Answer-Figure P38.63a
is a three-dimensional sketch of a birefringent crystal. The dotted lines illustrate how a thin, parallefaced slab of material could be cut from the larger specimen with the crystal’s optic axis parallel to the faces of the plate.”
Sorry if it’s it correct
M has lost an electron.
It's oxidation.
Answer: increase pressure and decrease temperature.
Explanation:
Increasing pressure uses force to make the gas molecules come closer together. (Decreasing pressure allows the molecules to spread out) Decreasing temperature will also cause the molecules of gas to come together closer. (Heat excites molecules causing them to spread out and therefore expand)
A.) covalent
c.) covalent
b.) ionic
d.) covalent
Answer:
atoms Ti = 2.193 E23 atoms
Explanation:
- 1 mol ≡ 6.022 E23 atoms
- mm Ti = 47.867 g/mol
⇒ atoms Ti = (20.9 g Ti)×(mol/47.867 g)×(6.022 E23 atoms/mol)
⇒ atoms Ti = 2.193 E23 atoms
