A gas at 127 celsius and 10.0 L expands to 20.0 L. What is the new

Chemistry

Answer:

T₂ = 800 K

Explanation:

Given that,

Initial temperature of the gas, T₁ = 127°C = 400 K

Initial volume, V₁ = 10 L

Final volume, V₂ = 20 L

We need to find the new temperature.

The volume of a gas is directly proportional to its Kelvin temperature.

Let T₂ is the new temperature. So,

\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}\\\\T_2=\dfrac{V_2T_1}{V_1}\\\\T_2=\dfrac{20\times 400}{10}\\\\T_2=800\ K

So, the new temperature of the gas is 800 K.

Is it the power of material evidence that wins, not the authority of experts that
kvasek [131]

Yes, it is the power of material evidence that wins.

  • Evidence used to support or refute a scientific theory or hypothesis is known as material evidence.
  • Evidence is also used by scientists in various contexts, such as when they apply ideas to real-world issues.
  • Whether a person accepts the data as proof depends on their presumptions or views regarding how observations relate to a theory.
  • A creative hypothesis is developed by a scientist and may be refuted by testing it against evidence or established truths.
  • Evidence can refute a hypothesis by demonstrating facts that are at odds with it. In contrast, the presence of evidence does not preclude the possibility of future, undiscovered evidence supporting the idea.

Therefore, it is the power of material evidence that wins, not the authority of experts that

proves an answer in Science.

what is a photoelectric?explain the terms ground state and excited state with the help of labelled diagram
brilliants [131]

Answer: Photoelectric is characterized by or involving the emission of electrons from a surface by the action of light.

Photoelectric effect is the emission of electrons when a radiation of frequency higher than the threshold frequency falls on the surface of an element. The substance which undergoes photoelectric effect is called as photoelectric.

Ground state is the state representing the lowest energy  state.

Excited state is the state which represents a high energy state.

An electron in ground state absorbs energy to move to the excited state.

PLZ HELP, GIVING BRAINLIEST!!
Veseljchak [2.6K]

Answer:

2.29 moles of Cr₂O₃ are produced

Explanation:

This is the reaction:

4 Cr + 3O₂ → 2Cr₂O₃

Ratio for this equation is 4:2, so 4 moles of chromium can produce the half of moles of chromium(III) oxide

4.58 mol of Cr may produce (4.58  .2)/4 = 2.29 moles of Cr₂O₃

If you are pushing a shopping cart and you start pushing harder , what happens?
olya-2409 [2.1K]
The kinetic energy of the shopping cart increases. This speeds up the energy rate of friction between the wheel and the floor giving off more kinetic energy so the speed rate can increase (depending on how much your pushing it) Hope this helps :)
