Ar stands for the element argon
Answer is: A) The shape.
Name of this organic chemical compound is cyclohexane.
Cyclohexane is cycloalkane (the monocyclic saturated hydrocarbons).
Cyclohexane has single covalent bond and carbons have sp3 hybridization as other alkanes (for example propane).
Propane is alkane, organic compound. Carbons in propane have sp3 hybridization (carbon’s 2s and three 2p orbitals combine into four identical sp3 orbitals). Orbitals in sp3 hybridization have a tetrahedral arrangement and form single (sigma) bonds.
Experiment because she is actually taking the samples and testing them.
The answer is: Dividing the number of molecules in the sample by Avogadro's number.
The Avogadro’s number is the number of atoms in 12 grams of the isotope carbon-12 (¹²C).
Na is Avogadro number or Avogadro constant (the number of particles, in this example carbon, that are contained in the amount of substance given by one mole).
The Avogadro number has value 6.022·10²³ 1/mol in the International System of Units; Na = 6.022·10²³ 1/mol.
For example:
N(Ba) = 2.62·10²³; number of atoms of barium.
n(Ba) = N(Ba) ÷ Na.
n(Ba) = 1.3·10²⁴ ÷ 6.022·10²³ 1/mol.
n(Ba) = 2.158 mol; amount of substance of barium.
Answer:
As the average kinetic energy increases, the particles move faster and collide more frequently per unit time and possess greater energy when they collide. Both of these factors increase the reaction rate. Hence the reaction rate of virtually all reactions increases with increasing temperature
HOPE THIS HELPED!!!!!!!!!!!!!! XDDDDD
