The size of the rocks
Explanation:
One key factor in the rate of chemical weathering is the size of the rocks. The rate of chemical weathering like other chemical reaction depends on the size of the rocks.
- Chemical weathering is the decomposition and decay of rocks.
- In chemical weathering, a rock unit undergoes a chemical change.
- For an effective chemical weathering of a rock, physical disintegration of a rock piece must have occurred first.
- The surface area exposed proportionally affects the rate of chemical weathering.
- Smaller chunks of rocks have a large surface area and they are weathered faster.

are easily broken
Explanation:
The double covalent bond within unsaturated hydrocarbons are easily broken.
Answer:
At end point there will a transition from pink to colorless.
Explanation:
As the student put the vinegar in the titrator and NaOH in the beaker, it means that he has poured phenolphthalein in the NaOH solution.
The pH range of phenolphthalein is 8.3-10 (approx), it means it will show pink color in basic medium.
So on addition of phenolphthalein in NaOH the solution will become pink in color.
When we start pouring vinegar from titrator neutralization of NaOH will begin.
On complete neutralization , on addition of single drop of vinegar the solution will become acidic and there will be complete disappearance of pink color solution in the beaker.
1.05moles
Explanation:
Given parameters:
Number of molecules of C₂H₆ = 6.29 x 10²³molecules
Unknown:
Number of moles = ?
Solution:
The mole is the amount of substances that contains Avogadro's number of particles i.e 6.02 x 10²³
To find the number of moles:
number of moles = 
number of moles = 
number of moles = 1.05moles
