What does lower case k stand for?

1 answer:

4 0

Just for more clarification, lowercase k is the rate constant. Uppercase K is the equilibrium constant. You can actually use k to find K (equilibrium constant). K=k/k' This means that the equilibrium constant is the rate constant of the forward reaction divided by the rate constant of the reverse reaction

A gas occupies 1200 litres at 2 atm pressure. To what pressure must it be compressed to occupy 60 litres at the same temperature

MArishka [77]

P2 = 40 atm

Explanation:

Given:

P1 = 2 atm

V1 = 1200 L

V2 = 60 L

P2 = ?

Using Boyle's law and solving for P2,

P1V1 = P2V2

P2 = (V1/V2)P1

= (1200 L/60 L)(2 atm)

= 40 atm

Revise and repeat: Is more water always better? Create your own experiments to find the ideal amount of water for each kind of p

sergij07 [2.7K]

More water is not always better. For example; cacti only need water about every two weeks, the same with succulent plants. Not every plant needs to be watered every day, or the plant may be overwatered and die.

Determine the number of bonding electrons and the number of nonbonding electrons in the structure of xef2.

lys-0071 [83]

Answer: There are 4 bonding electrons and 18 non-bonding electrons.

Explanation: To determine the number of bonding and non-bonding electrons, we will use lewis dot structure for the molecule $XeF_2$

Lewis dot structure is the structure in which the valence electrons around an atom is shown in a molecule. It also tells us about the number of bonds present between the two neighboring atoms.

Valence electrons of Fluorine = 7

Valence electrons of Xenon = 8

In $XeF_2$

Total number of valence electrons = [(1 × 8) + (2 × 7)] = 22 electrons

From, the structure attached below, the number of bonds present = 2. Hence, the bonding electrons will be = 4 electrons
