Answer:

its sodium hydroxide

Explanation:

To solve this problem, we need to use the concept of Avogadro's number and molecular weight.

The molecular weight of calcium carbonate (CaCO3) can be calculated as follows:

Now, we can calculate the number of molecules in 3.0 x 10^2 grams of CaCO3 as follows:

moles = mass / molecular weight

moles = 3.0 x 10^2 g / 100 g/mol

moles = 3.0 x 10^0 mol

number of molecules = moles x Avogadro's number

number of molecules = 3.0 x 10^0 mol x 6.02 x 10^23 molecules/mol

number of molecules = 1.806 x 10^24

Therefore, the answer is C) 1.81 x 10^24.

The energy of combustion for one mole of butane to be approximately 2888.81 kJ/mol.

To calculate the energy of combustion for one mole of butane (C4H10), we need to use the information provided and apply the principle of calorimetry.

First, we need to convert the mass of the butane sample from grams to moles. The molar mass of butane (C4H10) can be calculated as follows:

C: 12.01 g/mol

H: 1.01 g/mol

Molar mass of C4H10 = (12.01 * 4) + (1.01 * 10) = 58.12 g/mol

Next, we calculate the moles of butane in the sample:

moles of butane = mass of butane sample / molar mass of butane

moles of butane = 0.367 g / 58.12 g/mol ≈ 0.00631 mol

Now, we can calculate the heat released by the combustion of the butane sample using the equation:

q = C * ΔT

where q is the heat released, C is the heat capacity of the calorimeter, and ΔT is the change in temperature.

Given that the heat capacity of the bomb calorimeter is 2.36 kJ/°C and the change in temperature is 7.73 °C, we can substitute these values into the equation:

q = (2.36 kJ/°C) * 7.73 °C = 18.2078 kJ

Since the heat released by the combustion of the butane sample is equal to the heat absorbed by the calorimeter, we can equate this value to the energy of combustion for one mole of butane.

Energy of combustion for one mole of butane = q / moles of butane

Energy of combustion for one mole of butane = 18.2078 kJ / 0.00631 mol ≈ 2888.81 kJ/mol

Therefore, the energy of combustion for one mole of butane is approximately 2888.81 kJ/mol.

In conclusion, by applying the principles of calorimetry and using the given data, we have calculated the energy of combustion for one mole of butane to be approximately 2888.81 kJ/mol.

Answer:

The carbon fiber itself will withstand incredibly high temps. The weak point will be the epoxies or the resins.Ambient-cured epoxies will typically begin breaking down around 100 °C. The heat-cured epoxies that will go up to around 300 °C. As you get into the high temp ratings, the epoxies get trickier to handle, install, cure.Since the compositions of most irons while casting are around the eutectic point (lowest liquid point) of the iron–carbon system, the melting temperatures usually range from 1,150 to 1,200 °C.As is evident, at such high temperatures, the epoxies of Carbon Fibers will melt. So, they are not yet used for iron casting.

The average atomic mass of magnesium is 24.305 amu.

The mass of a single atom is too small to be measured directly, but chemists and physicists use the atomic mass unit (amu) to describe the mass of an atom.

The atomic mass unit is defined as 1/12th of the mass of a carbon-12 atom. Magnesium (Mg) has three isotopes: Mg-24, Mg-25, and Mg-26, with masses of 23.985 amu, 24.986 amu, and 25.983 amu, respectively.

These isotopes make up 78.99%, 10.00%, and 11.01%, respectively, of all naturally occurring Mg atoms.

The atomic mass of Mg can be calculated using the weighted average of the three isotopes as follows:Average atomic mass = (78.99/100 x 23.985 amu) + (10.00/100 x 24.986 amu) + (11.01/100 x 25.983 amu)Average atomic mass = 23.940 amu + 2.499 amu + 2.864 amuAverage atomic mass = 29.303 amu.

If heat is going into the system, then energy must have come out from the surroundings.

If heat is entering a system, it means that the system is gaining thermal energy, which can lead to an increase in temperature, changes in state, or other effects depending on the nature of the system and the heat transfer mechanism.

The first law of thermodynamics, also known as the law of conservation of energy, states that the total amount of energy in a closed system remains constant, and energy can neither be created nor destroyed, only transferred or converted from one form to another.

When heat enters a system, it is either used to increase the internal energy of the system or to perform work, such as moving a piston or driving an electrical generator.

The amount of heat transferred to a system can be quantified using the equation Q = mcΔT, where Q is the heat transferred, m is the mass of the substance, c is its specific heat capacity, and ΔT is the change in temperature.

Therefore, if the system is gaining energy in the form of heat, then the surroundings (the rest of the universe) must be losing that same amount of energy. This is because energy is conserved.

Answer:

the steady-state concentration of TCE in the treated water leaving the reactor is 5.88 mg/L  

Explanation:

Given that;

Tank volume v = 3250 liters

wastewater flows into the tank Q = 200 L/min

TCE concentration Co= 25 mg/L

reactor decays TCE at a reaction rate K = 0.20 min-1

mass balance

we know that;

Accumulation = inflow - outflow ± generation

⇒dc/dt = QCo - Qc ± rc.V

now at a steady state; dc/dt = 0

so

0 = QCo - Qc + rcV

where rc = -kc

0 = QCo - Qc - kcV

Qc + kcV = QCo

c(Q + kV) = QCo  

c = QCo / (Q + kV)

so we substitute

c = (200 × 25) / (200 + (0.2×3250))

c = 5000 / 850

c = 5.88 mg/L      

Therefore,  the steady-state concentration of TCE in the treated water leaving the reactor is 5.88 mg/L
