Answer:
chlorine
Explanation:
Because in periodic table across the period from left to right, ionization energy increases due to increase in the nuclear charge as more and more electrons are added to the same shell.
Camouflage, mimicry, and animals' body parts and coverings are physical adaptations. The way in which an animal behaves is an adaptation, too—a behavioral adaptation . Behaviors that animals are born knowing how to do are instincts . A lion preying upon a zebra and a bird building a nest are examples of instincts.
A chemical formula of a molecule is an expression which states the number and type of atoms<span> present in a </span>molecule of a substance. While the structural formula, is a formula of <span>a chemical compound that is a graphic representation of the molecular </span>structure<span>, showing how the atoms are arranged.</span>
Consider the following homogenous reaction:
aA + bB ⇔ cC + dD
The equilibrium constant is written as:
Kc = ([C]^c * [D]^d) / ([A]^a * [B]^b)
Therefore the equilibrium constant is the ratio of the concentration of the products to concentration of the reactants at equilibrium.
For a heterogenous reaction, the species that are not in the same physical state as the rest of the chemical species are omitted from the expression. Considering the previous reaction, if reactant A was solid and the remaining were gaseous, the expression will be:
Kc = ([C]^c * [D]^d) / [B]^b
This is an incomplete question, here is a complete question.
What are the concentrations of hydrogen ion and hydroxide ion in household ammonia, an aqueous solution of NH₃ that has a pH of 11.00?
Answer : The concentrations of hydrogen ion and hydroxide ion in household ammonia is, and
Explanation :
As we know that the aqueous solution of ammonia is ammonium hydroxide that is,
The equilibrium reaction will be:
Given:
pH = 11.00
First we have to calculate the hydrogen ion concentration.
pH : It is defined as the negative logarithm of hydrogen ion concentration.
Now we have to calculate the pOH.
Now we have to calculate the hydroxide ion concentration.
Therefore, the concentrations of hydrogen ion and hydroxide ion in household ammonia is, and
