The first statement is true. To remember this, ionic compounds are a mix of the two different types of elements (metal/nonmetal). Electrons are transferred from one atom to the other.
Answer:
The structures are shown below.
Explanation:
The conjugate base of an acid is the base that is formed when the acid lost a proton (H⁺) in a solution. For a generic acid, HA, the conjugate base is A⁻.
The pyrrole is a base that has a ring with 4 carbons and 1 nitrogen and double bonds between carbons 1 and 2 and between carbons 3 and 4. The nitrogen is between carbons 1 and 4 and has a bond with a hydrogen. When it dissociates, it can lose the hydrogen, and form the conjugate base, which is shown in the picture below. Nitrogen has 5 valence electrons, and in the conjugate base it will do 2 bonds, so it will have 2 lone pairs and 1 free electron.
The cyclopentadiene is formed by a ring of 5 carbons and has double bonds between carbons 1 and 2, and between carbons 3 and 4. When in solution, one of the hydrogens attached in carbons with double bonds will be lost (because it's the more acidic hydrogen, and the structure will be more stable because of the double bond!), so the conjugate base structure is shown below.
1. <span>A material that is malleable and conducts electricity is most likely a metal. The correct option among all the options that are given in the question is option "C".
2. "Malleable" is the </span>physical property that makes wax good for making sculpture molds. <span>The correct option among all the options that are given in the question is option "B".
3. </span>Filtration can be used to separate mixtures based on the size of their particles. <span>The correct option among all the options that are given in the question is option "D".</span>
K, ca, sc is the right answer. Take a look at table S of your chemistry reference table.
According to the eqn, 3 ea of one will produce 3 ea of the other.
so if 8 moles are produced, 8 moles of reactants are required.
