Answer:
1.2 x 10>24 (2.0)(6.022 x 10>23)
Explanation:
How many formula units are in 2.0 moles of Fe(NO3)2?
Answer:
The temperature at 581.2 mL volume was 242.8 K.
Explanation:
Using Charle's law
Given ,
V₁ = 581.2 mL
V₂ = 830.5 mL
T₁ = ?
T₂ = 347 K
Using above equation as:
<u>The temperature at 581.2 mL volume was 242.8 K.</u>
If one were to match the ratio of atoms of the elements found in this molecular formula of artificial sweetener it would be :
Carbon - 7 atoms
Hydrogen - 5 atoms
Nitrogen - 1 atom
Oxygen - 3 atoms.
Answer:
Explanation:
- 1 mole of any substance contains Avogadro number of particles i.e, 6.022 × 10^23 particles.
- number of of particles in n moles of a substance = n*Avogadro number
- number of moles of Ne in 2.0 g of Ne= 2/20=0.1
[number of moles=given weight/ gram molecular weight]
- so, number of particles in 2.0 g of Ne = number of particles in 0.1 moles of Ne= 0.1(6.022 × 10^23)
=
Answer:
The movement of heat by convection in the asthenosphere causes the rock of the mantle to slowly move in huge streams. ... As the rock of the asthenosphere moves in different directions, it carries parts of the lithosphere along with it. The lithospheric rock can't stretch, so it breaks into pieces--forming the plates.
