The surface area is greater with the crushed solid so more of the material is exposed to the gas allowing more reactions
Answer : Neutrons.
Explanation : Usually in nuclear fission reactions the atoms with a heavy nucleus is bombarded with neutrons. Which breaks the parent atom into many smaller atoms resulting in fission products.
Answer:
780 moles e⁻
Explanation:
N⁺⁵ in NO₃⁻ requires 2(5e⁻) => 1/2 mole N₂(g)
That is, NO₃⁻ + 2(5e⁻/mole N₂ formed) => 1/2N₂
NO₃⁻ + 10e⁻/mole N₂ formed => 1/2N₂
∴ 78 mole NO₃⁻ requires 780 moles e⁻ => 1/2(78) moles N₂ = 39 moles N₂
1) Dawn dish soap has a density of 1.06 g/mL. If the mass of a sample of the liquid is 1.00 g what is the volume?
Answer:
v = 0.94 mL
Explanation:
Density:
Density is equal to the mass of substance divided by its volume.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Given data:
Density of soap = 1.06 g/mL.
Mass = 1 g
Volume = ?
Solution:
d = m/v
v = m/d
v = 1 g/1.06 g/mL
v = 0.94 mL
2) Maple syrup has a density of 1.37 g.mL. What is the mass of 1.0 L of the maple syrup?
Answer:
m = 1370 g
Given data:
Density of soap = 1.37 g/mL.
Mass = ?
Volume = 1.0 L ( 1000 mL)
Formula:
D=m/v
D= density
m=mass
V=volume
Solution:
d = m/v
m = d × v
m = 1.37 g/mL × 1000 mL
m = 1370 g
3) The density of gasoline is 0.754 g/mL. A drop of gasoline has a mass of 22 g what is the volume?
Answer:
v = 29.2 mL
Given data:
Density of soap = 0.754 g/mL.
Mass = 22 g
Volume = ?
Formula:
D=m/v
D= density
m=mass
V=volume
Solution:
d = m/v
v = m/d
v = 22 g/0.754 g/mL
v = 29.2 mL
There are 6 hydrogen atoms in every molecule of ethanol
