What is the value for AG at 100 Kif AH = 27 kJ/mol and AS = 0.09 kJ/(mol-K)?
A. AG = 2700 kJ/mol
B. AG = -36 kJ/mol
C. AG = 0 kJ/mol
D. AG = 18 kJ/mol
Answer:
ΔG = 18KJ/mol
Explanation:
Given data:
ΔG = ?
ΔS = 0.09 Kj/mol.K
ΔH = 27 KJ/mol
Temperature = 100 K
Solution:
Formula:
ΔG = ΔH - TΔS
ΔS = entropy
ΔH = enthalpy
by putting values,
ΔG = 27 KJ/mol - 100K(0.09 Kj/mol.K)
ΔG = 27 KJ/mol - 9 KJ/mol
ΔG = 18KJ/mol

Naming of compounds refers to the systematic process of assigning names to chemical compounds based on their composition and structure. It involves following certain rules and conventions to generate appropriate names that accurately represent the chemical formula and characteristics of the compound.
In inorganic chemistry, naming compounds often involves identifying the elements present and specifying their respective oxidation states or charges. Various naming conventions, such as the Stock system and the common system, are used depending on the type of compound and the specific elements involved.
Thus, the ideal selection is option C.

The oxidation # (charge) of an element called "lindenium "Ld is + 1 and the oxidation # (charge) of an element called "mendezine symbol "Mz, is -2. What is the chemical formula for the compound called lindenium mendezide?

General Formulas and Concepts:
Chemistry - Compounds
Valence shellsWriting chemical compoundsBalancing chargesExplanation:
Step 1: Define
"Lindenium" Ld w/ oxidation charge of +1
"Mendezine" Mz w/ oxidation charge of -2
Step 2: Write Compound
To balance out the charges to be neutral (0), we must counter balance the amount of Ld's with Mz's. We need 2 Ld's with 1 Mz to create a compound with a neutral charge:
2Ld¹⁺ + Mz²⁻
2(+1) + (-2) = (+2) + (-2) = 0 (neutral charge)
Therefore, our compound must be Ld₂Mz.

Aluminum nitrate reacts with sodium hydroxide to form a precipitate of aluminum hydroxide. What mass of aluminum hydroxide will precipitate when 35.5 mL of 0.145 mol/L aqueous aluminum nitrate is mixed with 44.2 mL of 0.215 mol/L aqueous sodium hydroxide?
Answer:
The mass of aluminum hydroxide that will precipitate when 35.5 mL of 0.145 mol/L aqueous aluminum nitrate is mixed with 44.2 mL of 0.215 mol/L aqueous sodium hydroxide is approximately 0.247 grams
Explanation:
The given parameters are;
The volume of 0.145 mol/L aqueous aluminum nitrate in the reaction = 35.5 mL
The volume of 0.215 mol/L aqueous sodium hydroxide in the reaction = 44.2 mL
The balanced chemical equation for the reaction is given as follows;
Al(NO₃)₃ (aq) + 3NaOH (aq) → Al(OH)₃ (s) + 3NaNO₃ (aq)
Therefore;
1 mole of Al(NO₃)₃, reacts with 3 moles of NaOH to form 1 mole Al(OH)₃, and 3 moles of NaNO₃
The number of moles of aqueous aluminum nitrate in the reaction = 35.5/1000 L × 0.145 mol/L = 0.0051475 moles
The number of moles of aqueous sodium hydroxide in the reaction = 44.2/1000 L × 0.215 mol/L = 0.009503 moles
Therefore, 0.009503 moles NaOH will react with 0.009503/3 moles Al(NO₃)₃ to form 0.009503/3 moles of aluminum hydroxide precipitate
The molar mass of aluminum hydroxide = 78 g/mol
Therefore, 0.009503/3 moles of aluminum hydroxide weighs 78 × 0.009503/3 = 0.247078 grams
The mass of aluminum hydroxide that will precipitate out ≈ 0.247 grams.
A gas has a volume of 1400 milliliters at a temperature of 20 K and a pressure of 760 mm Hg. What will be the
volume when the temperature is changed to 40 K and the pressure is changed to 380 mm Hg?
A. 350 mL
B. 750 mL
c. 1400 ml
D. 5600 mL
Answer: 1400 mL
Explanation:
The change in volume with change in pressure and change in temperature can be calculated using combination of gas laws. Here, the change in volume is 5600 ml.
What is combined gas laws?Boyle's law, Charles's law and Gay- Lussacs law all relating the temperature, pressure and volume of an ideal gas. The relation between these three parameters from the combination of these laws at conditions is written as:
P1 V1/T1 = P2 V2/ T2.
From this, the change in volume V2 can be calculated.
Given , P1 = 760 mmHg
T1 = 20 k and V1 = 1400 mL.
T2 = 40 k and P2 = 380 mmHg.
The new volume V2 = P1 V1 T2 / T1 P2.
= (760 mmHg × 1400 ml × 40K) / (20 K × 380 mmHg)
= 5600 mL.
Therefore, the change in volume of the gas is 5600 ml.

Answer: The first one would be a frozen thing like ice since the molecules are so packed, the next would be like this inside of a basketball or car tires, they move around freely(solid), and the last would be a gas since they aren't so many left(gas)
Explanation:
Matter are anything that is made up of atoms. The quantity of matter can be observed only on the basis of mass and volume calculation. Therefore, the states are solid, liquid and gases.
What is matter?Matter is a substance that has some mass and can occupy some volume. The matter is mainly used in science. Matter can be solid, liquid or gas.
Matter is anything that is made up of atoms. Anything around us that can be physically seen and touched are matter. Ice, water and water vapors are example of matter.
So as we saw that matter has some mass so mass can be measured in gram only. Mass can also be represented as number of molecules. We also saw that matter occupy some volume and that volume is measured only in liter. Degree of Celsius is used to measure temperature which has nothing to do with matter.
Therefore, the states are solid, liquid and gases.
