What can acid rain do to buildings and statues

Corrosion and dissolution

Explanation:

Acid rain typically can corrode metallic parts of buildings thereby weakening them. Acids can generally affect most compounds in which metals are no exceptions. We find corrugated roofing sheets becoming weaker and less durable as the rain persists. This is due to the acidity of the rain in such an environment.

Acids reacts vigorously with limestone. Limestone can be used in construction works and it is one of the key component of cements. In contact with acid rain, cemented plasters on buildings can be dissolved and rendered weak.

Marble is a metamorphic limestone. It is rich in calcium carbonate. Due to its beautiful nature, it is used in building statues and for a host of stone works. Acid rain can dissolve statues and also make them weak. This reaction defaces them.

i believe the answer is three water molecules

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
