Answer:
C.
The pan will be the same temperature as the stove.
Explanation:
Explanation:
Formula to calculate specific rotation is as follows.
Specific rotation (
) = 
where,
= observed rotation
c = concentration in g/ml
l = path length in dm
It is given that,
c =
= 0.02 g/ml
l = 20 cm = 2 dm (as 1 dm = 10 cm)
Therefore, calculate the specific rotation as follows.
Specific rotation (
) = 
= 
=
Thus, we can conclude that the specific rotation of this compound is
.
Answer: a.KOH
Potassium hydroxide is an ionic compound where the K+ is the cation and OH−is the anion. At the same time, the compound also contains a covalent bond since the anion, OH−is formed from electron sharing between the O and H atoms.

Explanation:
The number of molecules of isopently acetate is 4.63 x 10¹⁵ molecules
<u><em>calculation</em></u>
Step 1: find the moles of isopently acetate( C₇H₁₄O₂)
moles = mass÷ molar mass
From periodic table the molar mass of C₇H₁₄O₂
= (12 x7 ) + (1 x14) +(16 x2) =130 g/mol
moles = 1 x10⁻⁶ g÷ 130 g/mol = 7 x 10⁻⁹ moles
step 2 ; use the Avogadro's law constant to calculate the number of molecules
That is according to Avogadro's law 1 mole = 6.02 x 10²³ molecules
7 x 10⁻⁹ moles = ? molecules
<em>by cross multiplication</em>
= { (7 x 10⁻⁹ moles x 6.02 x10²³ molecules) / 1 mole} = 4.63 x 10¹⁵ molecules
