The formula for chromium (III) phosphate is CrPO4. This compound exists as a green crystal and as a hydrated form violet crystal having the formula of CrPO4•4H2O. The formula for cobalt(II) phosphate octahydrate is Co3(PO4)2•8H2O. It exists as an hydrated form.
Lead oxide. Pb is lead, coming from german word for lead Blei.
When combined with oxygen, oxygen would be the more electronegative element, making it at the end.
Ionic bonds are stronger because it involves complete transfer of electrons between the atoms which means that their intermolecular force of attraction is stronger than covalent bonding.
Hope this helps!
Answer:
A wave is like water rippling in a pond.
Explanation:
Water tanks are used to examine water waves and their properties. Two types of waves, circular and linear, can be produced in water. The crests of the waves behave like convergence on the target and it is observed in the lower part of the tank as a clear zone. On the other hand, the depressions darken in the lower part of the water tank.
Answer:
619.2 K
Explanation:
We can solve this problem by using Charle's Law, which states that:
"For a fixed mass of an ideal gas kept at constant pressure, the volume of the gas is directly proportional to its absolute temperature"
Mathematically:
where
V is the volume of the gas
T is the absolute temperature
The equation can be rewritten as follows for a gas that undergoes a transformation at constant pressure:
where in this problem:
is the initial volume of the gas
is the initial temperature
is the final volume of the gas
Solving for T2, we find the final temperature:
Converting into Celsius degrees,
