Weathering is the physical or chemical process where rocks are
broken down to form sediments.
• Physical weathering does not change the rock’s composition.
• Chemical weathering does change the rock’s composition
• Erosion is the process where forces such as water, wind, ice, or gravity
transport sediments to some remote location

Cadium
Down a period, atomic radii decrease from left to right due to the increase in the number of protons and electrons across a period.
Answer:
Heated water is more dense than melted snow because water as liquid is denser than ice. Ice floats on water, which means that it has less density than water. Heated water is warmer and more dense than melted ice.
Explanation:
Answer:
<em>The solution with the lowest pH is 0.1 M HCl.</em>
Explanation:
Since the three solutions have the same concentration (0,1M) it is only necessary to look at the pKa of each solution.
Also, knowing that a higher pKa means a lower Ka, because pKa = -Log (Ka). Thus, a lower Ka means a lower concentration of protons with a higher pH ( pH = -Log [H+].
The HCl doesn't have a pKa because is a strong acid that dissociates completely. Therefore, this solution produces a lower pH. Looking at the pKa of acetic acid and formic acid solutions, the second with the lowest pH is the formic acid solutions and the higher pH is for the acetic acid solution.
