Answer:
Density, solubility, melting point, boiling point, polarity, etc.
Density - Mass divided by volume = density (scale and beaker can be used)
Boiling point- Can be determined by the capillary method (where an inverted capillary is put in the liquid you’re finding out for and the liquid is heated)
The first one im pretty sure
333,000 Joules is the amount of energy (heat) in joules required to raise the temperature of 5 kg of iron from 50°C to 200°C.
Explanation:
Data given:
mass of iron 5 Kg or 5000
initial temperature = 50 degree centigrade
final temperature = 200 degrees centigrade
change in temperature (Δ T= 200 -50 degrees centigrade)
= 150 °C
cp (specific heat capacity of iron) = 0.444j/gram C
q (heat supplied) = ?
applying the formula,
q=mcΔT
putting the values in the equation:
q = 5000 X 0.444 X150
q = 333,000 Joules of energy.
The heat required 333,000 Joules of energy is required.
Answer:
acid rain falls in areas that have air pollution
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
