The maximum mass of magnesium used in its reaction with HCl is 0.08gm so the total pressure does not exceed 1.5 atm.

We will use ideal gas laws to solve this

For the final pressure, P = 1.5 atm

T= 298K

The equation of state for a synthetic perfect gas is known as the ideal gas law, sometimes known as the generic gas equation. Although it has significant drawbacks, it is a decent approximation of the behavior of many gases under various conditions.

Only an ideal gas or a real gas that behaves enough like an ideal gas can be approximated by the equation of state presented here (PV = nRT). The equation of state can be expressed in a wide variety of ways.

Let the moles of H, produced then

Using ideal gas law

P×V= n×R×T

Answer:

To calculate the kinetic energy of an object, we use the formula KE = 1/2 * m * v^2, where KE is the kinetic energy, m is the mass of the object, and v is the velocity of the object. In this case, the kinetic energy of the cart would be calculated as follows: KE = 1/2 * 800 kg * 10 m/s^2 = 4000 J.

Explanation:

However, it's important to note that the kinetic energy of an object depends not only on its mass and velocity, but also on its height. In the case of a cart moving down a slope, the potential energy it has due to its height will be converted into kinetic energy as it moves. Therefore, in order to accurately calculate the kinetic energy of the cart, we would need to know its height relative to some reference point (such as the ground), as well as its velocity.

a situation when opposing forces or actions are in equilibrium, whether that balance is static (such as when forces are applied to a body and the resultant is zero) or dynamic (such as in a chemical process that is reversible when the velocities in both directions are equal): a condition of mental or emotional equilibrium.

What is a simple definition of equilibrium in chemistry?

When the rates of the forward and backward reactions are identical, chemical equilibrium is reached. In other words, there is no net change in the reactant and product concentrations.

Equilibrium in chemicals is a dynamic process. Even after equilibrium has been attained, the forward and reverse reactions still happen. However, for a reaction that is at equilibrium, there is no change in the relative concentrations of reactants and products because the reaction rates are the same.

The reaction, though, continues unabated. Instead, the process reaches a state of chemical equilibrium where the forward reaction is producing products as quickly as the reverse reaction is converting reactants into products.

Calculate the half-life by using the formula as,

A(t) = I(0.5)^t/t1/2

Where t1/2 = half life = 1620

Final amount, A(t) = 0.55 of its original amount = 0.55I

Hence, we have

0.55I = I(0.5)^t/1620

Taking the log of both sides we get,

log(0.55) = log(0.5)^t/1620

t/1620 = log(0.55) / log(0.5)

t/1620 = 0.8624964

The equation for finding the mass of a system is:

mass = density x volume

where density is the mass per unit volume of a substance, and volume is the amount of space that a substance occupies.

To use this equation, you need to know the density and volume of the substance in question. For example, if you have a block of iron with a density of 7.8 g/cm^3 and a volume of 50 cm^3, you can find its mass using the equation above:

mass = density x volume

= 7.8 g/cm^3 x 50 cm^3

= 390 g

This means that the mass of the block of iron is 390 grams.

Thus, the rate of disappearance of O₂ is 0.37 mol L⁻¹ s⁻¹ , the rate of appearance of CO₂ is 0.2467 mol L⁻¹ s⁻¹

The rate at which a chemical reaction moves forward is known as the reaction rate in chemistry. It is frequently defined in terms of either the concentration of a reactant that is consumed in a unit of time or the concentration of a product that is generated in a unit of time (amount per unit volume).

The equation becomes:

C₂H₄(g) + 3O₂(g) → 2CO₂(g) + 2H₂O(g)

Rate of reaction = [tex]-\frac{d[C_2H_4]}{dt}[/tex] = [tex]-\frac{1}{3} \frac{d[O_2]}{dt}[/tex] = [tex]+\frac{1}{2} \frac{d[CO_2]}{dt}[/tex] = [tex]+\frac{1}{2} \frac{d[H_2O]}{dt}[/tex]

The term "temperature" refers to a measurement of an object's average kinetic energy, which is a category of energy linked to motion and used to describe how hot or cold an object is. But how hot and how frigid are they exactly? Hot and cool are not really scientific concepts. A physical scientist would check the metal's liquid state's temperature to find the answer. It is less confusing to use temperature instead of phrases like hot or cold.

The reaction's H is -6542 kJ as written. The heat produced by igniting 2 moles of C6H6(l) and producing 12 moles of CO2(g), for example, is represented by this.

We can determine moles of C6H6 combusted from the given mass of C6H6. We can then calculate the heat that would be produced based on that value. We can determine the change in water temperature after determining the amount of heat produced.

0.06785 moles are equal to 5.300 g C6H6 x 1 mol/78.11 g.

heat produced is equal to 221.9 kJ/0.06785 moles x 6542 kJ/2 moles.

q = mC∆T

Based on the nature of the acid as a triptotic acid, the molar mass of the acid is 247 g/mol.

What is a triprotic acid?

A triprotic acid is an acid which produces three moles of protons when dissolved in water.

The equation of the reaction at equivalence can be shown as follows;

H₃X + 3 NaOH ⇒ Na₃X + 3 H₃O

where X is the counter ion of the triprotic acid.

The ratio between the reacted acid and base at the third equivalence point = 1:3

The moles of substance reacted is calculated with the formula given below:

moles of substance reacted = molarity * volume

moles of NaOH reacted =  0.106M * 0.0352L = 0.003731 mole.

Thus, moles of H₃X reacted = 0.003731 moles /3

moles of H₃X reacted = 0.001244mole.

The molar mass of the acid can be calculated using the formula below:

molar mass =  mass /moles

molar mass of the acid = 0.307g / 0.001244mole

molar mass of acid = 247 g/mol

Therefore, the molar mass of the acid is 247 g/mol.
