Answer:
5.8 x 6.022x10^23 =3.49276x10^24
or
5.8 x 6.02x10^23 =3.4916x10^24
One mole of lithium (Li) is equal to 6.022 x 10^23 atoms of lithium.
Avogadro's constant
Voltaic cells are used as a source of electrical power. By their nature, they produce direct current<span>.
</span>A voltaic cell, or galvanic cell<span> is an </span>electrochemical cell that uses a chemical reaction to produce electrical energy. The cell consists of two metals: one called anode where oxidation (loss of electrons) occurs and the other cathode where reduction (gain of electrons) occurs.The salt bridge connect the anode with the cathode. It is the <span>chamber of electrolytes necessary to complete the circuit in a voltaic cell.
</span><span>The external circuit is used to conduct the flow of electrons between the electrodes of the voltaic cell and includes a load.</span>
<span>The key to gathering the electron flow is to separate the oxidation and reduction half-reactions, connecting them by a wire, so that the electrons must flow through that wire.</span>
Answer:
i also had this question.
Explanation:
Answer:
The C-O stretch of phenol
Explanation:
Electron delocalization causes the of the phenol to have partial double bond character, whereas the  of the cyclohexanol is a pure single bond. Again, we know as the bond order or bond strength increases the absorption occurs at larger wave number. So, the  stretch of the phenol occurs at larger wave number.
<h3>
Answer:</h3>
482.596 grams
<h3>
Explanation:</h3>
The relationship between moles, molar mass and mass of a compound is given by;
In this case;
The compound in question is P₂O₅
Molar mass of P₂O₅ = 141.94 g/mol
Rearranging the formula;
Mass = Moles × molar mass
Therefore;
Mass of P₂O₅ = 3.4 mol × 141.94 g/mol
= 482.596 grams
Therefore, mass of P₂O₅ is 482.596 grams
