Which of the processes may possibly be isothermal?

Chemistry
1 answer:
Katena32 [7]2 years ago
6 0

In an isothermal process, the gas's work seems to be equal to the heat that is added to it. A constant temperature is employed for an isothermal process.

The first law of thermodynamic states that, Energy can only be changed in form; it cannot be created or destroyed, according to the basic law of thermodynamics. Any system can experience energy transfer when mass, heat, or external work cross the control border. These result in a change in the control volume's energy reserves.

Q= ΔU + W

where, Q is heat U is internal energy and W is work done.

In isothermal process, ΔU =0 , then.

Q=W

The process by which a gas stove converts chemical energy from energy resources into heat energy would be an illustration of the first law of thermodynamics.

Therefore, In an isothermal process, the gas's work seems to be equal to the heat that is added to it. A constant temperature is employed for an isothermal process.

Rutherford theorized that atoms have their charge concentrated in a very small nucleus.

This was famous Rutherford's Gold Foil Experiment: he bombarded thin foil of gold with positive alpha particles (helium atom particles, consist of two protons and two neutrons).  

Rutherford observed the deflection of alpha particles on the photographic film and notice that most of alpha particles passed straight through foil.

That is different from Plum Pudding model, because it shows that most of the atom is empty space.

According to Rutherford model of the atom:

1) Atoms have their charge concentrated in a very small nucleus.

2) Major space in an atom is empty.

3) Atoms nucleus is surrounded by negatively charged particles called electrons.  

4) An atom is electrically neutral.

How many grams of AlCl3 can be prepared from 3.5 moles of HCl gas?
poizon [28]

Answer:

156 g of AlCl₃ will be produced from 3.5 moles of HCl.

Explanation:

Given data:

Number of moles of HCl = 3.5 mol

Grams of AlCl₃ produced = ?

Solution:

Balanced Chemical equation:

3HCl + Al(OH)₃   →  AlCl₃ + 3H₂O

Now we will compare the moles of AlCl₃  with HCl from balanced chemical equation.

                   HCl          :           AlCl₃

                     3            :              1

                   3.5           :           1/3×3.5 = 1.17 mol

Mass of  AlCl₃ produced:

Mass = number of moles ×molar mass

Mass = 1.17 mol ×   133.341 g/mol

Mass =  156 g

Thus 156 g of AlCl₃ will be produced from 3.5 moles of HCl.

Compound Formula: C₆H₁₂O₆ what is the gram formula weight
PtichkaEL [24]
From the periodic table:
mass of carbon = 12 grams/mole
mass of hydrogen = 1 gram/mole
mass of oxygen = 16 grams/mole

The given compound C₆H₁₂O₆ has 6 moles of carbon, 12 moles of hydrogen and 6 moles of oxygen.
Therefore, the molar mass of the given compound will be calculated as follows:
molar mass = 6(12) + 12(1) + 6(16) = 180 grams/mole
