The absolute temperature of a gas increased four times while maintaining a constant volume. What happens to the pressure of the

gas?

andre [41]2 years ago

Following the ideal gas law PV = nRT, and changing it in terms of pressure we get P = nRT/V. When the absolute temperature of a gas is increased four times while maintaining constant volume, the pressure of the gas also increases four times. The pressure increases because temperature is directly proportional with pressure.

The image shows sedimentary rock layers with index
vichka [17]

Layer 2 and layer 9 are the same relative age.

Explanation:

The statement that best describes the rock layers is that Layer 2 and layer 9 are the same relative age..

The relative age is used in placing sedimentary rocks in order of their occurrence.

To do this, we apply the sedimentary laws.

The ones applicable here are:

  • Principle of superposition states that in an undisturbed sequence, the oldest layer is at the base and youngest on top.
  • Principle of cross cutting states that a fault and intrusion are younger than the rocks they cut through.
  • Principle of fossil and fauna succession states that fossils and fauna succeed on another in a determinable form.

We see that layers 2 and 9 have the same fossil and are the same lithological units.

An atom or ion has 41 neutrons, 36 protons, and 36 electrons. Identify the clement symbol, and determine the mass
Paul [167]

The atom is krypton and its symbol is Kr.

the mass number is 41 + 36 = 77

its charge is 0 as it is a noble gas.

Which of the following elements has the strongest ionization energy: Mg or Cl? Define ionization
Mila [183]

Answer:

Cl

Explanation:

The element Cl will have the strongest ionization energy from the given choices. Most non-metals have higher ionization energy compared to metals.

Ionization energy is the energy required to remove the most loosely held electron from the gaseous phase of an atom.

  • As you go from left to right on the periodic table, it increases progressive
  • From top to bottom, the ionization energy reduces significantly.
  • The attractive force between the protons in the nucleus and the electrons plays a very important role.
  • In metals, they have very large atomic radius, the attractive force on the outer electrons is very weak.
  • This is not the case in non-metals

Calculate the oxidation numbers of the elements in this equation<br> 2 Al2O3 → 4 Al + 3 O2
riadik2000 [5.3K]

Explanation:

Answer

Open in answr app

The rule used here is that the algebraic sum of the oxidation numbers of all the atoms a molecule is zero.

Al2O32× ( oxidation number of Al)+3× ( Oxidation number of O )  = 0

2× ( Oxidation number of Al) +3(−2)=0

2× ( oxidation number of Al) +6

∴ Oxidation number of Al =+3
