I definitely think he mostly observed that it was clear in color.
Explanation:
Answer: An alloy is made up of two kinds of metals. This alloy is uniform in appearance. This material would be classified as a homogeneous mixture
Answer:
Diphosphorus pentoxide
Carbon dichloride
BCl3
N2H4
Explanation:
These are all covalent compounds. To name covalent compounds, you add prefixes to the beginning of their names depending on what the subscript is of each element. The prefixes are:
1: Mono
2: Di
3: Tri
4: Tetra
5: Penta
6: Hexa
7: Hepta
8: Octa
9: Nona
10: Deca
For example, since the first one is Phopsphorus with a 2 next to it, you add the prefix Di to it.
If the first element in the compound only has one, meaning no number next to it, you do not say mono. This is why we just say "Carbon" for the second one instead of "Monocarbon."
Finally, you always have to end the second element in the compound with "ide." So, "chlorine" becomes "chloride," "oxygen" becomes "oxide," and so on.
We can approach this problem using the ideal gas law which is as follows:
PV = nRT
P = pressure
V = volume
n = number of moles
R = gas constant, 0.08206 Latm/Kmol
T = temperature
We are asked to solve for temperature and can rearrange the equation to solve for T:
PV = nRT
T = PV/nR
Now we simply plug in the data to solve for T:
T = (4.50 atm)(10.0 L)/(3.00 mol)(0.08206 Latm/Kmol)
T = 183 K
The temperature of the gas is 183 K.
