Gallium trichloride is the name of GaCI3.
Explanation:
The compound having chemical formula GaCl3 is Gallium trichloride.
The rules for naming a compound according to IUPAC is:
The net charge should always be zero in ionic compounds the prefixes are used as mono, di, tri and so on.
Metal name should come first.
Non-metal name proceed it
The anion ends with suffix 'ide'
Ga³+ + Cl- ⇔ GaCl3
In this gallium Ga is metal and Cl is non-metal with prefix 3.
In solid state the Gallium trichloride exists as a dimer which has formula as
Ga2Cl6.
It has the property of being soluble in all the solvents including alkanes.
Answer:
3. 2.00 L of air at 100°C has twice the pressure of the same 2.00 L of air at 50°C
Explanation:
1) doubling the pressure of a gas doubles its volume
This is incorrect because by increasing the pressure volume is going to be decreased.
2) 2.00 L of air at 227°C has twice the pressure of the same 2.00 L of air at 23°C
This is also incorrect because 2 L air at 227 °C will have the pressure more than twice time as compared to the 2L air at 23°C.
3. 2.00 L of air at 100°C has twice the pressure of the same 2.00 L of air at 50°C
This is correct;
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
thus, by increasing the temperature pressure is also goes to increase in the same ratio.
4. halving the pressure of a gas halves its volume
This is incorrect because halving the pressure of gas increasing its volume.
Answer:
Fossils & common ancestors
Explanation: Fossils provide evidence that evolution has taken place by fossil records. Fossil records provide evidence species have changed over time. Hope this helped! :)
Answer:
Density can be calculated by dividing an object's mass by its volume. Since different materials have different densities, measuring an object's density can help determine which materials are in it. Finding the density of a metal sample can help to determine its purity.
