How many moles of P2O3 are required to fully react with 108 H2O? (H2O; 18 g/mol)
P2O3 + 3H2O --> 2H3PO3
108 gH2O ---> mol P2O3
Answers
108 g H2O x (1 mol H2O / 18 g H2O) = 6 moles H2O
According to the balanced chemical equation, 3 moles of H2O react with 1 mole of P2O3 to produce 2 moles of H3PO3. Therefore, you need to divide the number of moles of H2O by 3 and multiply by 2 to get the number of moles of H3PO3 required:
6 moles H2O / 3 x 2 moles H3PO3 / 1 mole P2O3 = 4 moles P2O3
So, you would need 4 moles of P2O3 to fully react with 108 g of H2O.

In the above equation how many moles of N2 can be made when 13 moles of CuO are consumed?
Answers
Answer:
From 13 moles of CuO 4.3 moles of N₂ are formed
Explanation:
Given data:
Number of moles of N₂ formed = ?
Number of moles of CuO react = 13 mol
Solution:
Chemical equation:
2NH₃ + 3CuO → 3Cu + N₂ + 3H₂O
Now we will compare the moles of CuO and N₂.
CuO : N₂
3 : 1
13 : 1/3×13 = 4.3 mol
Thus, from 13 moles of CuO 4.3 moles of N₂ are formed.
From 13 moles of CuO 4.3 moles of N₂ are formed.
Given:
Number of moles of CuO react = 13 mol
To find:
Number of moles of N₂ formed = ?
The balanced chemical equation:
2NH₃ + 3CuO → 3Cu + N₂ + 3H₂O
On comparing the moles of CuO and N₂.
CuO : N₂
3 : 1
13 : 1/3*13 = 4.3 mol
Thus, from 13 moles of CuO 4.3 moles of N₂ are formed.

Calcite (the main mineral in limestone) is made of calcium carbonate (caco3). dolomite, a related mineral, is made of magnesium carbonate (mgco3). what happens if a geologist drips a small amount of vinegar (acetic acid) onto a sample of dolomite? there is no way to predict what will happen. fizzing will occur because carbon dioxide is produced. no reaction will occur because dolomite contains no calcium.
Answers
If a geologist drips a small amount of vinegar (acetic acid) onto a sample of dolomite, fizzing will occur because carbon dioxide is produced.
Why Carbon dioxide show effervescence?Effervescence observes whenever any gas tried to escape out from an aqueous solution, that's why CO₂ show effervescence.
Reaction between dolomite and acetic acid will be represented as:
MgCO₃ + 2CH₃COOH → CO₂ + H₂O + Mg(CH₃COO)₂
From the above reaction it is clear that carbon dixide gas is produced by showing the effervescence and fizzing behavior.

An investigation was carried out to see if the time taken for magnesium to react completely with hydrochloric acid was affected by the concentration of the acid used. Describe how students could tell when the reaction was complete at each concentration of acid.
Answers
Answer:
In an investigation to determine if the time taken for magnesium to react completely with hydrochloric acid is affected by the concentration of the acid used, students could tell when the reaction was complete by observing the reaction between the magnesium and the hydrochloric acid.
When the magnesium reacts with hydrochloric acid, hydrogen gas is produced as a byproduct. This reaction is exothermic, meaning it releases heat. As the reaction progresses, the magnesium will start to dissolve, and hydrogen gas bubbles will form and be released from the solution.
To determine when the reaction is complete at each concentration of acid, students can observe the reaction mixture and look for the following signs:
The magnesium ribbon stops fizzing: As the reaction progresses, the magnesium ribbon will start to dissolve, and hydrogen gas bubbles will be released from the solution. When the magnesium ribbon stops fizzing, it indicates that the reaction has slowed down significantly or has completely stopped.
The magnesium ribbon has completely disappeared: When the magnesium ribbon has completely dissolved in the hydrochloric acid, it indicates that the reaction is complete.
No more gas bubbles are being produced: As the reaction between magnesium and hydrochloric acid produces hydrogen gas, students can observe the reaction mixture to see if any more gas bubbles are being produced. When no more gas bubbles are being produced, it indicates that the reaction has completed.
By observing these signs, students can determine when the reaction is complete at each concentration of hydrochloric acid and accurately measure the time taken for the reaction to complete.

in an acetic acid/acetate buffer system, what will neutralize the addition of a strong base? a.) water b.) acetate c.) hydronium ion d.) acetic acid
Answers
Acetic acid will neutralize the addition of a strong base in an acetic acid/acetate buffer system.
In an acetic acid/acetate buffer system, the main purpose is to resist changes in pH when small amounts of acid or base are added. When a strong base is added, it increases the concentration of hydroxide ions (OH-) in the solution, which can shift the pH towards the basic side.
To neutralize the added strong base and maintain the buffer system, acetic acid (CH3COOH) acts as the main keyword. Acetic acid, being a weak acid, can react with the hydroxide ions (OH-) to form water (H2O) and acetate ions (CH3COO-). This reaction helps in counteracting the increase in hydroxide ions, thereby stabilizing the pH of the buffer system.
Water (H2O), acetate ions (CH3COO-), and hydronium ions (H3O+) are already present in the buffer system and do not actively neutralize the strong base. It is the addition of acetic acid that replenishes the buffer's acid component and maintains its pH buffering capacity.

In physical, energy are quantitative properties given to a body or physical system, perceivable in the form of work performance and heat and light. Energy is Conserved - The law of conservation of energy states that energy can be transformed into form, but cannot be created or destroyed. The unit of measure for energy in the International System of Units (SI) is the joule (J).
Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (due to its position in the field, etc.), the elastic energy stored by a fixed object, chemical energy, the energy associated with a chemical reaction, Includes radiation. is the energy transported by electromagnetic radiation and is the internal energy involved in a thermodynamic system. All living things absorb and emit energy all the time. Due to the equivalence of mass and energy, an object that has mass when it is at rest (called rest mass) has an equivalent amount of energy with a shape called rest energy plus an additional amount given to the object above that rest energy. It also has energy (in any form). Increases the object's total mass and increases its total energy.

Answers
a) Solubility in water: Take the square root of Ksp. b) Solubility in 0.10 M AgNO3: No significant change due to common ion effect. c) Solubility in 0.43 M K2SO4: Consider additional sulfate ions and calculate solubility using total concentration.
a) The solubility of silver sulfate in water can be calculated by taking the square root of the Ksp value.
b) The solubility of silver sulfate in 0.10 M AgNO3 will not change significantly because AgNO3 is a common ion and will already be present in high concentration.
c) The solubility of silver sulfate in 0.43 M K2SO4 can be calculated by considering the common ion effect. The concentration of sulfate ions from K2SO4 will increase the solubility of silver sulfate but will need to be accounted for in the calculation.
To calculate the solubility in each case, use the Ksp expression: Ksp = [Ag+]^2[SO4^2-].
For case a), take the square root of the Ksp value to find the solubility in water.
For case b), the solubility will remain similar to the solubility in water due to the common ion effect.
For case c), consider the additional sulfate ions from K2SO4. The total concentration of sulfate ions will be the sum of the initial sulfate concentration from Ag2SO4 and the added concentration from K2SO4. Use this total concentration to calculate the solubility of silver sulfate.

Answer:
14 grams of calcium oxide would be produced by thermal decomposition of 25 grams of calcium carbonate.
Explanation:
You know:
CaCO₃ → CaO + CO₂
In the first place, by stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction) the following quantities react and are produced:
CaCO₃: 1 moleCaO: 1 moleCO₂: 1 moleBeing:
Ca: 40 g/moleC: 12 g/moleO: 16 g/molethe molar mass of the compounds participating in the reaction is:
CaCO₃: 40 g/mole + 12 g/mole + 3*16 g/mole= 100 g/moleCaO: 40 g/mole + 16 g/mole= 56 g/moleCO₂: 12 g/mole + 2*16 g/mole= 44 g/moleThen, by stoichiometry of the reaction, the following mass amounts of the compounds participating in the reaction react and are produced:
CaCO₃: 1 mole* 100 g/mole= 100 gCaO: 1 mole* 56 g/mole= 56 gCO₂: 1 mole* 44 g/mole= 44 gYou can then apply the following rule of three: if by stoichiometry of the reaction 100 grams of calcium carbonate CaCO₃ produce 56 grams of calcium oxide CaO, 25 grams of CaCO₃ how much mass of CaO will it produce?
\(mass of calcium oxide=\frac{25 grams of CaCO_{3} *56 grams of CaO}{100 grams of CaCO_{3} }\)
mass of calcium oxide= 14 grams
14 grams of calcium oxide would be produced by thermal decomposition of 25 grams of calcium carbonate.
