Solute - substance that dissolves.
alcohol - solute
water - solvent
Answer:
0.3M
Explanation:
Step 1:
Data obtained from the question. This include the followingb:
Volume of acid (Va) = 90mL
Concentration of acid (Ca) = 0.2M
Volume of base (Vb) = 60mL
Concentration of base (Cb) =....?
Step 2:
The balanced equation for the reaction. This is given below:
HBr + NaOH —> NaBr + H2O
From the balanced equation above,
The mole ratio of the acid (nA) = 1
The mole ratio of the base (nB) = 1
Step 3:
Determination of the concentration of the base, NaOH.
The concentration of the base can be obtained as follow:
CaVa /CbVb = nA/nB
0.2 x 90 / Cb x 60 = 1
Cross multiply
Cb x 60 = 0.2 x 90
Divide both side by 60
Cb = 0.2 x 90 /60
Cb = 0.3M
Therefore, the concentration of the base, NaOH is 0.3M
Between equatorial positions, the F-P-F angle is 120°, and between axial and equatorial positions, it is 90°.
<h3>What in chemical bonding is equatorial position?</h3>
Equatorial Organic Chemistry Illustrated Glossary. Equatorial: In cyclohexane, a bond that runs parallel to the ring's axis (i.e., it follows the chair's equator), or a group joined by such a bond. Positions A are axial, and positions E are equatorial.
<h3>Why do equatorial positions have greater stability?</h3>
As was said in the preceding section, the equilibrium favors the more stable conformer because the chair conformation, in which the methyl group is equatorial, lowers steric repulsion. All monosubstituted cyclohexanes share this property.

Answer:
<em>The parent isotope in the given elements is Radium 226.
</em>
Explanation:
The two elements given in the question are radioactive elements radon and Helium which are formed after an Alpha decay happens in the radium 226 to form Radon 222.
Radon has many isotopes out of which here radon 222 is formed which is a noble gas that is odourless colourless but Radioactive. Again in this reaction helium is formed which is again a noble gas and very light in weight.
Answer:
True
