6.4872 grams of H2O are present in 0.36 mol.

The molar mass of water (H2O) is 18.02 g/mol, which means that 1 mol of water has a mass of 18.02 grams. To find the mass of a certain number of moles of water, we can multiply the number of moles by the molar mass.

So, for 0.36 mol of water, the mass would be:

0.36 mol * 18.02 g/mol

= 6.4872 g

Therefore, 0.36 mol of water has a mass of 6.4872 grams.

The equation cp ≡ (∂h/∂t) at constant pressure defines the specific heat capacity at constant pressure, cp. This equation relates cp to the partial derivative of enthalpy, h, with respect to temperature, t, at constant pressure.

The specific heat capacity is a property that describes the amount of heat energy required to raise the temperature of a substance by a certain amount. When a substance obeys the perfect gas law, there is a simple relationship between the specific heat capacities at constant pressure (cp) and constant volume (cv), and the gas constant (R).

In the context of the perfect gas law, the enthalpy (h) is a thermodynamic property that represents the total energy of a system, including both the internal energy and the work done by the system. It is known that the enthalpy depends solely on the temperature (t) when other variables, such as pressure, are held constant.

By taking the partial derivative of enthalpy with respect to temperature at constant pressure (∂h/∂t)_p, we obtain the specific heat capacity at constant pressure, cp. This derivative represents how the enthalpy changes with temperature when pressure is held constant. It quantifies the amount of heat energy required to raise the temperature of a substance at constant pressure.

The equation cp ≡ (∂h/∂t)_p is derived from the definitions of cp and enthalpy, along with the perfect gas law and the knowledge that enthalpy depends only on temperature. It provides a direct relationship between the specific heat capacity at constant pressure and the partial derivative of enthalpy with respect to temperature at constant pressure.

Hydrazine is a chemical compound with the formula \(N_2H_4\). 120 molecules of\(NH_3\) will be formed if 60 molecules of \(N_2H_4\) decompose into \(N_2\) and \(NH_3\).

It is used as a rocket fuel and as a polymerization catalyst in the production of plastics and when hydrazine decomposes, it produces nitrogen gas (\(N_2\)) and ammonia (\(NH_3\)). If 60 molecules of hydrazine decompose into \(N_2\) and \(NH_3\), the number of molecules of \(NH_3\) that will be formed can be determined using the balanced equation for the reaction: \(N_2H_4 -- > N_2 + 2NH_3\). For every one molecule of hydrazine that decomposes, two molecules of ammonia are formed. Therefore, the number of ammonia molecules produced is twice the number of hydrazine molecules that decompose. Since 60 molecules of hydrazine are decomposing, the number of ammonia molecules formed is: 2 x 60 = 120 molecules of \(NH_3\)

0.154g of \(H2\) First, we'll begin by writing a balanced equation for the reaction between zinc (\(Zn\)) and hydrochloric acid (\(HCl\)). This is illustrated below:

\(Zn +2HCl — > ZnCl2 + H2\)

Next, let us determine the mass of Zn that reacted and the mass of H2 formed from the balanced equation.

This is illustrated below:

Molar Mass of Zn = 65g/mol

Molar Mass of H2 = 2x1 =2g/mol

From the balanced equation above,

65g of Zn produced 2g and H2.

Therefore, 5g of Zn will produce = (5 x 2) /65 = 0.154g of H2

From the calculations made above, 5g of Zn produced 0.154g of H2

When we study the behavior of gases, we usually assume that they are ideal gases, which means that they follow the ideal gas law, PV=nRT, perfectly.

However, not all gases behave like ideal gases in all conditions. The gases that exhibit non-ideal gas behavior are those that do not obey the ideal gas law, especially at high pressures and low temperatures. Some examples of such gases are carbon dioxide, water vapor, and ammonia. These gases tend to have stronger intermolecular forces, which make them deviate from the ideal gas behavior.

For instance, at high pressures, the volume occupied by the gas molecules becomes significant, and they start to interact more strongly, leading to lower compressibility and higher deviations from the ideal gas law.

Therefore, it is essential to consider the non-ideal gas behavior when studying the behavior of these gases in practical applications. In summary, carbon dioxide, water vapor, and ammonia are examples of gases that exhibit non-ideal gas behavior.

An ion is defined as an atom or a molecule which has a net electrical charge. There are 2 types of ions :1) cation 2) anion . The cation is the positively charged ion and anion is the negatively charged ion . As they are oppositely charged they attract each resulting in the formation of ionic bond.

Ions consisting of single atom are mono-atomic ions while which consists of two or more ions are called as poly-atomic ions . They are created by chemical interactions .

Explanation:

Answer:

The student's experiment represents a chemical change. Two reasons for this are:

Explanation:

- The formation of a blue solid indicates that a chemical reaction has occurred between the copper metal and the chlorine gas. The blue solid is likely to be copper chloride, which is formed when copper reacts with chlorine.

- The fact that the copper metal glowed red-hot also indicates that a chemical reaction occurred. When copper reacts with chlorine, energy is released in the form of heat and light. This is why the copper metal glowed red-hot during the reaction.

In summary, the formation of a new substance (copper chloride) and the release of energy in the form of heat and light are both indications that a chemical change occurred during the student's experiment.

The cooper metal's red-hot glow is yet another sign that a chemical occurred. Heat & light are both produced as a result of the action of copper and chlorine.  the copper metal lit up strongly during the reaction.

Copper oxidises to become copper. Copper is reduced to copper (I) oxides is heated in air, or the reddish brown metallic changes into black as it's oxidation to copper (II) ions. As a result, copper becomes copper oxide.

Copper () oxide, that is black in color, is produced as copper dust heat in a shallow tray combines with oxygen in the air. The corrosion of copper resulted inside the black color.

The pH of the solution is 1.60, by mixing 20.0 ml of 0.15 m hcl with 20.0 ml of 0.10 m koh.

pH = -log[H+]

Also;

mole of substance = molarity × volume in L

The moles of HCl = 0.15 × 0.02 = 0.003 moles

The moles of KOH = 0.10 × 0.02 = 0.002 moles

The solution will be acidic since the moles of HCl is greater than that of KOH.

Moles of remaining HCl [H⁺] remaining = 0.003 - 0.002 = 0.001 moles

Molarity of remaining HCl [H⁺] remaining = 0.001/0.04 = 0.025 M

Hence, [H⁺] = 0.025 M

pH = - log(0.025)
