Answer:
The identity does not matter because the variables of Boyle's law do not identify the gas.
Explanation:
The ideal gas law confirms that 22.4 L equals 1 mol.
Answer: See explanation
Explanation:
Based on the information given in the question, the ranking from the first step to the last step goes as follows:
1. Dissolution of salt into cations and anions
2. Hydration of anions
3. Hydration of cations
4. Dissolved cations and anions begin to deposit as a solid salt.
5. Rate of dissolution is equal to the rate of recrystallization.
The question is missing the choices and these are CHCl3, CF4, CS2 or Br2.A polar molecule is one in which the atoms are organized such that one end of the molecule has a positive charge and the conflicting end has the opposite or negative charge. So in the given choices above, the most polar one CHCl3 this actually the only polar one in the choices. The explanation behind this is it has the same shape as CCl4 molecule, but one of the Chlorine atoms has been substituted by a Hydrogen atom. We know that Hydrogen has a weaker electronegativity in contrast to Chlorine, so electron density along the h-c bond is dragged away from the Hydrogen and in the direction of the ccl3 fragment, resulting in a polar molecule.
We can calculate the new volume of the gas using the Combined Gas Law:
(P1 x V1) / T1 = (P2 x V2) / T2
The initial volume, pressure, and temperature were 280 mL, 1.3 atm, and 291.15 K (changing the temperature into Kelvin is necessary), and the final volume, pressure, and temperature is V2, 3.0 atm, and 308.15 K. Plugging these values in and solving, we find that:
(P1 x V1) / T1 = (P2 x V2) / T2
(1.3 atm x 280 mL) / 291.15 K = (3.0 atm x V2) / 308.15 K
V2 = 128.42 mL
This makes sense considering the conditions, a small increase in temperature would make the gas expand but a significant increase in the pressure would cause the volume to decrease.
Hope this helps!
The chemical reaction of SiCl2→ Si +Cl2 is
A decomposition reaction
<u><em>Explanation</em></u>
- <u>A decomposition reaction</u> is type of chemical reaction which involve breaking down a compound into smaller compounds or individual elements.
- <em>SiCl2→ Si +Cl2 is a decomposition reaction because SICl2 is broken down into Si and Cl2</em>
- Decomposition reaction often involve input of energy in form of heat to break down compounds
