According to the law of conservation of mass, the mass of the reactant must be equal to the mass of the product, hence the reaction is wrong
What is the conservation of mass?The law of conservation of mass states that mass within a closed system remains the same over time.
It states that the mass in an isolated system can neither be created nor be destroyed but can be transformed from one form to another.
Thus, the mass of the reactants must be equal to the mass of the products for a low energy thermodynamic process.
From the information given, we have the reaction written as;
HCI + NaOH → NaCl
The mass of the reactant Hydrogen(H) is not found on the product
The mass of the reactant(Oxygen) is also not found

Why is leaf called the kitchen of the plant?
Answers
Leaves of the plant contain a green colour pigment called chlorophyll. This pigment is responsible for trapping of sunlight which is essential for photosynthesis. This energy is used to synthesise food from carbon dioxide and water. Hence, leaves are called kitchen of the plant.
Plants rely on their leaves to produce food through a process called photosynthesis. This involves converting light energy into organic compounds, like sugars, using chloroplasts that contain the pigment chlorophyll. By combining carbon dioxide and water with light energy, plants create glucose, which serves as an energy source and building material. Along with stomata, which help regulate gas exchange with the environment, the leaf acts as the plant's primary kitchen for food production.

Answer:
Br-CH2-CH(CH3)2-C(Cl)H-CH(CH3)2-CHO
Explanation:
The molecule has a total of 14 carbon atoms, 13 hydrogen atoms, and 1 bromine atom. The carbon atoms are arranged in a chain with a methyl group attached to the second carbon atom, a chlorine atom attached to the third carbon atom, and two methyl groups attached to the fourth carbon atom. The fifth carbon atom has a carbonyl group attached to it.
The molecule is an aldehyde, which means that it has a carbonyl group (C=O) at the end of the chain. The carbonyl group is polar, and the oxygen atom has a partial negative charge. The hydrogen atom has a partial positive charge. This polarity makes the aldehyde group susceptible to nucleophilic attack.
The bromine and chlorine atoms are both electrophilic, which means that they have a partial positive charge. This makes them susceptible to nucleophilic attack.
The methyl groups are non-polar and do not have any significant reactivity.
The molecule is a chiral molecule, which means that it has a mirror image that is not superimposable on itself. This is because the carbon atom with the carbonyl group is attached to four different groups.
The molecule is a liquid at room temperature and has a strong odor. It is used in a variety of products, including perfumes, flavorings, and plastics.

Initially, a 400.3 m³ spring-loaded piston-cylinder assembly contains R-134a at 600 kPa and 150°C. The refrigerant temperature was cooled to -30°C and the volume was 0.1 m³. Calculate the transfer and the work produced by the refrigerant during this process.
Answers
ΔU = Q - W
We can assume that the process is quasi-static and reversible, so there is no entropy change (ΔS = 0). Therefore, the heat added to the system is simply the heat transfer (Q) and can be calculated using the specific heat capacity of R-134a at constant pressure (cp):
Q = m * cp * ΔT
where m is the mass of R-134a, cp is the specific heat capacity at constant pressure, and ΔT is the temperature change.
To calculate the work done by the refrigerant, we can use the following equation:
W = -P * ΔV
where P is the pressure and ΔV is the change in volume.
First, we need to find the initial and final states of the refrigerant:
State 1: P1 = 600 kPa, T1 = 150°C, V1 = 400.3 m³
State 2: P2 = 600 kPa, T2 = -30°C, V2 = 0.1 m³
We can use the R-134a tables to find the specific volume and specific internal energy at each state:
State 1: v1 = 0.1532 m³/kg, u1 = 783.1 kJ/kg
State 2: v2 = 0.0044 m³/kg, u2 = 131.3 kJ/kg
The mass of R-134a can be calculated from the initial volume and specific volume:
m = V1 / v1 = 400.3 m³ / 0.1532 m³/kg = 2614.4 kg
The heat transfer can be calculated as:
Q = m * cp * ΔT = m * cp * (T2 - T1) = 2614.4 kg * 1.14 kJ/kg·K * (-30°C - 150°C) = -573876.48 kJ
Note that the negative sign indicates that heat is being removed from the system (the refrigerant is being cooled).
The work done by the refrigerant can be calculated as:
W = -P * ΔV = P1 * (V1 - V2) = 600 kPa * (400.3 m³ - 0.1 m³) = 240120 J
Note that we converted the pressure from kPa to Pa and the volume from m³ to m³ to obtain the correct units for work (Joules).
Therefore, the transfer of heat from the refrigerant during this process is -573876.48 kJ, and the work produced by the refrigerant is 240120 J.

For the dissolution of HCl in water represented above, which of the following pairs includes the Brønsted-Lowry bases?
HCl(aq)+H2O(l)→H3O+(aq)+Cl−(aq)
Answers
By definition, the pair corresponding to the Brønsted-Lowry base is H₂O/H₃O⁺.
According to Brønsted-Lowry, acids and bases were defined in terms of the transfer of hydrogen ions, H+.
A compound that donates a proton to another compound is called a Brønsted-Lowry acid, and a compound that accepts a proton is called a Brønsted-Lowry base.
An acid-base reaction is, therefore, the transfer of a proton from a donor (acid) to an acceptor (base).
On the other hand, when an acid donates an H+, the resulting species is called the conjugate base of the acid because it reacts as a proton acceptor in the reverse reaction. Also, when a base accepts H+, it becomes its conjugated acid.
So, in this case, the pair corresponding to the Brønsted-Lowry base is H₂O/H₃O⁺.

What mass of oxygen is needed to burn 54.0 g of butane
Answers
Answer
The mass of oxygen needed to burn 54.0g of butane is 193.24 g
Explanation
Given:
Mass of butane = 54.0 g
What to find:
The mass of oxygen needed to burn 54.0g of butane.
Step-by-step solution:
Step 1: Write the balanced chemical equation for the reaction.
2C₄H₁₀ + 13O₂ → 8CO₂ + 10H₂O
Step 2: Convert 54.0 g of butane to moles
Molar mass of C₄H₁₀ = 58.12 g/mol
\(Moles=\frac{Mass}{Molar\text{ }mass}=\frac{54.0\text{ }g}{58.12\text{ }g\text{/}mol}=0.9291\text{ }mol\)Step 3: Use the mole ratio in step one and the mole of C₄H₁₀ in step 2 to calculate the mole of oxygen.
\(\begin{gathered} 13\text{ }mol\text{ }O_2=2\text{ }mol\text{ }C_4H_{10} \\ \\ x=0.9291\text{ }mol\text{ }C_4H_{10} \\ \\ x=\frac{0.9291\text{ }mol\text{ }C_4H_{10}}{2\text{ }mol\text{ }C_4H_{10}}\times13\text{ }mol\text{ }O_2 \\ \\ x=6.03915\text{ }mol\text{ }O_2 \end{gathered}\)Step 4: Convert the moles of O₂ in step 3 to mass in grams.
Molar mass of O₂ = 31.998 g/mol
\(\begin{gathered} Mass=Moles\times Molar\text{ }mass \\ \\ Mass=6.03915mol\times31.998g\text{/}mol \\ \\ Mass=193.24\text{ }g\text{ }of\text{ }O_2 \end{gathered}\)Hence, the mass of oxygen needed to burn 54.0g of butane is 193.24 g

Answers
Yes, the molarity in both the cases will be different if the indicator is changed from methyl orange to phenolphthalein or from phenolphthalein to methyl orange.
Since molarity is defined as the Molar concentration, also known as molarity, amount concentration, or substance concentration, is a unit used to describe the amount of a substance in a solution expressed as a percentage of the volume of the solution or it is the number of moles of solute divided by volume of solution in liters.
So on changing indicator, the number of moles changes as the molar mass is changing, so the molarity and other observations will get changed too and may increase or decrease.

At what temperature is the reaction at equilibrium?
A.157K
B.430K
C.0.002K
D.62K
Answers
Answer: B. 430 K
Explanation:
According to Gibb's equation:
\(\Delta G=\Delta H-T\Delta S\)
\(\Delta G\) = Gibbs free energy
\(\Delta H\) = enthalpy change = +62.4 kJ/mol
\(\Delta S\) = entropy change = +0.145 kJ/molK
T = temperature in Kelvin
\(\Delta G\) = +ve, reaction is non spontaneous
\(\Delta G\) = -ve, reaction is spontaneous
\(\Delta G\) = 0, reaction is in equilibrium
\(\Delta H-T\Delta S=0\) for reaction to be spontaneous
\(T=\frac{\Delta H}{\Delta S}\)
\(T=\frac{62.4kJ/mol}{0.145kJ/molK}=430K\)

From the particles shown, the ones that will have a stronger attraction to each other are those in water H₂O. This is because water has a boiling point of 100°C while that of CO₂ is -78.5. Hence, while both are covalently bonded, the bonds in water are stronger.
What is a Covalent Bond?It is to be noted that a covalent bond is formed between two atoms by the mutual use of one or more pairs of electrons. The two atomic nuclei attract these electrons at the same time. When the difference in electronegativities of two atoms is too tiny for electron transfer to produce ions, a covalent bond occurs.
The word "covalent bond" first appeared in 1939. The prefix co- denotes jointly, related in action, paired to a lesser degree, etc.; hence, a "co-valent bond" in essence indicates that the atoms share "valence," as defined in valence bond theory.

Why does CO2 have a higher boiling point than CH4 when they both possess dispersion forces?
Answers
CO₂ have a higher boiling point than CH₄ when they both possess dispersion forces because CO₂ consists of polar bonds between carbon and oxygen.
Intermolecular forces determine bulk properties, such as the melting points of solids and the boiling points of liquids.
Liquids boil when the molecules have enough thermal energy to overcome the intermolecular attractive forces that hold them together, thereby forming bubbles of vapor within the liquid.
CO₂ have a higher boiling point than CH₄ when they both possess dispersion forces because CO₂ consists of polar bonds between carbon and oxygen. The polarity increases the boiling point of the molecule.
