B. Aluminum, Al3+, aluminum ion is correct
Chloride would be negative, Iron has Fe for the symbol, potassium is K....
D = m / V
d = 1300 g / 743 cm³
d = 1.749 g/cm³
One way that I would really describe these kind of mirrors would be like first, these kind of mirrors are for sure <span>virtual, upright, smaller. And this would be only due mainly because this the kind of mirror this would be. So based from my information. So based from your options, the answer would most likely be one of the options that would practically fit this. This would be known to be "</span><span> upright and smaller than object".</span>
The correct answer would be option 1. The mole ratio of butane to carbon dioxide is 1:4. Looking at the balanced chemical reaction, we see that we need 2 moles of butane to produce 8 moles of carbon dioxide. So, it is 2:8. Simplifying this by dividing both to 2, we have 1:4.
6.270/56.11 = 0.1117447870 /0.1117.. ≈ 1
19.67/44.01 = 0.446943876 /0.1117.. ≈ 4
8.055/18 = 0.4475 /0.1117.. ≈ 41 mole of compound forms 4 moles of both CO2 and H2O, so the empirical formula will be C4H8
As this gives molar mass of 56.11, this is also the molecular formula
This could be cyclobutane, or butene
