You need to specify the experiment to get an answer. However, most experiments require qualitative data (descriptive, non-numerical data) and quantitative data (measured, numerical data).
<u>Answer</u>:
The phenomenon of marble cancer is due to ACID RAIN.
<u>Explanation</u>:
The marble corrosion is a process by which the marbles or limestone used in construction of monuments and buildings is corroded away by the acid rain. The sulphur-dioxide and nitrogen oxides present in the atmosphere undergoes certain chemical reaction causing this acid rain. These chemical in the acid rain converts the calcium present in the limestone or marble into salt.
Also, this marble cancer leads to change the appearance and color. Sometime due to over corrosion the monuments or building causes them disintegrate .Tajmahal is one of the monument affected by marble cancer. the white color of tai mahal is slowly turning into yellow due to this marble cancer.
150÷3=50
350÷4=87.5
(50+87.5)÷2
137.5÷2
=68.75
Answer:
mass of CO₂ = 5.402 g
Explanation:
At STP, 1 mole of any gas takes up 22.4L of volume
Thus, 1 mole = 22.4 L
1 L = 1 mole ÷ 22.4
Therefore, 2.75 L = 2.75 mole ÷ 22.4 = 0.123 moles
Molecular weight of CO₂ = 44 g/mole
mass of CO₂ = molecular weight * number of moles = 44 g/mole * 0.123 moles
mass of CO₂ = 5.402 g
