Condensation. It is caused by a change in pressure and occurs when warm air rises, cools, and collides with an object
I.e. a stove pot
Answer:
0.1046M NaOH solution
Explanation:
a. KHP is a salt used as primary standard because allows direct standarization of bases solutions. The reaction of KHP with NaOH is:
KHP + NaOH → H₂O + KP⁻ + Na⁺
<em>As you can see, KHP has 1 acid proton that reacts with NaOH.</em>
<em />
Molar mass of KHP is 204.22g/mol; 0.5527g of KHP contains:
0.5527g KHP × (1mol / 204.22g) = 2.706x10⁻³moles of KHP. As 1 mole of KHP reacts per mole of NaOH, at equivalence point you must add <em>2.706x10⁻³moles of NaOH</em>
<em />
As you spent 25.87mL of the solution, molarity of the solution is:
2.706x10⁻³moles of NaOH / 0.02587L = <em>0.1046M NaOH solution</em>
Pyrogallol is the product of heating gallic acid, known as trihydroxybenzene with the chemical formula of C6H6O3 or C6H3(OH)3.
At STP, the volume of Cl2 is 22.4 L/mol.
11.5 L Cl2 * (1 mol Cl2/ 22.4 L Cl2)= 115/224 mol Cl2.
115/224 mol Cl2* (70.90 g Cl2/ 1 mol Cl2)= 36.4 g Cl2.
The final answer is 36.4 g Cl2.

The answer would be
C) Both may occur when plates slide past each other.
Hope this helps! ;)
