Answer:
The mass of 1.26 mole of water, H₂O, is 22.68 grams
Explanation:
Molar mass is the amount of mass that a substance contains in one mole. In other words, the molar mass of an atom or a molecule is the mass of one mole of that particle and its unit is g/mole.
In this case, being:
the molar mass of water H₂O is:
H₂O= 2*1 g/mole + 16 g/mole= 18 g/mole
Then you can apply the following rule of three: if 18 grams are present in 1 mole of H2O, how much mass is present in 1.26 moles of water?

mass= 22.68 grams
<u><em>The mass of 1.26 mole of water, H₂O, is 22.68 grams</em></u>
Answer:
in the attached image is the reaction mechanism.
Explanation:
The first reaction (reaction 1) shown in the attached image is the Wolff-Kishner reduction, which is characterized when the carbonyl is reduced to an alkane in the presence of a hydrazine and a base. In reaction 1, the aldehyde reacts with hydrazine to produce oxime. This mechanism begins with the attack of the amine on the carbonyl group. Proton exchange happens and the water leaves the molecule.
In reaction 2, the KOH is deprotoned in nitrogen and organized to form the bond between the nitrogen molecule. this deprotonation releases the nitrogen gas
<h2>Acetic Acid</h2>
Explanation:
- Initial alcohol that is formed from methane is methanol that can be converted to acetic acid.
- Methanol in presence of
and hydrogen gas gets oxidized to acetic acid with the release of water.
Hence, compound A will be Acetic acid.
→ 
- The acetic acid formed can be transformed into -
→ 
The product formed is methane and carbon monoxide.
2.
→ 
The product formed is formaldehyde and water.
3.
→ 
The product formed is sodium acetate, carbon dioxide, and water.
Answer:Today they will practice measuring different liquids. They will use a container called a graduated cylinder to measure liquids. Graduated cylinders have numbers on the side that help you determine the volume. Volume is measured in units called liters or fractions of liters called milliliters (ml).
Explanation:
is the type of orbital hybridization of a central atom that has one lone pair and bonds to four other atoms.
<h3>What is
orbital hybridization?</h3>
In the context of valence bond theory, orbital hybridization (or hybridisation) refers to the idea of combining atomic orbitals to create new hybrid orbitals (with energies, forms, etc., distinct from the component atomic orbitals) suited for the pairing of electrons to form chemical bonds.
For instance, the valence-shell s orbital joins with three valence-shell p orbitals to generate four equivalent sp3 mixes that are arranged in a tetrahedral configuration around the carbon atom to connect to four distinct atoms.
Hybrid orbitals are symmetrically arranged in space and are helpful in the explanation of molecular geometry and atomic bonding characteristics. Usually, atomic orbitals with similar energies are combined to form hybrid orbitals.
