Answer:
3.44 liters
Explanation:
before we start we must convert the celcius to kelvin by adding 273
Next we must Know we are using charles law and the eqation is V1/T1= V2/T2 we must convert it to V1 T1 / T2
so its must equal 7.80 times 698 divided by 308 wich gives you 3.44 liters
I think it takes about 278g but I'm not 100% sure
Answer:
It's the third option
Explanation:
Because the particles of the solid are very closed together and packed they can barely move, causing the item to have a fixed shape and volume.
Answer:
64 g/mol
Explanation:
In one molecule of FeSO4, we notice that we have 4 atoms
Hence, we can say that the molar mass of Oxygen in 1 unit/molecule of FeSO4 is 4 times the molar mass of Oxygen
Molar mass of Oxygen atom (O) = 16 g / mol
Molar mass of Oxygen in FeSO4 = 16 * 4 g / mol
Molar mass of Oxygen in FeSO4 = 64 g / mol
Answer:
Explanation:
The first one is CrO. The Chromium has the same charge as the oxygen so mol numbers are dropped.
The Second one is CrO2 The two oxygens have a charge of 2(-2) = -4. To balance this, the Chromium must have a charge of +4 Cr(Iv)O2
The third one is can be set up like this
Cr + 3(-2) = 0
Cr - 6 = 0
Cr = 6
Therefore the formula is Cr(vi)O3
The last one is a bit tricky. Follow this carefully. There are 2 Crs and 3Os.
The formula looks like this
2Cr + 3(-2) = 0
2Cr - 6 = 0
2Cr = 6
Cr = 3
The formula is Cr(iii)2 O3
