Marble statues and buildings weather more quickly today than when first constructed. explain how the ph of water plays a role in this process. answer it in at least a few you!

Rain is more acidic than it used to be, that is why the marble statues and buildings weather quicker than before. The pH of rainwater furthered away from its normal pH value. According to www3.epa.gov, it states, “Normal, clean rain has a pH value of 5.0 and 5.5, which is slightly acidic.” Over the years, the rain became more acidic due to the constant recycling of water. The website also states that automobiles produce sulfur dioxide making the rain more acidic. Therefore, the reason why the marble statues and buildings are eroding quicker is because of the acidic rain

For cyclohexane compounds drawn in a chair conformation:   -axial bonds are vertical  -equatorial bonds are parallel to two bonds within the ring.  thus, as i assume the chair conformation is drawn:   -the x group is in an axial position, as are the five other vertical bonds.  -three axial bonds are on the top face of the ring  -the other three axial bonds are on the bottom face  the position of the second substituent on each ring carbon is equatorial.  gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other.  drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1.  click this link and watch some academic videos that may you more understand the topic
