When solid ammonium carbonate is heated, it decomposes to form ammonia gas, carbon dioxide gas, and water vapor, so that the solid completely disappears. Write a complete, balanced equation for this reaction.
Answers
Answer:
(NH4)2CO3(s) → 2 NH3(g) + CO2(g) + H2O(g)
Explanation:
The balanced equation can be written when we know the chemical formula of each reactants and products of the reaction.
Ammonium carbonate = (NH4)2CO3(s)
Ammonia = NH3(g)
carbondioxide = CO2(g)
water = H2O(g)
The ammonium carbonate was decomposed in the reaction , so ,
(NH4)2CO3(s) → NH3(g) + CO2(g) + H2O(g)
The reactant is on the left side while the product is on the right side. Let us balance the equation to make sure every atom of element is same number on both sides of the equation.
(NH4)2CO3(s) → 2 NH3(g) + CO2(g) + H2O(g)
Final answer:
The decomposition of ammonium carbonate upon heating produces ammonia, carbon dioxide, and water. The balanced equation for this decomposition reaction is: (NH4)(HCO3) → NH3 + CO2 + H2O.
Explanation:
The decomposition of solid ammonium carbonate (NH4)(HCO3) upon heating produces ammonia (NH3), carbon dioxide (CO2), and water (H2O) in gas form. This is a specific type of reaction called a decomposition reaction, which breaks down a compound into its constituent parts. The balanced chemical equation informing this process is: (NH4)(HCO3) → NH3 + CO2 + H2O.
Note from this equation, it is clear that the ammonium carbonate completely disappears as it gets converted into gaseous products upon heating.

Answer: ability to dissolve ionic substances
Explanation: Water is made up of hydrogen and oxygen molecules. The less electronegative hydrogen atoms occupy partial positive charge and oxygen being more electronegative occupy partial negative charge.
Due to this polarity, it is able to interact with ionic substances and thus dissolve them easily which is explained by the statement Like dissolves like. The ionic compounds are soluble in polar solvents and non ionic compounds are soluble in non polar solvents.
The ability to dissolve ionic substances is primarily due to the uneven distribution of charge between the hydrogen and oxygen atoms in water.
Water is a polar molecule, meaning it has a positive charge on one side (hydrogen) and a negative charge on the other side (oxygen). This polarity is a result of the unequal sharing of electrons between the hydrogen and oxygen atoms in the water molecule. The oxygen atom has a higher electronegativity than the hydrogen atoms, pulling the shared electrons closer to itself, resulting in a partial negative charge around the oxygen atom and a partial positive charge around the hydrogen atoms.
Because of its polarity, water molecules are attracted to ions in ionic substances. When an ionic compound, such as sodium chloride (NaCl), is added to water, the polar water molecules surround and separate the positive and negative ions, breaking the ionic bonds and causing the substance to dissolve. This ability of water to dissolve ionic substances is essential for various biological processes and makes it an excellent solvent for many substances.
In contrast, the other properties listed (color, taste, ability to produce buoyant forces) are not primarily related to the uneven charge distribution in water molecules but are influenced by other factors such as impurities, dissolved substances, and the reflection of light.

Answer: 9.13g NO
Explanation:
First, I list what I know, which is the values of STP, the volume, the constant R, and the molar mass of NO; I also include what I'm looking for, which is n, the number of moles of NO.
STP = 273.15K, 1 atm
P = 1 atm
V = 6.82L
R = 0.0821 L*atm/mol*K
T = 273.15K
n = ?
NO mass: 30.01 g/mol
Then, I use the ideal gas law, PV = nRT, to find the number of moles of NO:
(1 atm)(6.82 L) = n()(273.15K)
(1 atm)(6.82 L) = n()
(1 atm)(6.82 L) / () = n => divided both sides by 22.4L*atm/mol
n = 0.304 mol NO
Then, I use the molar mass of NO, 30.01 g/mol, to convert from mol NO to g NO:
g NO = 0.304 mol NO()
= 9.13 g NO
I hope this helps! :)
