Answer:
cup c will dissolve the fastest
Explanation:
Because the particle size is smaller, the water can dissolve them quicker as the smaller the particle, the more surface are for the water to dissolve.
for the sn1 reaction, draw the major organic product, identify the nucleophile, substrate, and leaving group, and determine the rate limiting step.
C4H9OH is the substrate, Br- is the nucleophile and H2O is the leaving group.
In an SN1 reaction, the rate limiting step is the formation of the carbocation. The carbocation is formed as water which is the leaving group departs. After the leaving group departs, the nucleophile (Br-) attacks to yield the major organic product. The protonation of the -OH group is the first step in the reaction.
It then follows that, C4H9OH is the substrate, Br- is the nucleophile and H2O is the leaving group.

why does the total volume of water and alcohol decrease when the liquids were mixed together?
Answer: I think the alcohol molecules slip between the water molecules and take up that space, so you have less that you started with.

Cuci
copper(1) chloride
O
copper chloride
copper(ll) chloride
DONE
The correct name of the compound CuCl is copper I chloride.
An ionic compound is formed two atoms when one loose electrons and the other atoms gains those electrons. Ionic bonds are actually an ion pair, a pair of oppositely charged ions held together by electrostatic interaction. Transition metals are elements with incompletely filled d orbitals. Copper is a transition element.
The compound CuCl is named copper I chloride. We can see that the copper is in the +1 oxidation state in this compound hence the name.

in an oxidation-reduction reaction, how is the reducing agent changed?
Explanation: The additional terminology comes from the definition that, within redox processes, a reductant transfers electrons to an oxidant; hence, the reductant (reducing agent) loses electrons, so is oxidized, while the oxidant (oxidizing agent) gains electrons, so is reduced.
In an oxidation-reduction reaction, the reducing agent loses electrons and loses potential energy, Therefore, option (C) is correct.
What is a reducing agent?A substance that loses its electrons in a redox reaction to other substances and gets oxidized is called a reducing agent. A reducing agent is one of the reactants which reduces the other reactant by donating the electrons to the reactant of an oxidation-reduction reaction.
If the reducing agent can't pass electrons to another reactant in a reaction, then the reduction process does not occur and the reaction cannot proceed.
In redox reactions, when an electron loses potential energy as a result of the transfer and energy is released. Electrons with more potential energy are associated with less electronegative atoms and less potential energy is associated with a more electronegative atom (such as O).
Therefore, the reducing agent loses electrons and loses potential energy in a redox reaction.

How many significant digits are found?
Answer:
4
Explanation:
There are 4 significant figures because when there is not a decimal, then only numerical values over 0 are counted. So the numbers counted in sig figs are 2049, and none of the other 0s.
So if it was 204,900,000,000.0, then it would have 12 significant figures.

Explain why graphite conducts electricity.
Answer in terms of the structure and bonding in graphite.
Answer:
Diamond has a giant molecular structure. Each carbon atom is covalently bonded to four other carbon atoms. A lot of energy is needed to separate the atoms in diamond. This is because covalent bonds are strong, and diamond contains very many covalent bonds.
Graphite on the other hand has flat layers of carbon atoms held by weak van der Waal's forces which makes Graphite a weak object and easily breakable.
As graphite contains layers of carbon atoms. The layers slide over each other easily because there are only weak forces between them, making graphite slippery. These electrons can move through the graphite, carrying charge from place to place and allowing graphite to conduct electricity.One valence electron of each carbon atom remains free, Thus making graphite a good conductor of electricity. Whereas in diamond, they have no free mobile electron. Hence there won't be flow of electrons That is the reason behind diamond are bad conductor electricity.These electrons are free to move between the layers in graphite, so graphite can conduct electricity.The forces between the layers in graphite are weak. This means that the layers can slide over each other.

An atom of radium (Ra) forms a monatomic ion.
Which ion does it most likely form?
a- Ra2-
b- Ra-
c- Ra2+
d- Ra+
Answer:
The atomic number of the element Radium (Ra) is 88. It is an alkaline earth metal. Electronic configuration of Radium (Ra) will be [Rn]7s^{2}[Rn]7s
2
It belongs to the group IIA of the periodic table. Alkaline earth metals that belong to the group IIA of the periodic table lose the valence electrons to form a +2 ion.
Therefore, Radium with an electronic configuration of [Rn]7s^{2}[Rn]7s
2
will lose the two 7s electrons to form the cation with +2 charge.

Water, made of 1 oxygen atom bonded with 2 hydrogen atoms, is what
Answer:
It is a water molecule.
Explanation:
A water molecule consists of two atoms of hydrogen linked by covalent bonds to the same atom of oxygen. Atoms of oxygen are electronegative and attract the shared electrons in their covalent bonds.
Answer:
A water molecule is an example of a molecule created through covalent bonding. Water is made up of one oxygen atom and 2 hydrogen atoms, hence the chemical symbol H2O. A hydrogen atom is made up of 1 proton at its core and 1 electron that revolves around the core in a three-dimensional orbit.

why it is necessary to draw a Lewis diagram before predicting the shape of a molecule
To determine the shapes of molecules, we must become acquainted with the Lewis electron dot structure. Although the Lewis theory does not determine the shapes of molecules, it is the first step in predicting shapes of molecules. The Lewis structure helps us identify the bond pairs and the lone pairs.
