Answer:
53 meters = 53000 millimeters
Explanation:
In this question we have to convert meters into millimeters .
By metric conversion,
Since, 1 meter = 1000 mm
Therefore, 53 meters = 53 × 1000
= 53000 millimeters
53 meters = 53000 millimeters is the answer.
When the reaction equation is:
CaSO3(s) → CaO(s) + SO2(g)
we can see that the molar ratio between CaSO3 & SO2 is 1:1 so, we need to find first the moles SO2.
to get the moles of SO2 we are going to use the ideal gas equation:
PV = nRT
when P is the pressure = 1.1 atm
and V is the volume = 14.5 L
n is the moles' number (which we need to calculate)
R ideal gas constant = 0.0821
and T is the temperature in Kelvin = 12.5 + 273 = 285.5 K
so, by substitution:
1.1 * 14.5 L = n * 0.0821 * 285.5
∴ n = 1.1 * 14.5 / (0.0821*285.5)
= 0.68 moles SO2
∴ moles CaSO3 = 0.68 moles
so we can easily get the mass of CaSO3:
when mass = moles * molar mass
and we know that the molar mass of CaSO3= 40 + 32 + 16 * 3 = 120 g/mol
∴ mass = 0.68 moles* 120 g/mol = 81.6 g

<h2>Answer and Explanation </h2>
The body of water means the occurrence of water on earth’s surface. Examples are oceans, lakes, seas, ponds, and pools. The major bodies of water are:
- Pacific ocean is the biggest and deepest of Earth's oceanic divisions. It stretches from the Arctic Ocean in the direction to the Southern Ocean.
- Atlantic ocean is another giant of the world's oceans. It includes nearly 20 percent of the Earth's exterior and nearly 29 percent of its water covering space.
- The Indian Ocean is the third largest Ocean in the world. It is surrounded by Asia, Africa, and Australia.
- Arctic ocean is the smallest and shallowest of the world's five main oceans.
- Mediterranean sea is a sea is attached to the Atlantic Ocean.
