I would say that the answer has to be C
Since there is no change in mols on both sides of the equation the mass is constant
<span>The fog in the mirror is the condensation of water vapor as it touches a colder surface. When you are running cold water you just cool down everything around it. Now the vapor coming from the hot shower will mostly condense right there and will not reach the mirror.</span>
Answer is: in steel, the solvent is iron and the solute is the carbon.
Solution is homogeneous mixture composed of two or more substances.
In the solution, the solute molecules interact with solvent molecules.
Solvent (usually a liquid, but can also be a solid or a gas) is a substance that dissolves a solute. Iron is solvent because there is more iron than carbon and they are both solid state.
Solvent is always the same state of matter as the solution.
In ideal solution the forces of attraction between the solute-solute and the solvent-solvent and solute-solvent molecules are the same.
Answer : The orbitals that are used to form each indicated bond in citric acid is given below as per the attachment.
Answer 1) σ Bond a: C
O
.
Explanation : The sigma bonds in the 'a' position involves carbon atom which undergoes
hybridisation and has
orbitals of carbon and as well as oxygen atoms involved in the bonding.
Answer 2) π Bond a: C has π orbitals and O also has π orbitals.
Explanation : The pi-bond at the 'a'position has carbon and oxygen atoms which undergoes pi-bond formation. And has pi orbitals of oxygen and carbon involved in the bonding process.
Answer 3) Bond b: O
H has only S orbital involved in bonding.
Explanation : The bonding at 'b' position involves oxygen and hydrogen atoms in it. It has
hybridized orbitals and S orbital of hydrogen involved in the bonding.
Answer 4) Bond c: C
O
Explanation : The bonding involved at 'c' position has carbon and oxygen atoms involved in it. Both the atoms involves the orbitals of
hybridized bonds.
Answer 5) Bond d: C
C 
Explanation : The bonding involved at the position of 'd' involves two carbon atoms. Therefore, they undergo
hybridization. The orbitals involved in this hybridization are also
.
Answer 6) Bond e: C1 containing O
C2 
Explanation : The bonding at the 'e' position involves two carbon atoms on is containing oxygen with double bonds and the C2 carbon atom. The carbon containing oxygen has
hybridized orbitals involved in the bonding; whereas C2 carbon ha
orbitals.
The question is missing the graphics required to answer which I have attached as an image.
There are four different representations of the orientation of water molecules around chloride anion. Let's first analyze the water molecule.
We have H-O-H as the structure of water. The oxygen atom is more electronegative than the hydrogen atoms, which results in a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom.
The chloride anion is a negative charge. Therefore, the water molecules should orient themselves with the hydrogen atoms facing the chlorine atom as the partial positive charge on the hydrogen atoms will be attracted to the negative charge of the chlorine atom.
The correct representation is shown in graph 3 which shows all hydrogen atoms facing the chlorine anion.
