Answer: 1.06 kg
Explanation:
Density is defined as the mass contained per unit volume.
Given :
Density of mercury = 
volume of cylinder = volume of mercury = 
where r = radius of cylinder = 
h= height = 25.0 cm
Putting in the values we get:
volume of mercury =
(1kg=1000g)
Thus mass of mercury required to fill a hollow cylinder having an inner diameter of 2.00 cm to a height of 25.0 cm is 1.06 kg.
Answer:
The answer to your question is 1.40 moles of N₂O
Explanation:
Balanced equation
NH₄NO₃ ⇒ N₂O + 2 H₂O
2 -------- N ---------- 2
4 ------- H ---------- 4
3 ------- O ---------- 3
Process
1.- From the balanced equation, we know that 1 mol of NH₄NO₃ produces 1 mol of N₂O so, we use proportions to find the number of moles produced when 1.40 moles of NH₄NO₃ react.
1 mol of NH₄NO₃ ------------- 1 mol of N₂O
1.40 moles -------------- x
x = (1.40 x 1) / 1
x = 1.40 moles of N₂O are produced
Answer: oxygen, hydrogen, sodium, chlorine, lead, iron. Examples of compounds include water ( or hydrogen oxide ) H2O; and Sodium Chloride, NaCl.
