A glasier can cause an eroision miles away from eachother
Answer:
1. Find the molar mass of NO2 (46.01)
2. Find the number of moles in 25 g of NO2 (by dividing 25 by the molar mass) 25/46.01 = .54
3. For every 3 moles of NO2 there are 2 moles of HNO3. multiply the number of moles of NO2 by 2/3
.54 x 2/3 = .36
4. Finally, multiply this number by the molar mass of HNO3 (63.018)
.36 x 63.018 = 22.68 g HNO3
Explanation:
Answer:
sugars such as dextrose and sucrose increase the surface tension of water. The effect was interpreted as a depletion of the solute molecules from the water-air interface.
Answer:
Mass of arsenic chloride produced is 0.363 g
Explanation:
Given data:
Mass of arsenic chloride produced = ?
Mass of arsenic react = 0.150 g
Mass of chlorine = excess
Solution:
Chemical equation:
2As + 3Cl₂ → 2AsCl₃
First of all we will calculate the number of moles of arsenic.
Number of moles = mass/ molar mass
Number of moles = 0.150 g/ 75 g/mol
Number of moles = 0.002 mol
Now we will compare the moles of arsenic with arsenic chloride.
As : AsCl₃
2 : 2
0.002 : 0.002
Mass of arsenic chloride produced:
Mass = number of moles × molar mass
Mass = 0.002 × 181.28 g/mol
Mass = 0.363 g
