mass of the substance is the product of the moles and the molar mass of the given substance.
The balanced chemical reaction is shown as:
4 Al (s) +3 O₂ (g) → 2 Al₂O₃ (s)
From the above reaction, it can be concluded that:
3 moles of oxygen = 2 moles of aluminum oxide
So, x moles of oxygen = 1.00 moles of aluminum oxide
x is calculated as:
x = 3 ÷ 2 = 1.5 moles
Mass of oxygen:
mass = moles × molar mass
= 1.5 × 32
= 48 gms
Therefore, 48 gms of oxygen is required to produce 1 mole of aluminum oxide.

a) Let's balance the chemical equation for the reaction between HCl and HNO3 to form NOCl, Cl2, and H2O:
First, write the unbalanced equation:
HCl + HNO3 → NOCl + Cl2 + H2O
Now, balance it step by step:
1. Balance the atoms other than hydrogen and oxygen:
HCl + HNO3 → NOCl + Cl2 + H2O
1 1 1
2. Balance the oxygen atoms by adding water (H2O):
HCl + HNO3 → NOCl + Cl2 + H2O
1 1 1 +1
3. Balance the hydrogen atoms by adding HCl on the left side:
HCl + HNO3 → NOCl + Cl2 + H2O
1 1 +1 1 +1
4. Balance the chlorine atoms by adding Cl2 on the left side:
HCl + HNO3 → NOCl + Cl2 + H2O
1 1 +1 1 +1
Now, the equation is balanced.
b) Let's balance the chemical equation for the reaction between CO and I2O5 to form CO2 and I2:

is a product of a condensation reaction.
Explanation:
In a condensation reaction, two molecules are combined to produced a large molecules along with removal of a water molecule.
For an example, let's consider aldol condensation reaction.
In aldol condensation reaction, an enolate anion reacts and combines with an aldehyde or ketone molecule follwed by dehydration. In that dehydration step , gets removed and an unsaturated carbonyl product is formed.
Usually, are produced as a by product of a decomposition reaction.
